More ways to explore the area's outdoor wonders
You surface into a sky so clean it feels like a punch of cold light, and below, the water is the color of polished glass. On the shore of Þingvellir, the rift between the Eurasian and North American plates narrows into Silfra, a fissure carved by glacial melt and tectonic insistence. When you step into the dry suit and slip your fins on under a pale Icelandic sun, the fissure doesn’t feel like a geological map— it feels like a corridor that pulls you between two worlds.

Bring your dry-suit certification
Operators require proof of dry-suit certification or a logbook with at least 10 dry-suit dives; your guide will check credentials before boarding.
Dress for the walk back
After the dive there’s a short 300 m (984 ft) walk to the car park—bring warm socks and a change of clothes to avoid hypothermia.
Skip glasses—use contacts or a prescription mask
Standard glasses won’t seal under a dive mask; bring contact lenses or a prescription dive mask to see clearly underwater.
Avoid flying immediately after diving
Plan flights at least 24 hours after diving to reduce the risk of decompression illness as standard diving protocol advises.
Thermal undergarments (wool or fleece)
Insulating layers worn under your dry suit retain warmth during long cold dives.
Warm socks and spare clothes
Change into dry clothing immediately after the dive to prevent chill on the walk back and transfer.
Contact lenses or prescription dive mask
Clear vision is essential; regular glasses cannot be worn under a dive mask.
Waterproof dry bag
Keeps your post-dive clothing and electronics dry during transfers and the short walk to the exit.
