Guadalupe River State Park is about 13 miles east of Boerne and roughly 30 minutes from downtown San Antonio, with 1,900 acres, about four miles of river frontage, and a $7 day-use entry for adults. Kids 12 and under are free. Swim, tube, paddle, or hike 13 miles of trails, here is what to know before you go.
The numbers at a glance
Guadalupe River State Park covers about 1,900 acres along the spring-fed Guadalupe River, roughly 13 miles east of Boerne off State Highway 46 on Park Road 31, according to Texas Parks and Wildlife and the City of Boerne. From San Antonio it is about 30 miles north, a half hour in the car.
Day-use entry is $7 per adult, ages 13 and up, with children 12 and under free. Inside you get about four miles of river frontage, roughly 13 miles of hiking, biking, and equestrian trails, and a 5-mile paddling trail on the water, per the TPWD paddling trails map.
A day on the river
The river is the whole show. Clear and cool, it runs over limestone shelves between bald cypress and bluffs, with wide sandbars for spreading out. Swimming, tubing, canoeing, kayaking, and fishing all happen in the same stretch, and on a summer day the current does most of the work on a tube.
One honest note: the river can rise fast after upstream storms, and the park posts water conditions at the gate. When it is clear, this is the best free-flowing swim hole within a short drive of Boerne.
Trails and quiet corners
Beyond the water, the park holds about 13 miles of trails across limestone hills, oak and juniper woodland, and grassland, good for hiking, mountain biking, and horseback riding. Camping and picnicking run along the river, and the birding is worth the walk all on its own. TPWD
Next door, the Honey Creek State Natural Area opens by guided tour, a separate chance at the quiet side of the same watershed, with a spring creek and old-growth woodland.
Plan around the details
A few details make the day smooth: wear river shoes, because the limestone ledges are slick; pack water and sun protection, because shade is patchy; and arrive early on summer weekends, because the river day-use lot fills on hot Saturdays.
The math is friendly for families, $7 per adult and free for kids 12 and under, with camping available if you want to turn one day into two.
Pair it with Boerne
Thirteen miles west is the town that makes this park so convenient. Boerne's Hill Country Mile, Cibolo Nature Center, and Boerne City Lake put a full weekend together in one small circle.
