Secure footwear only
Wear water shoes or sandals with heel straps—flip-flops and crocs are not allowed and make stream crossings hazardous.
Bring a dry bag
Protect electronics and snacks; a small dry bag keeps camera gear safe during river re-entries and splash zones.
Start early
Morning launches typically mean calmer water, fewer boats, and cooler hiking conditions on the trail.
Watch river conditions
Tours cancel in heavy rain—high flows make crossings dangerous and increase bacterial contamination risk.
