The River Earn flows east from the loch and meets the River Tay at Bridge of Earn. The most popular destination on the loch is the Lochearnhead Water Sports Centre, which offers a variety of water sports activities including sailing, canoeing, and windsurfing. The loch is swell-stocked with fish including rainbow trout and brown trout, and fishing is available with the use of a permit.
If you fancy a bit of exercise on dry land, head for the peak of Ben Vorlich, on the south side of the loch. Ben Vorlich reaches a height of 985 metres and is extremely popular with walkers, drawn by the exceptional views to be had from the summit, with a panoramic vista stretching over the national park.
The best historic attraction is Edinample Castle near Lochearnhead. The castle was built in 1584 by 'Black' Duncan Campbell of Glenorchy. Campbell was a hard man to please, and rumour has it that he pushed his builder off the castle roof because he had failed to build ramparts to Campbell's desire - and so the laird could avoid paying his fee. The builder's ghost is said to walk the roof. The castle is now a private dwelling and is not open to the public.
East of the castle is Ardvorlich House, built in 1580 by the Stewart family and rebuilt in 1790.
