Quick Overview

Castroville sits along the Medina River, where German and Alsatian heritage meets Texas Hill Country charm. This small town, known as the "Little Alsace of Texas," offers a peaceful escape from San Antonio's bustle just 25 miles to the east. Historic limestone buildings line the main streets, and the Medina River provides a cooling backdrop for summer camping.

The area features several motorhome campgrounds that cater to different camping styles. Both are paid facilities offering full service, with some free camping options available in the immediate area. Most parks here focus on providing reliable amenities rather than extensive recreational facilities, making them solid choices for travelers passing through or exploring the region.

From your campsite, you're positioned perfectly to explore Castroville's historic district on foot. The Landmark Inn State Historic Site offers guided tours of this 1840s frontier inn, while the Alsatian heritage shows up in local bakeries and restaurants. The Medina River winds through town, creating opportunities for kayaking and fishing right from some campsite locations. Day trips to San Antonio put you within reach of the River Walk and Alamo, while Bandera and the heart of Hill Country lie just 30 minutes west.

Full hookup travelers appreciate the reliable utilities and easy access to town amenities. Those seeking a more natural setting can explore nearby state parks for dry camping options. Budget-conscious RVers will find reasonable rates compared to San Antonio, though free camping requires venturing to surrounding public lands.

Spring and fall offer the most comfortable camping weather, with wildflowers blooming along river corridors in March and April. Summer brings heat but also river activities. Winter stays mild enough for comfortable camping, attracting snowbirds escaping colder climates.

Our listings below detail each campsite's specific amenities and seasonal availability to help you choose the right fit for your rig and travel style.

Traveling to Castroville by RV

US Highway 90 provides the main route into Castroville from both directions, offering an easy drive for RVs of all sizes. Coming from San Antonio, take I-35 south to Highway 90 west for a straight shot that avoids city traffic complications. The route from the west brings you through scenic Hill Country terrain with gentle rolling hills that won't challenge even larger motorhomes.

State Highway 471 connects Castroville to Bandera and the northern Hill Country, but this route includes some winding sections that require attention with longer rigs. Stick to Highway 90 for the most motorhome-friendly access. The town itself features wide streets that accommodate motorhome traffic without difficulty.

Fuel up in Castroville at the stations along Highway 90 before heading into more remote Hill Country areas. HEB grocery store on Highway 90 provides full provisioning for extended camping trips. The Walmart in nearby Hondo, about 15 minutes south, offers additional supplies and services.

RV-specific services are limited in town, so handle any maintenance needs in San Antonio before arriving. The closest motorhome dealership and repair facilities operate out of San Antonio's northwest side, about 30 minutes away via I-35 and Loop 1604.

Before You Go: RV Trip Essentials

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

Currently, a portion% of the area's several campgrounds offer free camping, while a portion% charge fees. This reflects the focus on full-service facilities rather than primitive camping.

Seasonal pricing stays relatively stable year-round, though expect slight increases during October's Oktoberfest celebration and spring Market Days events. Winter months often see the best deals as snowbird traffic hasn't yet peaked.

Groceries at the local HEB cost slightly less than San Antonio prices, while fuel runs about average for the region. The town's compact size means minimal driving once you're settled, helping stretch your fuel budget.
