RV Rental Near Guadalupe River State Park (Spring Branch) in San Marcos, TX

Every spring I get the same call, usually around late February: “We want to float the Guadalupe in April — can you get a rig into the state park before the sites book out?” My answer is always yes, but I follow it up fast with this: reserve your campsite on the Texas Parks & Wildlife reservation system the same day you call me, because the electric hookup loops at Guadalupe River State Park fill weeks out once the Hill Country weather turns warm. I’ve delivered trailers out to Spring Branch enough times to know that the park’s site availability is almost always the chokepoint, not the RV itself.

What I love about doing deliveries to Guadalupe River State Park is that it genuinely earns the “set up camp and forget the logistics” promise. The park sits on FM 3351 off US-281 north of Spring Branch — about 45 minutes northwest of San Marcos when I’m running I-35 north and cutting over on US-281. I back the rig in, level it, run the hookups, and walk you through the basics before I leave. By the time you’re cracking a cold drink, the cypress trees are already throwing shade over the river and you don’t have to think about anything except where to drop your kayak.

What Camping at Guadalupe River State Park Actually Looks Like

The park sits on a gorgeous bend of the Guadalupe River in Kendall County, and the campground is divided into a handful of different loops and site types. There are water-and-electric sites that can handle a full-size travel trailer or a smaller Class C motorhome without a problem, and there are also primitive walk-in tent sites if any of your group wants to rough it. When I deliver, I’m almost always going into the developed loops — the pull-through and back-in sites there have 30-amp service, and a few offer 50-amp, which matters if you’re in a larger rig with a residential fridge or dual air conditioners running in July.

The one thing I always flag first-timers on: the roads inside the park are paved but the turns between certain loops can feel tighter than you’d expect when you’re towing. I’ve learned to take my time and swing wide at those junctions. If you’re in a longer trailer — say, 30 feet or more — let me know when you book and I’ll factor that into the size recommendation so we’re not wrestling a rig into a site that’s technically long enough but operationally miserable. Also, a Texas State Parks Pass covers day-use entry for your guests coming to visit; overnight campers pay the nightly campsite fee on top of that, so budget accordingly.

The Best Time of Year to Rent an RV Here (From Someone Who Delivers Year-Round)

Spring — March through mid-May — is the sweet spot. The Guadalupe is running full and clear, the bluebonnets are doing their thing along US-281, daytime temps are in the 70s, and evenings cool down enough that you barely need the AC. That’s the window families and couples both love, and it’s when I stay the busiest with this park specifically.

Summer is busy for a different reason: tubing and swimming. June and July at Guadalupe River State Park mean the river is warm, the days are long, and you will be sharing the water with a lot of people. It’s still a great trip, but the heat is real — central Texas July afternoons regularly push past 100°F. If you’re going in summer, I strongly recommend a rig with a properly sized air conditioner. Ask me about that when you call; it’s one of those details that makes or breaks a July trip.

Fall — late September through November — is underrated at this park. The crowds thin out dramatically after Labor Day, the water is still warm enough to swim well into October, and the Hill Country light in that season is something else. I’ve delivered rigs out here in October and November for couples who specifically want the quiet, and they always come back telling me it was better than they expected.

Winter camping is genuinely possible here and the park stays open, but the Texas Hill Country can drop into the 20s overnight between December and February. If you’re planning a winter trip, we need to talk about whether your rental unit has adequate insulation and a furnace that can keep up with those temps. It’s doable — I just want you going in with realistic expectations rather than waking up to frozen pipes.

How I Handle Delivery and Setup From San Marcos

My delivery route from San Marcos to Guadalupe River State Park runs northwest — I pick up I-35 toward New Braunfels, then head north on US-281 through Blanco County and into Spring Branch. Door to campsite it’s typically around 45 to 50 minutes depending on traffic around the New Braunfels interchange, which can back up on summer Friday afternoons. I plan my deliveries accordingly, and I’ll usually give you a one-hour arrival window so you’re not standing at the park gate wondering where I am.

When I arrive I do the full setup: I park and level the unit, connect water, run the electrical hookup, extend the awning if conditions are calm, and do a complete walkthrough with whoever is at the site. I show you how the water heater works, how to run the AC or furnace, where the circuit breakers are, and what to do if something trips. That walkthrough matters — I’d rather spend 20 minutes with you at setup than get a panicked call at 10 p.m. about the water heater pilot. If you’ve never stayed in an RV before, just tell me. I slow down for first-timers and I don’t rush the walkthrough.

