Ninety per cent of your time is spent in shorts and T-shirt both under and over the water. Bring one set of warm clothes for the cold weather on arrival and departure. The best time to go is mid-spring or mid-autumn. Temperatures are in the high 70s\low 80s and the heat is pleasant rather than oppressive. Bring a good head torch – it proved very useful when returning to the tent at night. Try to have a reasonable standard of fitness. To be able to walk for one hour on the flat at a reasonable pace should suffice.
