Palo Verde National Park is located in Guanacaste in northwest Costa Rica. It surrounds the Tempisque River, where there is an abundance of birds and other wildlife. We took a boat ride on the river through the forest, which was booked through Hacienda El Viejo Wetlands. Our knowledgeable guide pointed out tons of animals, including herons, crocodiles, lizards, monkeys, and bats. It was nice to get away from the heat by being near the water.
