Braulio Carillo National Park
It's mostly wet, less rain in March and April. Be prepared for afternoon showers. It can be foggy in the morning depending on the altitude.
We made a stop for lunch at Quebrada Gonzales station on the way to the coast to Puerto Viejo. Due to the highway it's an easy access to this breathtaking forest. It was not planed to do, the nice ranger made us curious for hiking through a part of it. We were the only ones in the park. It was amazing that we could enjoy the birdsong and forest in silence although it is close to the highway.
