The waterfall of the little fawn is hidden in the forest but easily reached on the cycle route. Expect to see the fall flowing all year round.

Carleatheran is a summit in the Gargunnock Hills standing at 485m and overlooking the Forth Valley. On the summit is an ancient cairn and a more recent trig point. It's the eastern point of an interesting ridge that stretches from Stronend in the west to this point. To the north of this ridge is a steep slope down to the Forth Valley but to the south the moorland is a much gentler slope. This feature creates the stunning views to the north and the bleak moorland to the south. Carleatheran is normally climbed from the north. It's a nice wild walk.

This walled island of trees is an earthen mound or barrow, which when excavated in 1758 was found to be full of clay urns - but what was it for?

This circular walk/cycle from Aberfoyle climbs mystical Doon Hill, reputed home of the faerie folk. It passes through beautiful native woodland, open countryside and riverside. At the top of the hill is the Fairy tree. (see photos). It is possible to cycle the track round the hill though gets a bit tricky for the inexperienced on the far side. On a mountain bike you can climb to the summit and a decent descent is to be had from there. Alternatively leave your bike at the foot of the marked trail to the top of the hill. It will be watched over by the fairies.
