Cataratas Nauyaca information
This center, owned and operated by a Costa Rican family, is home to the coast's most impressive waterfalls, which cascade through a protected reserve of both primary and secondary forest. The family runs horseback-riding tours to the falls (reservations required; Dominical pickup available), where visitors can swim in the inviting natural pools. Alternatively, you can hike to the falls in one hour or so if you're in decent shape.
The center is located 10km up the road from Dominical to San Isidro.
