Buy a return to Redhill and leave station on the east side, by the A25 hill. Along a suburban road to quickly reach the woods and Moors Nature Reserve with its lakes. Through Mercers Marina, then across Nutfield Marsh for lunch at The Inn on the Pond (picnic possible). Up the hill behind to cross (muddy!) fields and up again to The White Hart Bus Stop for the 410 back to Redhill Bus Station. Possible free (with bus pass) return trip using the 420 (allow 75 minutes to/from Sutton). Text me to book by Monday 6pm.
