Take the main highway from Liberia towards San Jose-zero your trip odometer at the main intersection in Liberia.  At 23.5 kilometers there is a small sign on the right, take the dirt road.  You will be asked to make a voluntary contribution to the local school and you will get a reciept.  Drive another 5 mins, park and hike down about 100 easy yards (water shoes not flipflops) and you will be astounded by a 70 ft high by about 70 foot wide waterfall, with a pool and a little beach in front.  Plunge in and enjoy, notice the fool's gold flakes in the water.  Bring your own refreshements as there is usually nothing there.

From the beach, look left across the stream-at the concrete pole there is a path to the top for a different view--not for the faint hearted or those afraid of snakes....

Fantastic half day kind trip!
