The wind that strips across Thingvellir carries a cold, clean smell—earth and glacier mingled—and it pushes you toward a seam in the world. Walk down the gravel path from the small car park, past low lava outcrops and a visitor sign, and the fissure opens: a ribbon of glass-clear water cutting between two tectonic plates. Underwater, the rift reads like a geological cross-section; above it, the Icelandic sky is vast and hard.

Adventure Tips
Bring your dry-suit certification
You must present dry-suit certification or a logbook showing at least 10 dry-suit dives within the last two years to participate.
Prepare for cold water
Wear warm thermal undergarments and heavy socks beneath the provided dry suit; water temperatures are typically 2–4°C in winter.
Plan logistics
Park at Thingvellir P5 and expect to walk about 400m to the diver parking area; arrive 15 minutes early for kit-up.
Avoid flying after diving
Wait at least 24 hours after your dive before flying to reduce decompression risk.

History
Thingvellir hosted the Althing from 930 AD, one of the world's oldest parliamentary assemblies; the fissure itself is visible evidence of tectonic forces that continue to shape Iceland.
Conservation
Silfra is tightly regulated to protect its pristine glacier water—group sizes, depth limits, and strict gear protocols minimize human impact.

Change of warm clothes and extra socks
