From the Inversnaid Hotel, walk down to the harbour and around towards the waterfall. There are a few boulders to scramble over to get to the water (or you can walk further along for beach accesses). Stunning views down the loch and across to the hills. Added bonus of post-swim jacuzzi in the waterfall pool!

Watch out for ferries using the harbour and other boats on the loch
