The waterfall is fed by the Río La Paz. There is parking for visitors right next to it.

A lovely little area with benches and tables for a picnic, partly hidden in the forest. If you're lucky, you can spot hummingbirds or coatis here.

This work was made by the Costa Rican artist Leda Astorga in 1999. She is internationally renowned for her artistic ability, creativity and the expression of her work. The work responds to the recovery plan of public spaces, of history and identity of Alajuela. It is being carried by the municipality, to make clear the spirit of friendship, joy and peaceful coexistence.

A beautiful place, but said to be one of the more dangerous places in the city after sunset.
