RV Dump Stations In Campbellsport, Wisconsin

43.5978° N, 88.2790° W

Quick Overview

Campbellsport is a small village in Fond du Lac County set right in the rolling hills of the Northern Kettle Moraine, and for RVers it is really the front door to the Kettle Moraine State Forest Northern Unit. That matters when you need to dump, because the dump stations around here live inside the state forest rather than at a downtown gas station.

The one to know is the sanitary dump station at the Mauthe Lake Recreation Area, just south of the village at N1490 County Road GGG. The forest provides a dump station plus recycling and garbage for registered campers there, alongside 135 campsites, 51 of them with electric, and a shower building. Mauthe Lake is open for camping year-round, though the water and the dump station itself are seasonal and shut down once hard freezes arrive, so plan to dump spring through fall. Of the roughly several options our directory tracks near Campbellsport, Mauthe Lake is the most reliable one tied to a real campground.

To use it you need a Wisconsin State Park vehicle admission sticker just to enter the forest, sold daily or annually through the DNR, with federal passes honored for the vehicle fee but not camping. The other Northern Unit campgrounds fill out your options: New Prospect Horseriders Campground has 22 sites with 20, 30, and 50-amp electric, and Long Lake near Dundee is tent and basic camping with drinking water and swimming beaches but no hookups. None of them offer in-site sewer, so the Mauthe Lake dump station is where everyone empties tanks on the way out. Around the camping you get the Henry S. Reuss Ice Age Visitor Center, the Ice Age National Scenic Trail, Dundee Mountain, and lake swimming, which makes Campbellsport an easy two or three-day base. Roll in on WI-67 through downtown, buy your sticker, top off propane and water in the village, and settle into the kettles.

Traveling to Campbellsport by RV

Campbellsport sits on WI-67, which runs straight through downtown as Main Street and was recently rebuilt, so the pavement is smooth. WI-28 feeds in from the east, US-45 runs a few miles east of the village, and US-41 lies to the west; Interstate 41 is roughly 12 to 15 miles west near Fond du Lac. Most RVers arrive on WI-67 off US-45 from the south or on WI-28 from the east. The through-highways carry no notable low bridges or weight limits and handle a big rig fine.

The catch is the last few miles. County roads into the Kettle Moraine, like County GGG to Mauthe Lake and County G to the forest headquarters, are narrow, hilly, and winding, so take them slow. Buy your Wisconsin State Park vehicle admission sticker before or on entry, since you need it to reach the campgrounds and the dump station. Reserve sites through the Wisconsin DNR ahead of summer weekends, and fill fresh water and propane in the village first.

Before You Go: RV Trip Essentials

Dump stations are only one piece of the trip puzzle. Before you set out for your trip to Campbellsport, Wisconsin, it's worth taking thirty minutes to check that the basics are in place — the four areas below are where unprepared RVers most often get stung.

Check your RV insurance coverage

A standard auto policy rarely covers a Class A, Class C, or travel trailer the way a dedicated RV insurance policy does. If you're financing a motorhome, lenders typically require comprehensive and collision; full-timers should additionally price in vacation liability and personal belongings coverage. Rates vary widely by state and travel pattern — compare quotes from multiple RV-focused carriers before each season.

Know your roadside assistance options

RV-specific roadside plans tow motorhomes and trailers that regular AAA coverage won't touch — flat beds, mobile mechanics, tire service for duallies, and even emergency lockouts at remote campgrounds. Good plans cover your spouse and trailer even if you're driving a separate vehicle, and some include trip interruption reimbursement if a breakdown costs you a reservation.

Decide about an extended warranty early

Original manufacturer warranties on new RVs typically run 12–24 months — shorter than most buyers realize. An extended service contract (essentially a mechanical breakdown policy) covers the appliances, slides, levelling systems, and drivetrain components that can run $3,000–$10,000 to replace. The time to price one is before the factory coverage expires, not after something breaks.

Set up a travel rewards card for fuel and fees

A no-annual-fee travel or gas rewards card pays for itself on a single month of RV travel. Expect to spend $400–$800 per week combined on fuel, campgrounds, and propane — 3–5% cash back on gas alone covers the next oil change. For bigger trips, a sign-up bonus can offset campground fees for the whole season.

Dump Station Costs in Campbellsport

Camping around Campbellsport is state-forest priced, which keeps it reasonable. Your two costs are the Wisconsin State Park vehicle admission sticker to enter the forest and the nightly camping fee, both set by the Wisconsin DNR. The sticker comes as a daily pass or an annual, and if you plan to visit other Wisconsin state parks and forests on the same trip, the annual quickly beats paying daily each time. Federal passes like America the Beautiful waive the vehicle fee but not the camping fee.

