Wear water-friendly footwear
Bring sturdy water shoes or sandals with a heel strap to protect feet from rocks and provide grip when entering/exiting the river.
Cover up from the sun
Use broad-spectrum sunscreen and a long-sleeve rash guard—sun is strong during the midday return, and reflections from the water intensify exposure.
Bring insect repellent
Mosquitoes are common along the banks—apply repellent before departure and reapply after the float if you plan to linger on shore.
Secure electronics in a dry bag
Phones and cameras should be stored in a waterproof pouch; you’ll want photos but the float is hands-free and occasionally wet.
Water shoes
Protect toes and provide traction when entering and exiting the river.
Dry bag or waterproof phone case
Keeps electronics and essentials dry during the float and transfer rides.
Reef-safe sunscreen
Protects skin from intense sun without harming local aquatic life.
Lightweight insect repellent
Reduces bites when on the riverbank or after the float.
