Every RV trip ends the same way: tanks full, looking for a dump station. Around Willis, TX the search is easier than in most of rural Texas because the Lake Conroe camping corridor keeps options close, but costs, hours, and access rules differ enough that knowing them ahead saves a detour with full tanks. Travelers passing through on I-45 and campers wrapping up a lake weekend want the same 3 things: a station that is open, a fee that is fair, and a freshwater fill nearby.
Lake Conroe RV Campground by RJourney covers the practical end of this. The park has a dump station that handles departures for $15 and a freshwater fill station for top-offs, and because every site has full sewer hookups, guests staying at the park rarely need either until the day they leave. This guide lists the dump station details near Willis, what they cost, and the etiquette that keeps the line moving.
The Dump Station at Lake Conroe RV Campground
The park’s dump station sits at 12351 FM 830 Rd in Willis, west of I-45 on the north shore of Lake Conroe, and costs $15 per use. A freshwater fill station handles potable top-offs, and the on-site store carries RV supplies if a hose or fitting gives out mid-trip. Check in at the office, which runs Monday to Friday 9 AM to 5 PM and Saturday 10 AM to 4 PM, or call (936) 256-3268 to confirm access before routing over with full tanks; a call center covers daily 7 AM to 9 PM CT. Worth knowing if you are choosing where to camp rather than just where to dump: every site at the park is full hookup with water, sewer, and 30 or 50-amp electric, so staying here mostly removes the dump station from your trip math. Guests typically use it once, on the way out.
Dump Station Etiquette and Cost Basics
The routine is the same at every station, and doing it in order keeps the line moving. Glove up, connect the sewer hose to the station inlet before opening anything, then dump the black tank first and the gray tank second so the soapy gray water rinses the hose. Use the station’s rinse water for the hose and never your own freshwater hose, then close everything up and pull forward before reorganizing the bay. Tanks rinse cleaner when they are at least two-thirds full, so resist dumping a quarter tank just because a station is handy. Costs around the Willis area follow the usual Texas pattern: private campgrounds charge a modest flat fee like the $15 at Lake Conroe RV Campground, while public campgrounds fold dump access into camping or day-use fees. At public sites like Cagle Recreation Area, confirm station status on recreation.gov or by phone before arriving; facilities at federal campgrounds open and close with maintenance schedules.

Lake Conroe RV Campground by RJourney
Lake Conroe RV Campground sits at 12351 FM 830 Rd in Willis, TX, on a peninsula with water on 3 sides and 15 acres of private shoreline. For long-term RVers, the draw is the no-maximum-stay policy paired with a $525/month starting rate that includes the site, full hookups, WiFi, trash service, and lawn care. Several residents have lived on-site a year or more. Mature loblolly pines run through the property, a land bridge connects to a private island open to all guests, and Lake Conroe runs 22,000 acres and 157 miles of shoreline for fishing, boating, and paddling. The mix skews toward long-term residents, Houston-area contractors on multi-month projects, and snowbirds wintering somewhere warm. Nightly from $40, monthly from $525, full hookups, free WiFi, a pool, a hot tub, and 24/7 lake access.
Sites & Hookups
Every RV site has full hookups: water, sewer, and 30 or 50-amp electric. For long-term residents that matters most, because power runs reliably and utility service stays consistent month over month. Paved interior roads handle big Class A motorhomes and 5th wheels without mud after rainstorms or ruts from heavy rigs, which is exactly what you want when you live somewhere full-time. The peninsula layout puts most sites within line of sight of the water, and sites in the 40s look directly out over Lake Conroe. Each site holds up to 6 guests, with 4 included in the base rate and each extra at $5. Golf carts are permitted with a licensed driver. There is no tent camping, and there is no maximum stay, which is why long-term residents settle in: reliable power, consistent trash and lawn service, and a quiet community. A land bridge runs to a private island where you can walk out at sunset or fish from the shoreline.
