Davíðsgjá Dive Tour

A Hidden Fissure Dive in Þingvellir's Great Lake

3 hoursLanguages: English

The Davíðsgjá Dive Tour drops you into one of Iceland's lesser-known underwater fissures: a deep, narrow rift beneath Lake Þingvallavatn that local divers quietly rate among the country's finest.

A short drive from Silfra inside Þingvellir National Park, Davíðsgjá rewards dry-suit divers with glassy water, towering basalt walls and resident brown trout, all on a relaxed, self-drive half-day.

A hidden fissure beneath Lake Þingvallavatn

Davíðsgjá, or “David's fissure,” lies below the surface of Lake Þingvallavatn in Þingvellir National Park. Unlike its world-famous neighbour Silfra, it draws few international divers, so a dive here still feels like a local secret.

What the dive is like

You enter straight from the shore, and after a short, shallow swim you drop into the long, narrow rift, which reaches a maximum depth of 21 metres. The top of the fissure sits around 7 metres down and opens to the lake, so curious brown trout often join you along the way.

Davíðsgjá tends to run a touch warmer than Silfra and can serve up superb visibility, though conditions here lean more on the weather. Divers fondly call it Silfra's wilder, darker sibling.

Who can dive here

This is a dry-suit dive for certified divers. You'll need a dry-suit certification, or at least ten logged dry-suit dives in the past two years with written confirmation from an instructor. Not qualified yet? You can add a dry-suit course, or choose to snorkel Silfra instead.

Pair it with the Golden Circle

Davíðsgjá sits right on the Golden Circle, so it slots neatly alongside Gullfoss waterfall, the Geysir geothermal area and Kerið crater. Keen divers can also tackle Silfra and Davíðsgjá together in a single day.

Diving Silfra Tour with Pick Up

The Diving Silfra Day Tour takes you into one of the most remarkable dive sites on the planet. Silfra is a natural fissure created by the slow separation of the North American and Eurasian tectonic plates. Here, you descend into glacial meltwater renowned for its extreme clarity, offering visibility that can exceed 100 meters. The water you dive in has travelled for decades through porous volcanic lava, acting as a natural filtration system and creating an underwater environment unlike anything else on Earth. The result is a surreal, light-filled landscape found nowhere else in the world.
