You do not need to be an experienced diver to experience Silfra. Every year, thousands of first-timers slip beneath the surface of this glacial fissure and come up transformed. If you are planning your first visit, here is everything you need to know before you arrive.
First, decide on your experience type. Snorkelling requires no prior experience and is the most accessible way to see Silfra. Freediving tours are suitable for anyone comfortable in water and able to hold their breath for a few seconds — your guide will coach you through basic technique. Scuba diving requires an Open Water certification or higher and also a drysuit certification.
Arrive at Þingvellir National Park with time to spare. Your guide will meet you at the Silfra car park (you can park at P5 car park) and brief the group before you suit up. The changing process takes around 20–30 minutes. Wetsuits are fitted on-site and your guide will check everything is secure before you enter the water.
The water entry is a short walk from the changing area. The cold on your face is the first thing you will notice — it is sharp and clarifying, like nothing else. Within a minute, you will forget about the temperature entirely and start absorbing the views. The water is so clear it looks almost unreal, more like flying than swimming.
The tour typically lasts around two and a half hours including briefing, suiting up, the dive itself, and changing back. Warm drinks after the dive are very welcome. Dress normally and remember to take a towel and swimsuit with you for the wetsuit. Silfra is unforgettable. The only mistake is not booking it.
