Fairlop Waters Boulders in Barkingside is the perfect outdoorsy adventure for those who don¹t fancy a drive into the country. Indoor climbing centres are rare in London, but this one offers rock climbing sessions for beginners and advanced climbers alike – which means you won't feel self-conscious if you"re trying out the sport for the first time (phew). If that wasn¹t enough, you'll find a nine and 18-hole golf course nearby, as well as a driving range, nature trail, orienteering course and windsurfing and sailing lake. Plus, it's on the Central Line. Boom!
