There are plenty of lovely local walks around Alyth and the surrounding area, from a stroll around the Den of Alyth to exploring Glen Isla with its dramatic waterfall at Reekie Linn. The other Angus Glens made up of Glen Clova, Glen Doll and Glen Esk are a short journey away and are a fabulous location for walks of all grades from a gente ramble to a challenging hike. The Walk Highlands site has some great information on walks in the area, including downloadable guides and is well worth taking a look at as you plan your walks.
The Cateran Trail is a 65 mile circular route which starts and ends in Blairgowrie, and passes through Alyth. Based on ancient drovers paths it takes you through some of the loveliest countryside in the area. It is a great blend of riverside and woodland, open moorland and glimpses of the Highlands. You don’t have to walk it all on one go of course: it can be split into 5 or 6 walks ranging from 4 to 7 hours in length. Details of the Cateran Trail walks can be found on the Walk Highlands site.
