Bookings

This site sells nothing. You book on GetYourGuide, and your contract is with GetYourGuide and the operator. The price you pay is the one shown at checkout.

How we choose the tours

We start from the 21 snorkeling and diving tours listed for Silfra and the Golden Circle in our reading of GetYourGuide's Iceland pages, then keep the ones that truly include a swim at Silfra: 17. Nobody pays us to include a tour or to rank it higher.

How we check

Prices and ratings are read from GetYourGuide, and the day of the last check is shown under “Compare in detail”. They change with the date, and the price you pay is the one GetYourGuide shows you. When a tour disappears, we take it off the site. Every fact is listed with its source and the day we read it on Sources and method.

How the site earns money

We earn a commission if you book through our links, at no extra cost to you. Ratings are GetYourGuide's, shown with their number of reviews. We do not publish reviews of our own.
