The Trossachs is ideal for exploring on foot or on a mountain bike. This is partly because the terrain is slightly more benign than the Highlands proper, but much is due to the excellent management of the Queen Elizabeth Forest Park, a huge chunk of the national park between Loch Lomond and Loch Lubnaig. The main visitor centre for the area, David Marshall Lodge, is just outside Aberfoyle.
For hill-walkers, the prize peak is Ben Lomond (3192ft), best accessed from Rowardennan on Loch Lomond’s east shore. Other highlights include Ben Venue (2370ft) and Ben A’an (1520ft) on the shores of Loch Katrine, as well as Ben Ledi (2857ft), just northwest of Callander, which all offer relatively straightforward but very rewarding climbs and, on clear days, stunning views. Walkers can also choose from any number of waymarked routes through the forests and along lochsides; pick up a map of these at the visitor centre.
The area is also a popular spot for mountain biking, with a number of useful rental shops, a network of forest paths and one of the more impressive stretches of the National Cycle Network cutting through the region from Loch Lomond to Killin.
