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. 🧭 Key Details Duration: 6 hours Location: Los Tuneles, Isabela Island Group size: 1–6 people Age: 10+ 🌊 What to Expect 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. 📍 Location 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. 📝 Prerequisites Basic swimming ability is recommended so you can comfortably use the sno… ### Essential information _None._ ### What’s included Snorkelling equipment Wetsuit Boat transport during the activity Certified naturalist guide Snacks and drinks on board ### What’s not included Lunch Personal insurance Transport to and from the meeting point ### Kit list _None._ ## FAQs _No FAQs in catalog._ ## Media - **Primary image URL (resolved in app; may be absolute)**: https://adventuro.com/wp-content/uploads/2025/12/Screenshot-2025-12-02-074620.png - **Gallery image count**: 3 ## Limitations - Availability, exact session times, and final price may depend on the live booking flow. - This Markdown is generated from the same catalog fields as the public HTML page at the canonical URL above.
