This is the summit of Brixham Hill, which is part of the Devon and Torbay 3 Peaks Hiking Challenge.
Brixham Hill is just inland of Southdown Cliff, with a lane than runs up the hill (Challeycroft Road). You don’t even need to hike this one!
For the purposes of this challenge, the summit covers all the upper part of Challeycroft Road.
However, nearby is Mansands Lane circular walk which may be worth combining with bagging this summit.
