Snorkeling Los Túneles in the Galapagos Islands: A Travel Guide

The Galapagos Islands, located 600 miles off the coast of Ecuador, are one of the most biodiverse regions on the planet. Known for its rare species and unique landscapes, the archipelago attracts adventurers and nature enthusiasts from around the world.

One of the most fascinating sites in the Galapagos is Los Túneles, a natural underwater labyrinth off the coast of Isabela Island. Famous for its crystal-clear waters, stunning volcanic formations, and rich marine life, Los Túneles offers one of the most unique snorkeling experiences anywhere.

This guide will walk you through everything you need to know about snorkeling at Los Túneles, from the best time to visit, how to get there, what to expect in terms of wildlife, and essential tips for an unforgettable adventure.

What is Los Túneles?

Los Túneles, also known as “The Tunnels,” is a breathtaking snorkel site formed by lava flow tunnels and arches that create a complex series of underwater passageways.

These formations were created when molten lava met the cold seawater and solidified, forming intricate tunnels both above and below the surface. The result is a unique labyrinth of arches, channels, and pools that provide habitat for a wide range of marine species.

Due to its sheltered, shallow waters and clear visibility, Los Túneles is considered one of the best places to snorkel in the Galapagos Islands. It is renowned for its abundance of wildlife, including sea turtles, rays, sharks, and an array of colorful fish.

The area also offers striking views of the volcanic landscape above the water, making it a favorite spot for both snorkelers and photographers alike.

How to Get to Los Túneles

Getting to Isabela Island

The journey to Los Túneles starts on Isabela Island, the largest island in the Galapagos. Visitors usually fly into Baltra Island, which hosts the main airport for the Galapagos. From Baltra, you can take a ferry or a short plane ride to Isabela Island. Once on Isabela, you’ll need to book a guided snorkeling tour to reach Los Túneles, as independent trips are not permitted due to conservation regulations.

Best Time to Snorkel in Los Túneles

Weather Considerations

The Galapagos Islands have a tropical climate, but conditions can vary throughout the year. The best time to snorkel in Los Túneles is generally during the warm season from December to May. During this period, water temperatures are warmer (around 73°F to 77°F or 23°C to 25°C), and the sea is calmer, offering excellent visibility for snorkeling.

The cooler season runs from June to November and is characterized by cooler water temperatures (around 66°F to 72°F or 19°C to 22°C), stronger winds, and more choppy waters. However, this season is also a great time for wildlife encounters, especially if you’re interested in seeing larger marine species such as sharks and rays.

Wildlife Considerations

Marine life is abundant year-round in Los Túneles, but certain species are more active at specific times of the year. For instance, the Galapagos penguins, one of the few penguin species that live in a tropical environment, are more likely to be spotted during the cooler months. Manta rays and whale sharks are often seen between June and October, making it a great time for snorkelers looking for larger pelagic creatures.

What to Expect During Your Snorkeling Tour

Wildlife Encounters

Snorkeling at Los Túneles offers an incredible opportunity to get up close and personal with a wide variety of marine animals. Some of the most common species you’ll encounter include:

• Galapagos Green Sea Turtles: These majestic creatures are often found gliding through the calm waters of the tunnels.
• White-tipped Reef Sharks: While these sharks may look intimidating, they are harmless to humans and can often be seen resting on the seafloor.
• Manta Rays and Eagle Rays: Known for their graceful swimming, these rays are often spotted cruising through the water.
• Galapagos Penguins: The only penguin species found north of the equator, these playful birds are a delight to see darting through the water.
• Seahorses: Keep your eyes peeled for these tiny, camouflaged creatures hiding in the seagrass.
• Colorful Fish: From parrotfish to surgeonfish, the diversity of brightly colored fish is astounding.

Underwater Landscape

The volcanic tunnels and formations at Los Túneles create a stunning underwater landscape that is unlike anywhere else in the world. Snorkelers can weave through natural arches, swim over lava bridges, and explore the crevices and channels that make this site so unique. The waters are shallow, often only 5 to 10 meters deep, allowing for easy exploration and great visibility.

Above water, you’ll be treated to views of the volcanic coastline, where the jagged black rocks contrast with the deep blue ocean. The natural beauty of the surrounding area is just as captivating as the underwater sights.

Essential Gear for Snorkeling in Los Túneles

Most tour operators provide basic snorkeling gear such as a mask, snorkel, and fins, but it’s important to check what’s included when you book. If you prefer to bring your own gear, here are some essentials:

• Mask and Snorkel: A high-quality mask with a comfortable fit will ensure you can fully enjoy the underwater views. Consider bringing a snorkel with a purge valve to help clear water easily.
• Fins: Fins will help you navigate through the water more efficiently, especially in the slightly stronger currents found in some areas of the tunnels.
• Wetsuit: While the water is warmer during the December to May season, a 3mm wetsuit can provide extra comfort and buoyancy. During the cooler season, a thicker wetsuit (5mm) is recommended.
• Underwater Camera: Los Túneles is a photographer’s paradise, both above and below water. Bringing a waterproof camera or a GoPro will allow you to capture the incredible marine life and volcanic scenery.
• Reef-Safe Sunscreen: The sun can be strong in the Galapagos, but it’s important to use a reef-safe sunscreen to protect the marine ecosystem.