What's On-Site
The 15 acres of private shoreline are the feature that anchors daily life here, with direct lake access for fishing, swimming, kayaking, canoeing, and paddleboarding 24 hours a day with a Texas fishing license. The pool runs 9 AM to dusk and the hot tub stays open year-round. Free WiFi covers the property, and long-term residents lean on the 24-hour laundry, ADA-accessible bathrooms, and 24-hour showers that run on your schedule rather than office hours. The on-site store carries RV supplies, fishing gear, and beverages, which saves a trip into town. The pavilion is free for cookouts, potlucks, and group gatherings, and it doubles as the social hub for monthly residents. A fitness room and big-screen TV lounge cover the indoor slate, and boat storage and RV storage are both available for guests who leave gear between trips. The freshwater fill station handles top-offs and the dump station handles departures for $15. Two notes on the property right now: the on-property boat ramp is currently too shallow to launch most boats, so the nearest usable public ramp is about a mile out, and the rear bathhouse has been removed while a replacement is built closer to the daily sites.
What Guests Say
4.2 stars across 257 Google reviews. For long-term residents, the steadier themes in the review pool are the ones that matter for daily life: reliable power, consistent trash and lawn service, and a quiet community. Tina (GM), Kim (front desk), and Francine (housekeeping) get named by guests, which is the hospitality signal you want when you live somewhere for months. Short-stay guests highlight the peninsula sites with line of sight to the lake; sites in the 40s draw the most photos. The land-bridge island is the standout that newer guests did not expect. The check-in question that runs ahead of all others: are the fish biting? Largemouth bass, channel catfish, crappie, bluegill, and hybrid striped bass all live in Lake Conroe, and spring through mid-fall is the peak window.
Other Campgrounds Near Willis, TX
<p>If you are camping at a public park nearby, plan your tank strategy ahead: both run water and electric at best, so a dump stop becomes part of the trip.</p>
Cagle Recreation Area (USFS)
A U.S. Forest Service campground inside Sam Houston National Forest with water and electric sites but no sewer connections, so you rely on a dump station. More wooded and rustic than a private park, with a public boat ramp, picnic areas, and swimming access. Stays are capped, so this is not a long-term base, but it is a solid shorter option. Sites fill on spring and fall weekends. Visit website.
Huntsville State Park
Huntsville State Park sits on Lake Raven with water and electric sites, hiking trails, and paddling access in a quieter state park setting. There are no full-hookup sites with sewer, and Texas State Parks cap consecutive nights, so it works for a nature-focused getaway rather than month-to-month living. A strong choice if you want trees and trails with basic hookups. Visit website.
Things to Do Once the Tanks Are Empty
Lake Conroe’s 22,000 acres give long-term residents room to spread out. Kayaks, canoes, and paddleboards launch right from the park shoreline, and the quieter coves and creek arms around the peninsula stay sheltered in the morning before powerboat traffic picks up. The fishing never stops with the seasons: spring spawning bass in the shallows, summer catfish best at night, fall bass as water cools, and winter crappie when you find the right depth. For trailered boats, the nearest usable public ramp is about a mile from the park, and on-site boat storage means you keep the boat here and trailer the short distance on launch days.
Sam Houston National Forest starts just east of the lake and covers more than 163,000 acres. The Lone Star Hiking Trail runs 129 miles through it, the longest continuously marked footpath in Texas, and day hikers can tackle shorter segments. The forest is also open for mountain biking and horseback riding, so for residents living here full-time, hiking and wildlife watching are always available without a long drive. Historic downtown Conroe is 15 minutes south with a growing restaurant and brewery scene, art galleries, and live music at the Crighton Theatre.
The Woodlands is 25 minutes south with shopping at Market Street, dining, and concerts at Cynthia Woods Mitchell Pavilion. Houston is 50 to 60 minutes for Space Center Houston, the Museum District, and the zoo. For long-term residents, the same corridor handles practical logistics: H-E-B, Walmart, and Kroger are 15 minutes south in Conroe, HCA Houston Healthcare Conroe is a full-service hospital 15 minutes out, and George Bush Intercontinental Airport is 45 to 50 minutes when family visits.
