Part 1:

Cuevas del Indios (Indian Caves) of Arecibo is a must see site for your Puerto Rican adventure.

An easy-to-find natural wonder, with a simple $2 fee for parking. Bring some sunscreen and your camera, because you won't want to miss any part of this.

Begin your hike up some sharp and spiky cliff sides (no worries, I was able to do it all in sandals.. in case you happen to come ill prepared).

Work your way up to the top of the cliff side and enjoy the fantastic view below. Ocean spray from the massive waves breaking against the side of the rocks will cool you off with a little salty mist. Dare to look over the edge to see a landscape of arches and tunnels, burrowed below your feet.

Climb down into the rocks to find a wonderful - and surprisingly well preserved - variety of Taino Indian petroglyphs. A small climb down a somewhat sturdy, handmade ladder lands you at the base of the cave with stone carved images surrounding you.

Now is your chance to experience some history. Wander through the smaller tunnels, listen to the ocean making its way inside the cave with every massive wave crashing outside.

Ancient history of a lost people.
