Iceland's Golden Circle is one of the great road trips of the world: ancient history, erupting geysers, and thundering waterfalls in a single extraordinary day. This tour adds something that belongs on a completely different list - snorkeling through Silfra Fissure, widely regarded as one of the clearest dive sites on the planet, with underwater visibility that regularly exceeds 100 metres.

This is a fully private tour. Your group - up to 3 people in a private sedan, or up to 8 in a private minivan - gets a dedicated guide and a vehicle that belongs entirely to you for the day. No fixed pace, no waiting for other passengers, no compromises. If you want to stay longer at Gullfoss because the light is perfect, you stay. If you want to watch Strokkur erupt one more time, you watch. The day is yours.

Your private guide brings deep knowledge of Iceland's history, culture, and landscape to every stop. They are there to answer questions, provide context, and make sure your group gets the most out of every moment on the route.

The snorkeling itself takes place at Þingvellir National Park, where the Silfra Fissure cuts through the earth between two continents. A certified local snorkeling guide leads your group through the fissure in a dry suit - no experience required. The water temperature stays at a constant 2-4°C year-round, but the dry suit keeps you warm and the visibility is unlike anything most people have ever seen underwater. Floating through Silfra is genuinely one of Iceland's most remarkable experiences.

Full details of each stop are in the itinerary. Door-to-door pickup and drop-off from your Reykjavík accommodation is included. The itinerary order may be adjusted on the day due to weather or road conditions.

Please note: the entrance fee for Silfra Snorkeling is not included in the initial price but can be added at the checkout page.
