You book a session, and once it is confirmed they send you a meeting time and place, chosen on the day for the weather and for what you want out of it. Gorge walking usually gathers at the Sligachan hotel. Coasteering is usually somewhere north of Staffin.
For the water they hand you a five millimetre wetsuit, rash vest, buoyancy aid, helmet, gloves and socks, so all you bring is yourself and a towel. Some swimming and moderate fitness will do it; the jumps are optional and you can have the whole session without doing one. For the hill you bring boots and waterproofs, though they will lend boots, helmets and harnesses for the Cuillin.
John and Sarah live on the island. Between sessions they run a race with no prize, a course for islanders new to the hills, and a tool library for repairing Cuillin paths.
