Los Gemelos (Pit Craters)

Los Gemelos (The Twin Craters): A Geological Wonder in the Galápagos Highlands

Hidden in the lush highlands of Santa Cruz Island, the Los Gemelos, or Twin Craters, are one of the most fascinating geological formations in the Galápagos. Despite their name, these massive sinkholes aren’t volcanic craters but rather collapsed magma chambers formed over centuries. Surrounded by dense scalesia forests and rich biodiversity, Los Gemelos is the perfect stop for nature lovers and geology enthusiasts alike.

🌋 Why Visit Los Gemelos?

• Marvel at two enormous sinkholes formed naturally through geological processes unique to volcanic islands.
• Walk through rare scalesia forests, often called the “Galápagos cloud forest,” home to endemic plant and bird species.
• Spot iconic Galápagos wildlife including the woodpecker finch, short-eared owls, and vibrant Darwin’s finches.
• Enjoy peaceful hiking trails surrounded by dramatic landscapes and cool, refreshing highland air.

📍 How to Get There

Los Gemelos is located along the main road between Puerto Ayora and Baltra Airport, making it a convenient stop either upon arrival or before departure from Santa Cruz Island. The site is about a 30-minute drive from Puerto Ayora, and most highlands tours include this stop. You can also visit independently by taxi or rental vehicle.

🗺️ What to Do at Los Gemelos

• Explore the Observation Trails: Walk along easy, well-maintained paths that lead to scenic viewpoints overlooking both craters.
• Birdwatching: Bring your binoculars to spot endemic bird species that thrive in the highland ecosystem.
• Photography: Capture stunning photos of the crater walls blanketed in lush greenery and shrouded in mist—especially dramatic in the early morning.
• Learn About Galápagos Geology: Understand how these unique formations were created through volcanic activity and natural erosion.

📅 Best Time to Visit

Los Gemelos can be visited year-round, but the cooler dry season from June to December offers clearer skies and better hiking conditions. The warmer wet season from January to May brings lush, green landscapes and is excellent for birdwatching, though occasional rain showers are common.

💡 Travel Tips

• Dress in Layers: The highlands are cooler and more humid than the coastal areas—bring a light jacket or rain gear.
• Wear Comfortable Shoes: The trails are relatively easy, but sturdy shoes will keep you comfortable on uneven terrain.
• Combine Your Visit: Many travelers pair Los Gemelos with stops at El Chato Tortoise Reserve or the lava tunnels for a full highlands experience.
• Visit Early or Late: Morning and late afternoon visits offer the best light for photography and fewer crowds.
