A stone cairn marks the summit. Don't get confused by the slightly lower cairn, just as you come onto the plateau. The true summit cairn is slightly further along and off the path to the left - easy to miss.
This steep little hill climbs from 44m at the crossroads up to 127m. This takes about 800m with the steepest bit while riding the edge of the woodland, it levels out a bit as you get to the top.
