Silfra Fissure Dry‑Suit Dive at Thingvellir — 4‑Hour Small‑Group Tour from Reykjavík
Dive between continents in one of the clearest bodies of water on Earth. This four‑hour dry‑suit dive at Silfra in Þingvellir is a small‑group, challenge‑rated experience that pairs geologic spectacle with strict safety and certification requirements.
The Experience
Before You Go
Bring warm underlayers
Wear wool or fleece base layers and warm socks beneath the provided thermal undersuit — the water is 2–4°C and a warm core matters before and after the dive.
Confirm your dry‑suit certification
You must present a dry‑suit certification or a logbook with at least 10 dry‑suit dives within the last two years — otherwise you cannot dive.
Plan your transport and timing
Park at Thingvellir P5 and expect a 400m walk to the meeting point; arrive 15 minutes early and be ready to carry equipment.
Avoid flights immediately after diving
Wait at least 24 hours after diving before flying to reduce the risk of decompression illness.

Conservation Note
Silfra is tightly regulated to protect its unique freshwater clarity — small group sizes, strict gear rules, and no‑contaminant policies help preserve the fissure.
Þingvellir was the site of Iceland’s Alþingi from 930 AD, where laws were made on these plains between tectonic plates.
