Fall, from late September through November, offers similar conditions with smaller crowds. Summer days are hot outside, though the cavern itself stays cool year round, making tours a good midday escape.

This RV trailer was immaculate to begin with. Joe had it completely setup (water, electric, sewer, leveled) at the exact time we had agreed to. He went over all of the features of the trailer with me before departing and answered his phone whenever we had any questions. I'll definitely rent from Joe again and would recommend anyone in the Texas Hill Country to do the same with absolute confidence. Thanks Joe and Bekah!

This RV was awesome! Joseph and Bekah delivered it and set it up. They even made the bed, provided linens/towels, pots and pans, dishes, a coffee pot…. We are cooks and their knives are better than ours! We will rent this RV again!

We had an amazing time with this RV rental. Steve and Genna were amazing host.
Jason L. - Sep 2026
We had an incredible experience renting an RV for the F1 weekend in Austin. Communication was flawless from start to finish - they were friendly, responsive, and genuinely great to work with. They handled the entire setup and pickup, making the process completely seamless and stress-free. I would absolutely recommend renting from them and wouldn’t hesitate to book again. If you’re on the fence, don’t be, you're in great hands!

How to get to Longhorn Cavern State Park
The park sits in the Texas Hill Country near Burnet, about 60 miles (roughly 1 hour 15 minutes) northwest of Austin via US 183 and SH 29, and about 90 miles (around 2 hours) north of San Antonio via US 281. Access is via Park Road 4, a narrow, winding CCC-era parkway with tight curves and limited shoulders, so larger motorhomes and long trailers should drive slowly and watch for low-speed scenic traffic. The nearest major fly-and-rent airport is Austin-Bergstrom International Airport (AUS). There are no RV hookups inside the park, so most renters stay at private RV parks near Burnet, Marble Falls, or Inks Lake State Park and visit for the day.
