>>636941Cerro Chirripo in Costa Rica is amazing. It's very physically challenging but you pass through 5 distinct ecosystems, tons of interesting animals (wild parakeets, lizards, sasquatch, etc...). The summit is something of a hand-over-hand scramble and on the rare clear day you can see the Pacific and Gulf of Mexico. I wasn't that lucky but it was still an amazing adventure.
Don't go in the rainy season since the trail turns into a river of mud
