Tracks as far as Beinn Dearg, good luck beyond!
Seriously though, the ground is heather/grass/bog, there are no cliffs, makes everything really simple.
Looong track from the ruined lodge out to Linn of Dee, on a bike it felt long, but hell the quality of remoteness on those two Munros is stunning.
Bring gaiters, the heather clawing at the ankles gets annoying here more than anywhere else imo.
It can be easier to go over the tops of the gentle summit domes in this place, than thru the rivers between with thick heather - never experienced this anywhere else which is why I mention.
The isolation in the Tarf basin is fantastic - one of the genuinely humbling places of the Highlands in my experience.