The dump station at Mauthe Lake is provided for registered campers, so for most visitors it is effectively bundled into the camping fee rather than a separate charge. Electric sites cost a little more than basic sites, and there are no sewer hookups to pay for since everyone shares the central dump station. Add affordable propane refills through AmeriGas and village fuel, and a couple of nights in the Kettle Moraine runs well under what a private resort park would charge for the same stay.

Best Time to Visit Campbellsport by RV

❄️

Winter

Nov - Feb

13F - 30F

Crowds: Low

Freezing, snowy, and windy. Mauthe Lake stays open for camping year-round, but the water system and sanitary dump station are shut down for the season, so arrive with empty holding tanks and a cold-weather setup.

🌸

Spring

Mar - May

35F - 55F

Crowds: Low

Cool and muddy through April, then the hardwoods green up fast by May. Trails are quiet and sites are wide open, though early-season blackflies and changeable weather come with the territory.

☀️

Summer

Jun - Aug

58F - 81F

Crowds: High

Peak season across the Kettle Moraine. Warm humid days, swimming beaches open, and weekends at Mauthe Lake fill early, so reserve electric sites well ahead through the Wisconsin DNR.

🍂

Fall

Sep - Oct

38F - 58F

Crowds: Medium

The best time to come. Crisp air, glowing kettle-and-kame color through September and October, and thinning crowds. The dump station and water usually run until the season closes with the first hard freezes.

Explore the Campbellsport Area

A few things we would pass along to a friend heading here. First, if you need a dump station and electric, book Mauthe Lake specifically; it is the closest campground to the village, open year-round, and the one with the sanitary dump station. New Prospect has the higher-amp electric if you are running a hungry rig, and Long Lake is the pretty tent-and-basic option with no hookups.

Second, buy your Wisconsin State Park vehicle admission sticker up front, because you cannot even drive in to reach the dump station without it. Third, respect the seasonal shutoff: Mauthe Lake stays open for winter camping, but the water and dump station close with the first hard freezes, so arrive with empty tanks if you come off-season. Fourth, take County GGG and County G slowly with a big coach, they are narrow and hilly. Finally, fill propane with AmeriGas and top off groceries and water in the village or in Fond du Lac before you head into the forest, where services are limited to the campgrounds.

Frequently Asked Questions About Dump Stations in Campbellsport

Where is the nearest RV dump station to Campbellsport, WI?

The closest dump station is at the Mauthe Lake Recreation Area inside the Kettle Moraine State Forest Northern Unit, just south of the village at N1490 County Road GGG. The forest provides a sanitary dump station plus recycling and garbage stations there for registered campers. Because it sits in a state forest, you need a Wisconsin State Park vehicle admission sticker to enter, and the dump station is meant for people camped in the forest rather than drive-up public use. Of the roughly several dump options our directory tracks near Campbellsport, Mauthe Lake is the most reliable one attached to a real campground.

Can I use the Mauthe Lake dump station without camping there?

The sanitary dump station at Mauthe Lake is provided for registered campers, so the intended use is for people staying in the Kettle Moraine State Forest Northern Unit. If you are booked at Mauthe Lake, Long Lake, or New Prospect, you can dump on your way out. If you are not camping in the forest, do not assume drive-up access; call the forest headquarters in Campbellsport first to confirm current policy and any fee. You still need a Wisconsin State Park vehicle admission sticker just to drive into the recreation area where the dump station sits.

Do I need a permit or sticker to reach the dump station near Campbellsport?

Yes. The dump station is inside the Kettle Moraine State Forest Northern Unit, and every vehicle entering the forest needs a Wisconsin State Park vehicle admission sticker, sold as an annual or a daily pass through the Wisconsin DNR. Federal passes such as the America the Beautiful pass and National Parks passports are honored to waive the vehicle admission fee, but they do not cover camping fees. If you plan to hit other Wisconsin state parks and forests on the same trip, the annual sticker pays for itself quickly compared with buying a daily pass each time.

Is the Campbellsport dump station open year-round?

Mauthe Lake campground itself is open for camping year-round, which is unusual for Wisconsin, but the water system and the sanitary dump station are seasonal. Once the camping season winds down and hard freezes set in, the water is shut off to prevent frozen pipes, and the dump station closes with it. In practice that means the dump station is reliable from roughly spring through fall and unavailable in deep winter. If you are winter camping at Mauthe Lake, arrive with empty holding tanks and plan to dump elsewhere on your way out of the area.

What campgrounds near Campbellsport take RVs?

The Kettle Moraine State Forest Northern Unit is the main RV base around Campbellsport. Mauthe Lake has 135 sites including 51 with electric, plus showers and the area dump station, and it is open year-round. New Prospect Horseriders Campground offers 22 family sites wired for 20, 30, and 50-amp electric, the highest amperage in the Northern Unit, and it welcomes RVers even though it leans equestrian. Long Lake near Dundee is tent and basic camping with no in-site hookups but has drinking water, sanitary facilities, and swimming beaches. Reserve any of them through the Wisconsin DNR reservation system.