At pickup, I come back to the site, do a quick inspection, break down the hookups, and haul everything out. You don’t have to drive anything or worry about returning a vehicle. That’s the whole point of the delivery model — you fly into Austin-Bergstrom or drive down from wherever, get to the park, and the rig is already there waiting.

What to Do While You’re Based at the Park

The river is the main attraction, and you can swim and wade from the park itself — there are designated access points and the cedar-lined banks are genuinely beautiful. If you want a guided paddling experience or a tube float, outfitters in the area can set that up. Beyond the park boundary, here’s what I tell guests to consider working into the trip:

• Canyon Lake — about 25 minutes south on US-281 and TX-46. Boating, fishing, and a completely different water experience. The Corps of Engineers parks around the lake have their own campgrounds if you need overflow space for extra guests.
• Devil’s Backbone Scenic Drive (TX-32) — one of the best drives in the entire Hill Country, running between Wimberley and Blanco. Take it on a clear morning and you’ll understand why people move out here. The views off the ridge looking south toward the Blanco River valley are not something you can replicate anywhere else in Texas.
• Wimberley — about 30 minutes southeast on FM 3351 and TX-12. Blue Hole Regional Park has a spring-fed swimming hole that’s genuinely worth a half-day, and Wimberley Square has good food and local shops. It gets crowded on summer weekends, so go on a weekday morning if you can.
• Blanco State Park — about 20 minutes west of the park on US-281. Another river park with tubing and fishing, and one of the more underrated small state parks in the system. If the Guadalupe is high or running fast, Blanco can be a calmer alternative for families with younger kids.
• Lockhart BBQ Trail — less than an hour east on US-281 and US-183. Kreuz Market, Smitty’s, Black’s — if you’re on a Hill Country camping trip and you don’t drive to Lockhart for brisket at least once, I genuinely don’t know what to tell you. It’s worth the drive.
• San Marcos — about 45 minutes southeast. If you need supplies, groceries, or a day on the San Marcos River, the city is close enough for an easy day trip from the park. Texas State’s campus area has good food, and San Marcos Premium Outlets is there if anyone in your group wants to shop.

Booking the Site and Booking the RV: How to Line Them Up

Here’s the sequence I walk every customer through. First, go to the Texas Parks & Wildlife reservation site and lock in your campsite at Guadalupe River State Park. Note your exact site number and what hookups it has — 30-amp, 50-amp, pull-through or back-in — and have that information ready when you call or email me. That detail directly determines which unit I assign to your trip. A 50-amp site unlocks the larger, more comfortable rigs. A 30-amp site is still fully functional, it just narrows the options slightly at the larger end of the fleet.

Once you have the site confirmation, call me at 512-402-3595 or email [email protected]. I’ll confirm availability, talk through the unit that fits your site and your group size, and give you a clear picture of the delivery window and what to expect on arrival day. I’d rather have a 10-minute conversation up front than sort out a mismatch the morning of delivery.

For spring and holiday weekends — specifically spring break in March, Easter weekend, Memorial Day, and Fourth of July — I’d tell you to reach out to me at least four to six weeks out. The park sites go fast, and my calendar fills up right behind them. Fall and winter dates are more forgiving, but earlier is always better.

Other Hill Country Campgrounds Worth Knowing

Guadalupe River State Park is my first recommendation for this corner of the Hill Country, but it’s not the only option. If the park is full when you check — and it does fill, especially on holiday weekends — I also do regular deliveries to Blanco State Park in Blanco and to Canyon Lake Thousand Trails and Comal Park around Canyon Lake. Palmetto State Park down in Luling is a different landscape entirely — subtropical palmetto palms along the San Marcos River — and it’s an interesting option if you want something more unusual. Closer to town, Pecan Park Riverside Cabins & RV Park in San Marcos is a full-hookup option right on the river if you want to stay in the city.

Each of those campgrounds has its own site layout quirks and hookup configurations, and I’ve learned them all through repeat deliveries. When you tell me where you’re camping, I can give you a straight answer about what the site will accommodate — not a guess based on a campground website photo, but actual firsthand knowledge from having backed a trailer into those loops myself.
