RV Dump Stations In Comstock, Texas

29.6840° N, 101.1730° W

Quick Overview

Comstock is a tiny community deep in west Texas, sitting on US-90 in the Chihuahuan Desert near the Pecos River. This is genuinely remote country, with long stretches of highway that have no services, so RVers who come here need to arrive self-sufficient. There is several dump station counted for the Comstock area, and a portion of the local options are paid, with none free. In a place this isolated, that is exactly what you would expect, and the one facility that matters is the state park just up the road.

Seminole Canyon State Park, nine miles west of Comstock on US-90, is your anchor for dumping and fresh water. It spreads across 2,172 acres with water and electric campsites plus primitive sites, and it offers dump facilities for campers. The park is also the reason most RVers detour here at all: guided tours reach some of the oldest rock art in North America, 4,000 to more than 10,000 years old, and over 10 miles of trails run to the canyon rims and the Rio Grande. If you need to dump but are not camping, take care of it in Del Rio, about 30 miles east, where full services exist.

Getting here is simple but demands planning. US-90 is the main east-west route, with no interstate nearby and I-10 about 60 miles north. Fill both fuel and fresh water in Del Rio before you head west, because Comstock's fuel is very limited and groceries are extremely sparse. Carry extra drinking water, especially in summer when highs approach 98 degrees. Beyond the rock art, the Pecos River Bridge is the tallest in Texas at 270 feet, and Judge Roy Bean's historic Langtry sits 20 miles west. For camping, tours, and fees, check the official Texas Parks and Wildlife Seminole Canyon page before you arrive.

Traveling to Comstock by RV

Comstock sits on US-90, the main east-west highway through remote west Texas. There is no interstate nearby, with I-10 about 60 miles north, so nearly everyone arrives on US-90 from Del Rio, roughly 30 miles east, or from Langtry to the west. The highway is open, scenic, and very empty, with long gaps between services, so it demands a full tank and fresh water before you set out. Seminole Canyon State Park is nine miles west of Comstock right off US-90, and the Pecos River Bridge with its rest area is adjacent.

Del Rio is your resupply hub for fuel, fresh water, and groceries, since Comstock has very limited fuel and extremely sparse shopping. Top off everything before you drive west, because the next reliable fill is back behind you. Carry extra drinking water in summer, watch for flash flooding in the canyons after rain, and keep an RV GPS running. For campsite reservations, tour times, and current fees at the state park, use the official Texas Parks and Wildlife site.

Before You Go: RV Trip Essentials

Dump stations are only one piece of the trip puzzle. Before you set out for your trip to Comstock, Texas, 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 Comstock

Comstock is cheap to visit in the sense that there is little to spend money on, but the dump situation is still paid. The several counted dump station in the area charges a fee, and a portion of local options are paid with none free, which is normal for such an isolated spot where Seminole Canyon State Park is the only developed facility for miles.

The most efficient approach is to bundle tank service, fresh water, and a night into a Seminole Canyon State Park stay, which keeps your per-chore cost low and often qualifies for the Texas State Parks Pass if you are touring several parks. Fuel is where the real budgeting happens: buy it in Del Rio where prices and availability are better, since Comstock fuel is very limited and you do not want to pay a premium or run dry on US-90. Stock groceries in Del Rio too, carry extra water to avoid emergency stops, and you can enjoy this remote desert country for very little beyond the state park fees.

Best Time to Visit Comstock by RV

❄️

Winter

Nov - Feb

38F - 62F

Crowds: Medium

Mild days and cold nights make winter a comfortable time to camp in the Chihuahuan Desert. This is prime season for Seminole Canyon, so reserve state park sites ahead for holiday weekends.

🌸

Spring

Mar - May

56F - 84F

Crowds: Medium

Warm and windy. Good hiking weather before the summer heat, but watch for flash flooding in the canyons after rain and secure loose gear against the wind.

☀️

Summer

Jun - Aug

72F - 98F

Crowds: Low

Extremely hot desert conditions. Camping is thin and demanding, so carry extra water, run early-morning outings only, and never rely on finding fuel or supplies out here.

🍂

Fall

Sep - Oct

56F - 82F

Crowds: Medium

Pleasant and one of the best windows. Cooler air returns, the rock-art tours are comfortable, and the empty US-90 drive is at its best under fall skies.

Explore the Comstock Area

A few hard-won tips for the Comstock stretch. First, fill both fuel tanks and your fresh water in Del Rio, 30 miles east, before you head out. Comstock has almost no services, and US-90 runs long and empty, so self-sufficiency is not optional out here. Second, make Seminole Canyon State Park your base for dumping, water, and hookups, and reserve a site in the cooler months when the park is busiest.

Third, the rock-art tour is the whole point, so plan your stay around the guided-tour schedule and go in the morning before the desert heat peaks. Fourth, respect flash-flood risk in the canyons and never camp in a wash when rain threatens. Finally, do not rush past the roadside history: the Pecos River Bridge is the tallest in Texas at 270 feet, and the Judge Roy Bean Visitor Center in Langtry, 20 miles west, is a genuinely fun Wild West stop on one of the most scenic empty highways in the state.

Frequently Asked Questions About Dump Stations in Comstock

Are there free RV dump stations in Comstock, TX?

No. The dump option in the Comstock area is paid, and the count is thin because this is extremely remote west Texas. Comstock is a tiny community on US-90 with almost no services, so there is no municipal RV dump. Your realistic choice is Seminole Canyon State Park, nine miles west, which has water and electric campsites and dump facilities tied to a stay. If you need a free dump, you will not find one out here, so plan tank service around the state park or handle it in Del Rio, about 30 miles east, before you head into the desert.

