Execellent mix of trails, although the sandy ones are hard work

It's a dead end for roadies as there's only one tarmacked road to it but it's a nice ride and there's the Tinto CafΓ© horsebox at the car park, which does hot drinks, sandwiches and toasties, cakes and snacks. Officially it closes at 4pm but it was still serving at 4.30 when I was there, thankfully.

There are plenty of trails here for walkers and cyclists, with picnic spots and sculptures to discover. Rendlesham Forest is famous for a supposed UFO sighting in December 1980. There's even a UFO trail, boasting a large model of an alien spacecraft.

Fun, flowy singletrack through the forest. The Viking Trail is a fantastic 10-mile (16km) red graded route.
