A community-run nature reserve designed to protect the town's water supplies, this innovative project has a number of hikes marked out, including the four-hour Ruta de los Chorros trail that takes you past three 50m waterfalls (one of which you can see from town) to a mirador (lookout point) with views clear to the Pacific Ocean.
You can arrange guides at the Gabinete de Turismo in the alcaldía building.
