We suggest wearing clothes that you don’t mind getting a bit wet. Swimwear is essential if you wish to swim, a quick dry t-shirt, hat, sunglasses, shorts. Sandals, open shoes and socks are not recommended as they tend to get soggy. Hiking shoes or trainersare fine. A lightweight polypropylene or fleece layer should be included in early spring and late fall tours. Wetsuits are provided as well as dry bags where you can store your phone or some other personal belongings.
