Description

Join this once-in-a-lifetime snorkeling tour in Silfra, where you’ll float between two continents in some of the clearest water on Earth!

Tucked inside Thingvellir National Park, this stunning fissure marks the separation of the North American and Eurasian tectonic plates. With visibility often reaching 100 meters, the view under the surface is truly mesmerizing.

Meet your guide at the Silfra car park 15 minutes before the tour starts. You can choose to be picked up in Reykjavik or make your own way to the meeting point.

Your expert PADI guide will lead you through all four main sections of Silfra, from narrow passageways to wide, light-filled chambers. The slow current lets you relax and take in every detail. The tour is suitable for anyone who can swim—no prior snorkeling experience needed.

You’ll be fitted with a drysuit, hood, gloves, and fins to keep you dry and insulated in the 36–39°F (2–4°C) water. Your guide will provide a comprehensive briefing covering the area’s history, safety guidelines, and how to properly use your equipment.

After a short walk, you’ll enter Silfra’s glacier-clear waters and begin your swim between the tectonic plates. Drift through vivid blue channels with up to 150 meters (490 feet) visibility, guided by a gentle current. While it may feel chilly at first, the surreal beauty around you quickly takes over. Snorkeling in Silfra is peaceful, otherworldly, and unlike anything else in Iceland.

You'll snorkel for approximately 30–40 minutes before exiting at Silfra Lagoon. Afterward, it's a 400-meter (1,300-foot) walk back to the parking lot.

After your snorkeling tour, warm up with hot chocolate and cookies, and get access to your free underwater photos.

Bring thermal base layers, warm socks, and weather-appropriate outdoor clothing. The minimum age for this snorkeling tour in Silfra is 12, and you must be able to swim. 

Silfra lies within Thingvellir National Park, a UNESCO World Heritage Site rich in both natural beauty and Icelandic history. It's also part of the Golden Circle, making this the perfect activity before seeing the rest of the route.

Good to know

To fully enjoy your Silfra snorkeling experience, participants need to be comfortable in the water and able to swim confidently. The tour is conducted entirely in English, so it’s important that guests can understand and communicate in English to follow safety instructions and guidance.

This tour is not suitable for pregnant individuals due to the small risk of cold water entering the dry suit. For everyone else, dressing warmly in layers is key—wear a thermal base layer and warm socks under the dry suit. All snorkeling gear, including dry suits, masks, and fins, will be provided.

You’ll spend around 30–40 minutes in the glacier-clear water, so comfort and readiness are essential. While food is not included, hot cocoa and cookies will be served after the tour to warm you up and make the experience even more enjoyable. You’re also welcome to bring snacks and water if you like.

Please note that snorkeling masks cannot be worn with glasses, so bring contact lenses if needed. For safety and comfort, participants must fit within the dry suit size range: 99–265 lbs (45–120 kg) and 4'11"–6'7" (150–200 cm). If you have any medical concerns, consult your doctor before booking.
