Snowmobiling on the second-largest frozen glacier in Iceland is not an adventure you'd want to miss. Participants can choose a pick-up service from Reykjavik or directly head to Gullfoss to join the rest of the group on-site. The ride is guided, lasts about four to five hours, it is totally safe and available for everyone who is over eight years of age. Keep in mind that snowmobiling gear is not provided, so you'll need to take care of it prior to the ride.
