Quick Overview

San Antonio is one of Texas's largest cities and a major crossroads for RVers traveling through the southern half of the state. Sanidumps lists several dump stations in the San Antonio area, with some free locations -- that's a portion% offering no-cost disposal and a portion% that charge a fee.

The metro area sprawls across Bexar County with motorhome-friendly infrastructure scattered along the I-35, I-10, and Loop 1604 corridors. Most service point options are on the north and east sides of the city, near the cluster of motorhome parks along I-35 North toward New Braunfels and along I-10 East toward Seguin. The south side near Lackland AFB also has facilities serving military RVers. The Randolph AFB area on the northeast side adds another cluster of motorhome-friendly resources for active duty and retired military.

San Antonio works well as a base camp for exploring the Texas Hill Country. Canyon Lake, New Braunfels, and Fredericksburg are all within easy reach, and many RVers stage their Hill Country trips from parks on the city's north side. Government Canyon State Natural Area on the far west side offers trails and day-use facilities, though motorhome camping there is limited. The San Antonio Missions National Historical Park, a UNESCO World Heritage Site stretching along the river south of downtown, is one of the city's most underappreciated attractions.

For RVers passing through on I-10 between Houston and El Paso, San Antonio is a natural midpoint stop. The city's service point network covers the main transit corridors well, and you won't have trouble finding a sanitary service point whether you're staying for a week to explore the Riverwalk or just overnighting on your way west. The convergence of I-10, I-35, and I-37 here means traffic from nearly every direction funnels through, and the motorhome service industry has grown to match that demand.

Traveling to San Antonio by RV

I-35 and I-10 are the primary interstate routes through San Antonio. I-35 runs north-south connecting Austin and Laredo, while I-10 runs east-west between Houston and El Paso. Loop 410 circles the inner city, and Loop 1604 forms the outer ring -- both handle large rigs but get congested during rush hours.

Traffic in San Antonio is manageable by major-city standards, but I-35 through the downtown corridor and the I-35/I-10 interchange are perpetual bottlenecks. If you're transiting through, I-410 bypasses the worst of it. Rush hour runs 7-9 AM and 4-7 PM on weekdays. Plan your moves outside these windows if you're driving anything over 30 feet.

Fuel and diesel are plentiful at every interstate exit. Texas diesel prices run below the national average, which is a nice break for motorhome drivers. Propane refills are available at numerous locations along the Loop 1604 corridor and at farm supply stores on the outskirts.

Explore the San Antonio Area

The downtown streets are narrow, parking is tight, and you'll regret bringing anything bigger than a car. The Pearl District north of downtown is another food and culture hub worth exploring on foot.

Buc-ee's in New Braunfels (about 30 miles northeast on I-35) is worth a stop for fuel, snacks, and clean restrooms. For Motorhome supplies, Camping World has a San Antonio location, and multiple motorhome dealerships along I-35 North can handle parts and service. H-E-B grocery stores are a Texas institution with excellent prices and fresh food departments. You'll find locations throughout the metro.

Summers in San Antonio are brutally hot -- triple-digit temps are common from June through September. Make sure your AC and electrical systems are up to the task before committing to a summer stay. The shoulder seasons of March-April and October-November offer the most comfortable weather for Motorhome touring. Cell coverage is excellent throughout the metro on all major carriers.
