Hi Lincolnshirelad, add to those already mentioned, Southern Cairngorms from Braemar, Ben Lawers range, Schiehallion, Drumochter there are absolutely loads, it really depends on your fitness and speed of walking, and are you looking for a specific type of hillwalk ie including a few munros, or single, must they be munros, casual or rocky scramble, high summit traverse? also give us pointer re maximum distance
