These woods near Arundel have good mountain bike trails and some nice footpaths to try. You can park at the Whiteways Countryside car park, just off the A29 at the south eastern end of the forest. From here you can pick up the trails heading north west through the woods. You could also follow either the Monarch's Way or South Downs Way from the village of Houghton. You can also extend your walking in the area by continuing along either of these long distance trails or the Midhurst Way which also passes through the forest.
