The Nauyaca Falls are an incredible sight. A jungle river falls hundreds of feet in a two-tiered cascade into a blue lagoon.
Swimming in the cool, clean pool of water is like taking a dip in Paradise. The Falls can be reached by horseback or jungle hike. Don Lulu offers a full-day guided horseback adventure out to the falls Breakfast and lunch are included in the package. Guests should provide their own transportation to and from Don Lulu's. Alternately, from the town of San Salvador, a few miles away from the resort, there is a self-guided, well- marked hiking trail through farmland and forest out to the Falls.
The hike takes about 3 hours round trip and is moderately difficult on the ascending return. The local "soda" sells the guide map for $2. The Diamante Falls are among the tallest in Costa Rica and can be reached by guided hikes to their base in the valley near San Cristobal. The cliffside can be climbed and repelled by a series of ropes in a guided adventure ponsored by the owners of the property near the base of the falls. They even offer lunch inside a cave behind the falls!
the 4km hike to the waterfall starts after crossing over the bridge and passing through the jungle. The trail is well-maintained, and during the dry season (when we went) it was relatively clean. After a heavy rain, the trail does become very muddy so you might want to bring shoes you don’t mind getting dirty. While some spots are shady, there are good portions that leave you exposed to the sun.
We recommend you bring sunscreen and lots of water, too.
Up the trail a little further is the entrance gate where you will need to show your wristband to the guard. Just a few hundred meters after the gate, you will have the option to visit the upper or the lower falls. While both are spectacular and worth a visit, the lower falls are the larger of the two and have a pool that is safe to jump and swim in.
