See both an active volcano and one of the world’s most acidic lakes at Poás Volcano in central Costa Rica. This stratovolcano has erupted 40 times since 1828, the most recent in 2017. Two crater lakes near the summit are especially unique, made acidic due to volcanic activity and sulfur. The national park in which the volcano lies is open, with trails opening and closing depending on detected geothermal activity. © Claude Gariepy | Dreamstime.com

Near Quito, Ecuador, is Pichincha, a stratovolcano rising nearly 16,000 feet above ground. Spanning two peaks, experienced hikers can attempt acclimatization climbs. The last eruption occurred in 2000. While fewer people ascend this volcano, many enjoy its grandeur from nearby locations like TelefériQo, on the western side of Quito. Fun fact: An interestingly named orchid, Dracula vampira, can be found on the volcano. © Sl Photography | Dreamstime.com

Volcanoes National Park, on the Big Island of Hawai’i, is home to not one but two active volcanoes: Kīlauea and Mauna Loa, the former one of the world’s most active volcanoes, the latter the world’s largest shield volcano. The park is open to visitors and also home to rare flora and fauna. Currently, the park is mostly open, with some roads and trails still closed from the most recent eruptions. © Jocrebbin | Dreamstime.com
