Full Description ?
This tour begins in San Juan, heading north into the limestone karst zone where you’ll first arrive at Cueva del Indio. Here you’ll traverse the iconic “7-arches” rock formation over the ocean, then step into the sea cave where Taíno — the island’s original inhabitants — left hundreds of petroglyphs on the cavern walls.
Next you’ll continue to Charco Azul Canyon, a hidden natural sanctuary where the river has chiseled out caves and rock pools. You’ll hike down into the canyon, cross the river, swim through grottoes, and may even cliff-jump into a crystalline turquoise pool.
Throughout the day you’ll be guided by local experts who bring together nature, history and adventure. Fitness is required — the terrain includes hiking, water crossings and climbing in some sections — but the reward is a dynamic blend of culture and wild scenery
