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 ### How difficult is the snorkelling and how long will we be in the water? Most people find the sessions very manageable because the channels are sheltered and the current is gentle. Before entering the water, you’ll be shown how to use the mask and snorkel comfortably, and there’s no pressure to move quickly or keep up with anyone. The guide stays close enough to help whenever needed, making it easy to relax and enjoy the surroundings. Across the day, you’ll take part in two or three separate snorkelling sessions, usually lasting 30–45 minutes each. Breaks on the boat allow you to warm up, rest, have a drink, and ask questions about what you’ve seen. This structure keeps the day comfortable and avoids fatigue. ### What marine life is commonly seen during the experience? Sea turtles are often the stars of the day, feeding calmly in the channels and moving slowly enough that you can watch them at close range. White-tipped reef sharks rest under the arches, rays glide along the bottom, and seahorses can sometimes be spotted clinging to vegetation. Marine iguanas swim through the tunnels, and schools of tropical fish move in and out of the rock formations. Sightings vary slightly with conditions, but Los Tuneles is known for extremely reliable wildlife activity year-round. If one archway is quiet, your guide may move to another, where visibility and movement are better. Each stop offers a different perspective on how species use the lava formations. ### What is the boat ride like for those prone to seasickness? The journey to Los Tuneles is usually smooth, but open water can occasionally produce light movement. If you are sensitive to motion, taking a suitable remedy ahead of time helps a great deal. Sitting near the back of the boat, breathing steadily, and keeping your eyes on the horizon also reduces discomfort. Your guide monitors conditions throughout the day and adjusts speed or direction if anyone begins to feel unwell. Short pauses can be made when necessary, and the relaxed pace ensures you’re supported rather than rushed. ### What should I bring with me on the day? You’ll only need essentials such as a towel, sun protection, and a light layer for after the snorkelling sessions. Swimwear should be worn under your clothing so you’re ready to begin once you reach the site. A reusable water bottle is recommended as part of the low-waste approach taken throughout the activity. If you plan to bring electronics, keep them in a waterproof pouch to avoid accidental splashes. The guide will let you know when conditions are best for taking photos and when it’s better to keep devices stored safely. ### Will I need a wetsuit and how warm is the water? Season, currents, and depth all influence water temperature, and many guests appreciate the added warmth a wetsuit provides. Wetsuits are included and available in several sizes, and the guide will help you choose one that fits comfortably. Wearing one allows you to stay in the water longer without cooling down too quickly. Between snorkelling sessions, warm drinks and snacks help maintain your energy. Even during cooler months, the sheltered structure of the tunnels keeps conditions more comfortable than in open water. ### What happens if weather or ocean conditions change suddenly? Weather and sea conditions can shift quickly, and your guide will make safe, sensible adjustments if needed. Alternative sheltered areas may be used if the original site becomes unsuitable. These changes are made with the aim of keeping the day both safe and enjoyable. If rare circumstances prevent the tour from running as planned, you’ll be told as early as possible. Clear communication ensures expectations are managed while still offering the best possible experience based on conditions. ### Can I bring an underwater camera? Underwater cameras are welcome, and clear visibility often leads to excellent photos. Before entering the water, it’s important to check that all seals and connections on your housing are secure. The guide can point out subjects or angles at appropriate moments without disturbing the wildlife. Those without a camera still find plenty of opportunities for good pictures above the surface, especially around the arches and bird nesting sites. Being present in the moment often makes the sightings even more memorable, whether or not you’re taking photos. ### Do I need previous snorkelling experience? First-time snorkellers usually feel comfortable very quickly thanks to the calm conditions and supportive guidance. You’ll have time to practise at the surface before moving into the channels, and the pace remains relaxed throughout the day. Clear instructions make it easy to learn the basics without stress. Those with experience appreciate the mix of wildlife and geological features that are unique to Los Tuneles. Swimmers familiar with snorkelling often find the area particularly satisfying because each archway reveals something different. ## Media - **Primary image URL (resolved in app; may be absolute)**: https://adventuro.com/cdn-cgi/image/width=1200,format=auto,quality=90/https://wp.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.
