Cabo Blanco is a nice day away from Montezuma. The National Park is really quiet (not that touristy when I was there at least) and is a good hike. Obviously bring good shoes as the path has a few steep and narrow parts.

It was tide when we got there and the sea was a lot rougher than I had imagined - not suitable for swimming but the bamboo surroundings and beautiful coastal views are great. Also, spotted some monkeys along the way.

During low tide you can walk to the nearby cemetery island in Cabuya, which seems interesting! (we weren't able to do this)
