You’ll head out to one of the most remarkable areas of Isabela Island to explore calm channels shaped by ancient lava flows. Clear water, gentle movement, and high wildlife activity make this an ideal place for a relaxed yet memorable snorkelling day. You’ll be supported throughout while learning about the area’s unique marine life and geology.
Your day starts with a short briefing before boarding the boat for the journey along Isabela’s coast. The ride gives you time to settle in as your guide shares stories about the volcanic history and what you’re likely to see. On arrival, the arches and channels become clear, offering sheltered water with excellent visibility. You’ll enter the water at an easy pace, allowing plenty of time to adjust to the equipment before moving through the tunnels.
Once inside the channels, marine life becomes the focus. Sea turtles often glide slowly past, rays move along the sand, and reef sharks rest in the shaded areas beneath the arches. Seahorses, marine iguanas, and colourful fish appear frequently, giving you a good mix of species to observe. After the snorkelling sessions, you’ll explore parts of the arches on foot, where coastal birds nest and feed. Your guide will explain the role these formations play in supporting such a wide range of life, giving you a clear picture of the area’s ecological importance.
Isabela Island is known for its dramatic volcanic landscape, shaped by six volcanoes that form the largest landmass in the archipelago. Travelling to Los Tuneles takes you through an area famous for its clear water and striking contrast between black lava rock and bright blue sea. The shallow channels carved by past eruptions create a safe place for marine life to gather, and the conditions make it easy to see into the water from both the boat and the surface.
Neighbouring bays and coastal stretches often provide extra wildlife sightings before and after the main snorkelling area. Sea turtles frequently feed close to shore, while rays slip across the sand in deeper pockets. Frigatebirds, boobies, and other seabirds make good use of the updrafts, adding activity above the waterline. Together, these elements make the wider area around Los Tuneles one of the most rewarding regions to explore on Isabela.
Basic swimming ability is recommended so you can comfortably use the snorkelling equipment and enjoy moving through the channels at a relaxed pace. Guidance is given before entering the water, and the session is structured to support those who might need a little extra time getting used to breathing through a snorkel.
General good health helps you make the most of the day because the activity involves swimming, climbing in and out of the boat, and walking across uneven volcanic rock. If you have concerns about mobility, confidence in open water, or comfort with equipment, you can mention these beforehand so the guide can adapt the day when possible.
Local knowledge shapes every part of the experience, with guidance coming from someone who grew up in the islands and has spent years studying and protecting their wildlife. Explanations are clear and engaging, helping you understand not just what you’re seeing but why these environments matter. This depth of insight often makes the day feel personal and meaningful.
Low-impact practices are part of every tour, with support for coastal cleanup efforts and partnerships that directly benefit the community. Responsible routes, small groups, and careful wildlife viewing ensure your visit contributes positively to the islands. Guests frequently comment on how this approach adds value and offers a deeper connection to the landscapes and species they encounter.
