More ways to explore the area's outdoor wonders
A pale-blue slit in the volcanic rock draws you down a narrow path at Þingvellir. The air is sharp; the rift breathes a cold, mineral scent that promises clarity. At Silfra you stand on the edge of two continents—North American and Eurasian plates—then slip into glacial water filtered for decades through lava fields. The water is a startling, drinkable clarity at about 2–4°C; suits and guided care keep you safe while the fissure’s walls and submerged plates become a slow-motion landscape beneath your mask.

Dress warm under your drysuit
Wear thermal long underwear and thick wool socks under the provided drysuit to retain heat during the snorkel.
Provide measurements early
Submit height, weight and age at booking—suit fit is critical and operators need this before you arrive.
Eat beforehand
The full itinerary is long and cold-water exposure burns energy—have a solid breakfast before the trip.
Bring a change of clothes
While drysuits are reliable, they can leak; bring warm dry clothes and a waterproof bag for the wet suit.
Thermal base layers
Retain body heat under the drysuit during the cold-water snorkel.
Thick wool socks
Provide insulation in boots and help regulate warmth when changing after the dive.
Prescription snorkel mask or contact lenses
Avoid glasses under the mask—bring contacts or your own corrective mask if needed.
Waterproof change of clothes and towel
Necessary after the snorkel since suits can feel tight or occasionally leak.
