Rivers to Reef: Six Days Through Costa Rica’s Rainforest, Rapids, and Pacific Light
From whitewater canyons to volcanic trails and Pacific sunsets—one compact, high-reward circuit through Costa Rica.
Dawn pads into San José soft and curious, the valley still wearing its night-cooled air as coffee steam curls like a trailhead ribbon. You step outside to a skyline edged in volcano silhouettes, the city murmuring awake, and the adventure already gathering itself at your feet. In Costa Rica, the environment does not sit politely in the frame. It leans in. The rainforest thrums like a heartbeat. Rivers shoulder past boulders as if they’ve got somewhere to be. The Pacific exhales at dusk and lets the day go in a spill of copper light. Over six days, this curated circuit—San José to the Pacuare River, on to La Fortuna and Arenal, then west to Jacó Beach—traces that living cadence from clouded uplands to salt-bright coast.
Trail Wisdom
Start Early, Move Smart
Morning departures beat heat, traffic, and afternoon showers. Wildlife is most active at first light, and river levels are typically more predictable early.
River Footwear Matters
Wear closed-toe water shoes or secure sandals with heel straps for the Pacuare—flip-flops get lost, and bare toes get bruised on slick rock.
Sun Strategy on the Coast
Reapply reef-safe SPF every two hours and add a long-sleeve UPF shirt for Jacó; tropical sun escalates faster than you think.
Respect the Rainforest
Keep 20–30 meters from wildlife, never feed animals, and stay on marked trails—your distance keeps both you and the creatures safe.

Conservation Note
The Pacuare watershed is a key wildlife corridor; stick to Leave No Trace principles, carry out all trash, and use reef-safe sunscreen to protect rivers and coastal ecosystems.
Arenal’s 1968 eruption reshaped the region, prompting evacuations and establishing the modern boundaries of Arenal Volcano National Park.
