Brace for a technical, high-adrenaline Class IV run through the narrow canyon of Río Naranjo, just northeast of Quepos. Expect tight drops, fossil-lined walls, local fruit snacks at takeout, and a half-day guided expedition operating primarily in the dry season.
More ways to explore the area's outdoor wonders
The canyon narrows, walls close in and the Río Naranjo pushes you like a natural conveyor — cold, fast, and unforgiving in the best way. You launch from a rocky lip, paddles chattering, and for the next few kilometers the river alternates between surging slides, tight boofs and short, technical drops that demand quick responses.

Hydrate before launch
Drink water and use electrolyte tablets — you’ll work hard paddling and the tropical heat can dehydrate quickly.

Wear closed-toe river shoes with good grip; loose sandals will come off in turbulent sections.
Stash electronics in a dry bag
Phones and cameras should be in a proper dry bag or left behind; river swims are possible and recovery can be tricky in the canyon.
