Start early for light and wildlife
Pickup is usually early; morning light enhances the river’s blue and increases chances of bird and sloth sightings.

Pack a reusable water bottle
Guides supply bottled water but refillable bottles cut waste; hydrate before and during the trail sections.
Respect wildlife at the sanctuary
Follow guide instructions—no flash photography or touching animals—to support conservation and safety.
Sturdy hiking shoes
Grip and ankle support for rooty, muddy trails and wet rocks at viewpoints.
Light rain jacket
Quick showers are common; a lightweight waterproof layer keeps you comfortable without overheating.
