Since Scotland is full of small lakes that promise nice views due to their proximity to mountains, I am wondering if I can rent a boat/kayak/canoe on some of them? I'd be particularly interested in a place that is accessible by car (or by 0.5-1h hike from a parking), where I can go on water for a few hours and ideally reach the other side of the lake, where I could have a picnic/see some old ruins/relax on a remote beach or simply enjoy a beautiful view — basically something that would make crossing the lake worthwhile. Oh, I'm not really interested in motorboats, I'd rather paddle by myself.
I am especially interested in lochs in the West: around Loch Lomond, Oban, Mull, Fort William and Skye. Is this at all possible? Could you recommend a good loch for this?
