The Taulabé caves make an easy and interesting stop off the CA-5 at km 140. More than 12km of tunnels and caverns have so far been explored, but only 400m have paths and lighting. You can walk through the caves on your own, but local guides also hang around. The caves can be slippery, so make sure you wear suitable shoes. All local buses running along the CA-5 will drop you off here; it’s also easy to catch a bus on to La Guama for the lake or back to the junction at Siguatepeque for connections to the west.
