Bac Lava: A sublime sandy beach on the side of a promontory. Few lochs offer sandy beaches and shallow entry as this one does.
Holly Waters: Go for the Forestry Commission spot 'Jubilee Point' - ticks every box except jumping ( shallow entry, though soon gets deeper) and skinny dipping, though there is a sheltered bay along a path to the north, which is suitable.
-Rumour of currents, but not noticeable in mid-July.
Paul Marsh: This is a lovely place for a summer swim and or cayak... followed by a bbq... just remember take all your bits away and leave nothing but memories! :)
None... well OK one.. you may never want to leave!