Where can I dump tanks near Comstock?

Seminole Canyon State Park, nine miles west of Comstock on US-90, is the practical dump location in this area. It is a 2,172-acre park with water and electric campsites, primitive and full-facility camping, and dump facilities for campers. Because Comstock itself has essentially no RV services, the state park is your anchor for tanks and fresh water. Alternatively, take care of dumping in Del Rio about 30 miles east, where full services exist, before you commit to the remote stretch of US-90. Out here, planning ahead beats hoping to find a facility on the fly.

Can I camp at Seminole Canyon State Park in an RV?

Yes. Seminole Canyon State Park offers water and electric campsites along with primitive sites across its 2,172 acres, nine miles west of Comstock on US-90. It is the main reason RVers come to this corner of Texas, thanks to guided tours of some of the oldest rock art in North America and more than 10 miles of trails running to the canyon rims and the Rio Grande. Reserve ahead for the cooler months, which are peak season, and check the official Texas Parks and Wildlife page for current site availability, tour times, and fees before you arrive.

Is the Comstock area dump station free or paid?

It is paid. There is several dump station counted for the Comstock area, and a portion of the local options charge a fee, with none free. That is expected in a place this isolated, where Seminole Canyon State Park is effectively the only developed facility. Because the count is so thin and the desert is unforgiving, do not treat dumping as a casual errand out here. Plan it around your state park stay or handle it in Del Rio before you drive the empty stretch of US-90. Confirm the park's dump hours and camping fees ahead so you are not caught short.

How remote is Comstock, and what should I bring?

Very remote. Comstock is deep in west Texas on US-90, with long stretches of highway that have no services, so you need to arrive self-sufficient. Fill both fuel and fresh water in Del Rio, about 30 miles east, before you head out, because Comstock's fuel is very limited and groceries are extremely sparse. Carry extra drinking water, especially in summer when highs hit the upper 90s in the Chihuahuan Desert. There is no interstate nearby; I-10 is about 60 miles north and US-90 is the main east-west route. Treat this as a plan-ahead desert trip, not a spontaneous one.

Where do I get fuel and water near Comstock?

Del Rio, roughly 30 miles east on US-90, is your resupply hub for fuel, fresh water, and groceries. Comstock has very limited fuel and extremely limited shopping, so do not rely on it. Langtry, to the west, is another small stop but is not a full-service town either. The rule out here is simple: top off everything in Del Rio before you drive west, because the gaps between services on US-90 are long and unforgiving. Fill your fresh tank and both fuel tanks, stock food, and confirm your dump plan at Seminole Canyon State Park before you leave the last real town behind.

What is there to see around Comstock for RVers?

The star is Seminole Canyon State Park, nine miles west, home to ancient rock art dating 4,000 to more than 10,000 years, with guided tours required to see the pictographs and over 10 miles of trails to the canyon rims and the Rio Grande. Right nearby, the Pecos River Bridge is the tallest in Texas at 270 feet, spanning 1,300 feet across the Pecos canyon, with a rest area for views. Twenty miles west in Langtry, the Judge Roy Bean Visitor Center tells the Wild West story of the Law West of the Pecos. This empty, scenic stretch of US-90 is a destination in itself.

Are the Seminole Canyon rock art tours worth it?

Absolutely. Seminole Canyon protects some of the oldest rock art in North America, and the pictographs can only be seen on a guided tour, which is exactly what makes the visit special. Rangers walk you down into the canyon and explain the 4,000 to 10,000-plus-year-old paintings in context, something you cannot get on your own. Plan your stay around the tour schedule, since times are limited and the desert heat pushes outings to mornings. Check the official Texas Parks and Wildlife page for current tour times and fees, reserve ahead in the busy cooler months, and wear real shoes and sun protection for the canyon walk.

When is the best time to RV near Comstock?

Fall through spring, roughly October to April, is the season here. Winter brings mild days and cold nights that are very comfortable for desert camping, and fall and spring offer pleasant hiking weather, though spring gets windy. Summer is the one to avoid if you can, with extreme Chihuahuan Desert heat pushing highs near 98 degrees, thin camping, and real demands on your water supply. Whatever the season, watch for flash flooding in the canyons after rain and never head out low on fuel or water. The cooler months also make the rock-art tours and the empty US-90 drive far more enjoyable.

Is there flash flood risk near Comstock?

Yes. The canyons around Comstock and Seminole Canyon State Park are prone to flash flooding after rain, even when the storm is miles away upstream. Never camp in or hike through a dry wash when rain is in the forecast, and heed any ranger or highway warnings. The desert can go from bone dry to a dangerous torrent quickly, so treat low-lying canyon areas with respect. Combine that with the extreme summer heat and the remoteness, and the message is the same: plan carefully, carry extra water, watch the weather, and do not push into the backcountry without checking conditions at the state park first.

Can I overnight my RV at a rest area near Comstock?

Texas generally allows overnight parking at highway rest areas, so a rest stop along US-90 can work for a night in a pinch, including the Pecos River Bridge rest area with its canyon views. That said, your better bet in this area is Seminole Canyon State Park nine miles west, where you get a real campsite, water and electric hookups, and a dump facility. Rest-area overnighting out here means no services and full self-sufficiency, so make sure you have water, fuel, and a plan. For any multi-night stay, the state park is safer, more comfortable, and lets you actually see the canyon.

What highway is Comstock on and how do I get there?

Comstock sits on US-90, the main east-west highway through this remote part of west Texas.
