Reykjavík: Silfra Snorkeling & Golden Circle Small-Group Day Tour

This full-day small-group tour combines two of Iceland's most extraordinary experiences: snorkeling in the Silfra Fissure and a complete circuit of the Golden Circle. Hotel pickup in Reykjavík is included, and your certified PADI Divemaster guide accompanies you throughout the day.

The adventure begins at Þingvellir National Park, a UNESCO World Heritage Site where the North American and Eurasian tectonic plates meet. After a safety briefing, you are fitted with a full drysuit, thermal undersuit, neoprene hood and gloves, mask, snorkel, and fins. In the water, you drift through Silfra Hall — the fissure's widest chamber — and on to Silfra Cathedral, its deepest point, before reaching the shallow turquoise pool known as the Real Blue Lagoon.

The Golden Circle continues with a visit to the Geysir geothermal area, where the geyser Strokkur erupts up to 40 metres every five minutes, and hundreds of colourful hot springs dot the landscape. The tour then heads to Gullfoss, the thundering two-tiered waterfall fed by meltwater from Langjökull, Iceland's second-largest glacier.

Groups are kept small — a maximum of six participants per guide in the water — and free GoPro underwater photos are included so you can relive every moment of the dive.

Your guide collects you by minibus from a designated Reykjavík pickup point. The first stop is Þingvellir National Park, where you walk through volcanic, moss-covered terrain to the water's edge. Your PADI Divemaster delivers a thorough safety briefing before you are fitted with all snorkeling equipment.

In Silfra Fissure you drift through gin-clear glacial water, passing the canyon walls of Silfra Hall and descending to Silfra Cathedral before reaching the vivid shallow pool at the end. The drysuit keeps you buoyant and insulated throughout.

After drying off and warming up with hot drinks and chocolate bars, the tour continues to the Geysir geothermal area and the iconic Gullfoss waterfall. The tour runs for approximately 10 hours in total, with your guide providing commentary on Iceland's geology, history, and culture throughout.

This tour pairs the Golden Circle's three headline stops with a genuine snorkeling adventure in one of the world's clearest bodies of water — all in a single day and with hotel pickup included. The small-group format (maximum 6 per guide in the water) means personal attention from a certified PADI Divemaster. All snorkeling equipment, a warm drysuit and undersuit, free GoPro underwater photos, and hot drinks and chocolate bars after the snorkel are included in the price. No prior snorkeling experience is required.
