The Invermoriston Falls are a major draw for the area, with stunning views to be had all round. There is a fairly short walk on even terrain from the car park through a woodland area (with slightly less even terrain) which leads you out to a good vantage point. Worth taking a stroller for small legs. From here you can see other trails as well as a beautiful stone bridge for crossing and pooh sticks.
The best day to visit is a Tuesday as they open the dams upstream at Dundreggan and the waters get quite dramatic!
