You step off the minivan onto a red dirt carpark ringed by towering heliconias; the rainforest closes behind you like a wet, green wall. The trail into Tenorio Volcano National Park threads under a living roof of ficus and bamboo, and the river ahead seems to dare you to follow it until it suddenly becomes impossibly blue at Los Teñideros.

Start early
Morning light and lower visitor numbers improve visibility at Los Teñideros and make parking and photo opportunities easier.

Humidity and waterfall spray mean you'll appreciate a dry set for the return ride to La Fortuna.
No soap or swim products
Avoid confusing the park's delicate chemistry — don't swim with sunscreens or soaps in the river or lagoon areas.
Waterproof hiking shoes
Grip and waterproofing help on muddy rainforest trails and wet rock near the falls.
