A small summit above Risca. Known locally as the "Twmp" (the hump), the pimple or the nipple, due to the shape of the mound on the summit.

Can get pretty busy during the day in the summer, however there's a good selection of snacks, food and drink available.

Great single track. If you want the track to yourself, mid week and early is best. On a ebike it takes between 1.0 and 1.5 hours to get around it. I guess between 1.5 and 3.0 hours on a mountain bike without a motor, giving you plenty of time to tackle the CAFALL trail which is about the same length and starts from the same place. It is a red trail, but not particularly technical.
