Step from Iceland’s cold air into a corridor of glass-clear glacial water and literally float between continents. This three-hour Silfra drysuit snorkeling experience at Thingvellir National Park combines geological wonder with practical safety and professional photos.
More ways to explore the area's outdoor wonders
A chill bites at your cheeks long before the water does. You hike from the P5 lot across pumice-gray road and lichen-scattered ground until the fissure broadens and the air smells of cold mineral water. Guides clip on waterproof cameras and check seals; the drysuits stand like small, bright buoys against the dark rocks. When you slip into Silfra, you don’t so much enter water as step into visibility: the fissure lets you see 30 metres—then 60—then farther, the world beneath the surface oversized and exact.

Arrive Early to Find P5 Parking
Park at Thingvellir P5 and walk the short route to the meeting point; arrive 15 minutes early to complete paperwork and kit-up calmly.
Dress in Layers for the Dry Suit
Wear long thermal underwear and thick wool socks under the drysuit; bring gloves and a hat for shore time before and after the swim.
Know Your Health Limits
You must be a confident swimmer and disclose medical info ahead of time—pregnancy, heart, or spinal conditions are contraindications.
Use the Guides’ Cameras
Underwater photos are included—let guides shoot to avoid fumbling devices in cold water, but bring a dry bag for a spare phone or small camera.
Thermal base layers (tops and bottoms)
Thin, warm layers under a drysuit keep core temperature steady without bulk.
Thick wool socks
Wool socks protect feet inside the drysuit and retain warmth even if damp.
Waterproof camera or action camera (optional)
Useful if you prefer personal photos, though guides include professional shots.
Warm, quick-dry change of clothes
Change into dry layers immediately after the swim to avoid chill on the drive back to Reykjavík.
