Part of the winter-friendly “Himbleton Highways” series; a circular walk along tarmac roads and lanes. For full details see “HH1 Nature Reserve”
You are looking for a camouflaged HIPS container. Tweezers may be needed.
NOTE: just down the hill from here towards HH21, there is a small teashop by the canal/marina, selling teas, snacks and giftware.
