2. Galapagos Islands, Ecuador
The Galapagos are known for the endemic bird, reptile and plant life, but the dynamic volcanic topography is an equal drawing card. Over 70 eruptions from nine active volcanoes have occurred in the last 200 years alone, creating fresh new rippling landscapes and resulting flora/fauna variations that make this young island chain a living laboratory of evolution. La Cumbre on Isla Fernandina is the most active volcano in the archipelago, last spreading some lava love in 2009. Most accessible to visitors is Isabela’s Sierra Negra, which boasts the second largest volcanic caldera in the world. You might not see flowing lava (although it last erupted in 2005 so you never know) but you can hike around its lunar-like lava fields and see – and smell – it’s billowing thermal vents.
