There's a spectacular Petroglyph not far from town; if you do Da Flying Frog canopy tour, ask to be taken by. Otherwise, walk toward Rivas, passing the Texaco station, and make a left after the bridge. Pass a school and then a gate on your right. Continue to the old farmhouse; if anyone's around, you should ask permission to cross the land.
Otherwise, follow the irrigation pipes to the river, where you'll find the stone, showing an enormous and elaborate hunting scene carved perhaps 1500 years ago. If you continue upstream, you'll come to a small waterfall.
