Walk into Tenorio’s rainforest to see Rio Celeste’s surreal blue where two rivers merge, then visit the Bride’s Veil waterfall and nearby hot springs. This full‑day hike blends easy boardwalks and muddy climbs with volcanic geology and sharp jungle wildlife encounters.
More ways to explore the area's outdoor wonders
Mist rises off jungle leaves as you step onto the Tenorio trailhead before dawn; the air is damp, layered with moss and the distant rumble of a volcano. The path threads through secondary and cloud forest, drops to the turquoise shock of Los Teñideros where two rivers meet, then climbs to the Bride’s Veil waterfall — a raw, electric blue slashing through green.

Start early to beat the clouds
Morning light often coincides with clearer blue water and fewer people; aim to arrive at the park entrance at opening or join an early pickup.
Good traction matters
Trails get slippery after rain—wear closed-toe hiking shoes with a grippy sole rather than flip-flops or sandals.
Respect the blue — no swimming
Swimming or using soap in the river alters the mineral balance that creates the color; enjoy photos from the viewpoints only.
Pack light, pack smart
Bring a waterproof camera case, 1–2 liters of water, insect repellent, and a small towel for damp conditions and hot-spring stops.
Sturdy hiking shoes
Grip and ankle support for muddy roots, steps, and rock sections on the trail.
Rain jacket or poncho
Protects you in tropical downpours common in the wet season and keeps layers dry.
summer
Reusable water bottle (1–2 L)
Hydration for several hours of hiking; water refills may not be available on the trail.
Waterproof phone/camera case
Keeps electronics safe from spray at the waterfall and sudden rain showers.
