Summer in Concan starts at a low crossing on the Frio, where the river runs spring-fed and cold over clear gravel and the first tube of the morning slips into the current. The float drifts under bald cypress from one crossing to the next and carries everyone back to camp before lunch. On a good day nobody starts an engine, and the afternoon belongs to a nap in the shade before somebody lights the grill.
That rhythm is why families bring a motorhome or a towable to Concan and leave it parked for the week. River season runs through spring and summer, and in the hot months a full-hookup site keeps the air conditioning going while the kids dry off and the fridge holds a week of groceries. The same site works as a base for Lost Maples, a drive up the canyon road once the maples turn in the fall.
The Frio River resorts in Concan
Riverbend on the Frio has private river access, so the first swim of the day starts inside the campground. For a week in a motorhome, the 50-amp full-hookup Hilltop sites carry the air conditioning and the tanks without a run to the dump station. The smaller sites need a closer look: as of September 2026 the 30-amp Hilltop sites are capped at 25 and 34 feet and the covered Premium Pavilion sites have a 12-foot height limit, so match the rig's length and roof height to the site before booking. If those limits rule out the motorhome and it's just the two of you, a rig from the Texas campervan listings is the easier fit.
Camp Riverview puts its mixed-use water-and-electric sites under 100 feet from the river, close enough that the tubes can dry on the bank by the picnic table. It also runs full-hookup sites at 20, 30 and 50 amps, plus a Family Camp built for a small group of RVs, which is how a reunion or two families traveling together end up camped side by side.
Parkview Riverside RV Resort faces Garner State Park from the other bank of the Frio, and it's the resort to look at for the longest motorhomes. Every site has 20, 30 and 50-amp service, and the resort's FAQ says its sites are long enough for large units with slide-outs. Garner's own loops and its summer dance are on the Garner State Park RV page.
Whichever resort holds the week, make it the first night too, and get there with daylight left. Riverbend asks first-timers to arrive before dark, which is sound advice anywhere on the river when the last job of the drive is backing a long rig into a site you've never seen.
Lost Maples in the fall, up the canyon road
Up the canyon from Concan, the bigtooth maples at Lost Maples turn red and orange against pale limestone walls through October and November, and the canyon trail fills with people who drove across Texas to walk under them. Plenty of families make it a fall habit.
A rig can stay in the park or come up for the day. Lost Maples has 30-amp water-and-electric sites with back-in RV parking, and Texas Parks and Wildlife publishes no length cap for them, so call the park before bringing a long motorhome. The other way keeps the full hookups in Concan and makes Lost Maples a day trip up the canyon road and back.
Book ahead either way. Texas Parks and Wildlife says the park reaches capacity daily in October and November and takes reservations online, and there's no cell service at the park, so save the confirmation before you leave town. For a smaller rig coming out of San Antonio, the San Antonio campervan page covers Lost Maples as an overnight.