Lake Conroe Season by Season
Spring (March through May)
The best stretch of the year on the lake. Temperatures sit in the 70s and 80s, bass and crappie fishing heats up as the water warms, and wildflowers bloom in Sam Houston National Forest. For long-term residents the weather is mild, but East Texas humidity starts climbing, so run a dehumidifier inside the rig to keep mold and mildew in check.
Summer (June through September)
Hot and humid, with highs in the mid-90s and heat index values above 100. If your rig runs two AC units, book a 50-amp site; running both on 30-amp will trip breakers. Lake activity peaks with boats and swimmers on weekends, and the pool and hot tub get heavy use. Mosquitoes are active at dawn and dusk near standing water.
Fall (October through November)
Temperatures drop into the 60s and 70s and fall bass fishing is some of the best on the lake as water cools. This is when snowbirds start arriving for the winter, so the long-term community grows. The Texas Renaissance Festival runs weekends through this stretch about 25 minutes away; verify current dates before planning around it.
Winter (December through February)
Mild by national standards. Lows dip into the 40s and highs stay in the 50s and 60s most days, warm enough to skip winterizing your rig. Lake traffic drops off, giving residents quieter water for fishing and kayaking. This is peak season for the long-term and snowbird community, and the $525 monthly rate makes an extended winter stay affordable.
Practical Tips for Dumping Tanks Near Willis
Black tanks rinse cleaner when they are at least two-thirds full, so resist dumping every day. At $15 per use at the park's station, waiting also saves money, and guests on full hookup sites can simply leave the black valve closed until departure.
Disposable gloves, a clear sewer elbow, and a dedicated rinse hose (never your freshwater hose) make every dump faster and cleaner. The on-site store carries RV supplies if something tears mid-trip.
Lake Conroe RV Campground does not sell propane on-site. Fill up at a hardware store or gas station in Willis or Conroe. Long-term residents typically keep a spare tank so they do not run out mid-week.
East Texas humidity runs high from May through October. Run a dehumidifier inside your rig to prevent mold and mildew, and keep seals and caulking maintained to stop moisture intrusion.
The on-property ramp is currently too shallow to launch most boats. The nearest usable public ramp is about a mile away, and on-site boat storage means you can keep your boat at the park and trailer the short distance on launch days.
Frequently Asked Questions
Where is the nearest RV dump station near Willis, TX?
Lake Conroe RV Campground at 12351 FM 830 Rd in Willis runs a dump station for $15 per use, with a freshwater fill station on the same property. It sits just west of I-45 on the lake’s north shore, which makes it a practical stop for travelers heading up or down the Houston-Dallas corridor.
How much does it cost to dump RV tanks near Willis?
The dump station at Lake Conroe RV Campground costs $15 per use. Public campgrounds in the area fold dump access into their camping or day-use fees, which vary by site. Guests staying at the park itself rarely pay at all, since every site includes full sewer hookups.
Does Lake Conroe RV Campground have a dump station?
Yes. The park has an on-site dump station for $15 and a freshwater fill station for potable top-offs. Check in at the office or call (936) 256-3268 to confirm access hours before arriving. The on-site store also carries RV supplies if your sewer hose or fittings need replacing.
Do I need a dump station if my site has full hookups?
Rarely. Full hookups include a sewer connection at your site, so gray and black tanks drain right where you are parked. Every site at Lake Conroe RV Campground works this way. The dump station mostly serves travelers passing through and campers arriving from partial-hookup campgrounds nearby.
Is there fresh water available after dumping?
Yes. Lake Conroe RV Campground has a dedicated freshwater fill station separate from the dump station, so you can empty tanks and top off potable water in one stop. Use your own drinking-water hose for the fill and the station’s rinse water for cleanup, never the reverse.
Do the public campgrounds near Willis have dump stations?
Cagle Recreation Area and Huntsville State Park both run water and electric sites without sewer, so their campers depend on dump facilities. Station availability at public campgrounds changes with maintenance schedules, so confirm current status on recreation.gov or the Texas State Parks site before arriving with full tanks.