Are there full hookups with sewer at the Kettle Moraine campgrounds?

No. The Northern Unit campgrounds offer electric at Mauthe Lake and New Prospect, but individual sites do not have sewer or water hookups. You get power at the electric sites, drinking water at spigots around the loops, and a central sanitary dump station at Mauthe Lake to empty your tanks before you leave. If you need true full hookups with sewer at the pad, you will want a private RV park toward Fond du Lac or West Bend. For most RVers, an electric site at Mauthe Lake plus the dump station on the way out covers the trip fine.

What highways lead into Campbellsport for an RV?

Campbellsport sits on WI-67, which runs right through downtown as Main Street and was recently reconstructed, so the pavement is smooth. WI-28 comes in from the east, US-45 runs a few miles east of the village, and US-41 lies to the west. Most RVers arrive on WI-67 off US-45 from the south or on WI-28 from the east. Interstate 41 is roughly 12 to 15 miles west near Fond du Lac. The through-highways have no notable low bridges or weight limits, but the county roads into the forest are narrow and hilly, so slow down on those.

Is there overnight RV parking in the village of Campbellsport?

Not really. Campbellsport is a small village with a compact downtown grid, and there is no formal RV overnight parking or a big retail lot set up for it the way you find in larger towns. The intended overnight stop for RVers is inside the Kettle Moraine State Forest Northern Unit at a designated campground like Mauthe Lake. If you just need to rest, plan your day so you roll into a reserved forest site rather than trying to find a spot in the village. It keeps you legal and puts you next to the dump station and the trails.

Where can I get propane and fuel near Campbellsport?

AmeriGas serves the Campbellsport area for RV propane bottle refills and tank exchange, so you can top off before a trip into the forest. For fuel, there are gas and diesel stations along WI-67 through the village and on US-45 a few miles east, including a Mobil on Highway 45. For anything more specialized or a wider selection of stores, Fond du Lac is about 20 minutes west with full-size fuel stops and supermarkets. We would fill propane and fresh water before heading into the Kettle Moraine, since services inside the forest itself are limited to the campgrounds.

What is there to do around Campbellsport while camping?

Plenty of glacial scenery. The Henry S. Reuss Ice Age Visitor Center just north of town has exhibits on the Kettle Moraine landforms, a short film, and a back deck looking out toward Dundee Mountain. The Ice Age National Scenic Trail runs through the Northern Unit, with the moderate Parnell Segment and Parnell Tower giving big views over the forest. Dundee Mountain is a glacial kame with a short loop trail, and Mauthe and Long Lakes have three swimming beaches plus fishing and boating. It is an easy two or three-day stay built around hiking and the water.

When is the best time to RV around Campbellsport?

Late spring through fall is the window. Summer is peak season with warm humid days, open swimming beaches, and the busiest weekends, so reserve electric sites at Mauthe Lake early. September and October are our favorite, when the kettle-and-kame hardwoods turn color, the air goes crisp, and the crowds thin out while the dump station and water usually still run. Spring is quiet but muddy and buggy early on. Winter camping is possible since Mauthe Lake stays open, but the water and dump station shut down, so it is really a cold-weather, empty-tanks proposition.

How do I reserve a campsite in the Kettle Moraine Northern Unit?

Reservations for Mauthe Lake, Long Lake, and New Prospect run through the Wisconsin DNR reservation system, and you can book several months ahead. Summer weekends and the electric sites at Mauthe Lake go fastest, so lock those in early if you want power. You still need a Wisconsin State Park vehicle admission sticker on top of the camping fee to enter the forest. First-time visitors should note that the forest headquarters is in Campbellsport at N1765 County Road G, and staff there can answer questions about site sizes, the dump station schedule, and which loops fit a bigger rig.

Can a big rig get into the Kettle Moraine campgrounds near Campbellsport?

Larger RVs can camp here, but pick your site and route carefully. Mauthe Lake and New Prospect have sites that handle sizable rigs, though the older forest loops were not laid out for 40-foot coaches, so check site length when you reserve and ask the Campbellsport forest headquarters which loops are roomiest. The bigger challenge is the approach: county roads like County GGG and County G into the kettles are narrow, hilly, and winding. Take them slow, watch overhanging trees on the tighter loops, and you will be fine. When in doubt, the New Prospect electric sites tend to be more open.

Where is the nearest RV dump station to Campbellsport, WI?

The closest dump station is at the Mauthe Lake Recreation Area inside the Kettle Moraine State Forest Northern Unit, just south of the village at N1490 County Road GGG.
