This was a pleasant surprise. Half way through our birdwatching river float we pulled to the side of the river and hiked about 1/2 mile. In 1994 a flood uncovered these petroglyphs. Our guide produced a guide book and proceeded to interprete some carving. It way way tooo hot to hike to see the rest and we will return during a cooler time of year to do so.
We arranged this tour through the front desk at our hotel. A truck arrived athe appointed time towing a custum panga (plastic chairs attached to the bottom f the boat). These very nice and friendly poeple launched us with our guide at he river. Our guide was a very nice El Fuerte born man armed with binoculars and bird books. He spoke English and was very knowledgeable about the different birds. we saw close to 15 different types. Since in was a very warm day (think swelter) he pulled over to the side of the river to allow us to swim.
..........that mouthful is just the dam outside of town. It's depicted on the mural painting in the civic building.
We got a ride from some locals my buddy chatted up. I don't know if the bus goes there, but there's always the taxi and it's about a thirty minute ride.
Besides the lakes and the dam, there is wildlife.
