South Downs
This is a great walk for those living in London as its just over 1 hour away from Victoria station.
Take the train to Arundel, then walk to the Arundel community hospital. There will be a bridal path just before reaching the hospital. Take the bridal path and follow it along until you reach a gate leading to a farm. Once here, you can strip off safely.
Follow the bridal path through the farm until you reach Rewell Woods, where you can walk around and tailor your walk length. This woods is very quiet, with mainly forest workers about.
Once youve finished in Rewell Woods, head north east to Houghton Forest. You will have to cross a road and will need to cover up for it. Follow the path before crossing another small road. After crossing the road, you can strip off again and walk around Houghton Woods. There are some steeper inclines here, so be warned.
From Houghton Forest, you can either go east bound further in the South Downs, or follow your path back to go home.
