This impressive environmental museum has several vast galleries with interactive exhibits on local flora and fauna, climate change, local geology and environmental impact studies as well as basket-weaving video demonstrations. All information is in Spanish, but there's enough here to keep nonspeakers interested, including a river-fish aquarium and an outdoor section with examples of different wetland environments and sustainable technologies. Bus 7 stops outside. It was closed for renovation when we visited but should be open by the time you read this.
