Situated about 100 metres to the west of Plat Tor can be found an impressive stack of isolated granite on the edge of the woodland. This feature is marked on old OS maps as an area of exposed rock, but it is not named and has never been given recognition until now.
The most prominent section comprises one large granite boulder perched atop bedrock (grid ref: SX 7443 7934), but to the south of the wall, just below the lane and above the stack is a huge flat outcrop at SX 7442 7931. The area is best viewed in late April and early-mid May to observe a spectacular array of vibrant bluebells, among the finest that Dartmoor has to offer.
Not visible from anywhere as hidden in the vegetation, Culliver Stack is a mere 50 metres or so below the road just inside the old enclosure wall. When consulting the Tithe Map for the Parish of Manaton, the plots here are collectively shown as 'Culliver'; the name of which seems appropriate for this tor.
