Before You Go · Safety
Staying safe in the canyon
The Frio is gentle most days and powerful on the wrong one. A little canyon sense keeps the weekend joyful.
The Heat
Water, shade, and pacing yourself
September in the Hill Country still hits the high 90s. Heat is the most common reason people need our first-aid tent — so drink more than you think you need, find shade in the hottest part of the afternoon, and watch your group for dizziness or a headache. Free water-refill stations are at the info tent, the food court, and the river.
The River
Respecting the Frio
- Swim only at the marked access points. The lifeguarded gravel entry is staffed 10 AM–6 PM; the shallows are for small kids and have no lifeguard.
- The water is spring-fed and cold — ease in, and know that cold water tires you faster than you expect.
- The riverbed is slick limestone. Water shoes save ankles.
- Watch children at all times. The current is gentle until it isn’t, and a calm-looking river can move.
The Sky
Sun & sudden weather
Sunburn sneaks up near reflective water — hat, sunscreen, reapply. The canyon’s one serious hazard is flash flooding: heavy rain upstream can raise the river fast, even under blue sky here. If officials or staff call for it, move away from the water immediately and follow directions. We’ll post live updates at the info tent and on Instagram.

The Wild
Sharing the canyon
You’re a guest in a living place. Give wildlife room, don’t feed anything, shake out shoes and towels (scorpions like the shade), and stay on trails to protect both the plants and your footing. Snakes want nothing to do with you — watch where you put hands and feet among the rocks, and you’ll likely never see one.
If You Need Help
First aid & lost-and-found
The first-aid station is staffed on the main grounds — look for the cross, or ask any volunteer. Find it on the map → In a real emergency, tell the nearest staff member; we have a direct line to county responders.
Lost-and-found and the lost-child desk are both at the welcome tent. Pick up a free wristband for kids when you arrive and write your phone number on it — it’s the fastest way to reunite a family in a crowd.
Leaving It Better
Leave no trace
Pack out what you pack in, use the marked bins and recycling, and keep everything but footprints out of the river. This canyon has fed and sheltered people for thousands of years. Let’s hand it on the way we found it.
