What to expect
You'll kit up in wetsuits and neoprene socks before entering the streambed. Expect plenty of water contact—wading, swimming through pools, sliding down natural chutes worn smooth by water. The canyon requires scrambling over boulders and careful footwork on wet stone. Your guide will show you each obstacle beforehand so you understand what's coming. You're not racing; pacing gives everyone time to find their rhythm. Some sections involve brief rappels or deeper water; there's a siphon passage you can skip if it doesn't appeal to you.
