Nearest Station: Eltham or Falconwood
Another gem in the Eltham area, Oxleas Wood is an ancient deciduous forest, some parts of which date back 8,000 years. Walking through these atmospheric woods, you'll quickly forget you're still within the M25! Nestled within is Severndroog Castle, a folly with hexagonal turrets built in the late 1700s. It was recently reopened to the public following restorations, and it's definitely worth a visit.
