From Redhill bus station, bus 410 at 11.05 to Bletchingley. Walk to Inn on the Pond at Nutfield Marsh for lunch or picnic. After lunch, walk alongside the lake in Mercers Country Park and then through The Moors nature reserve to Redhill. Train back to East Croydon . There is the opportunity to leave the walk early (after about 3.3 miles) by catching a bus soon after lunch to Redhill.
For those returning by rail, you should be back to East Croydon by 15.45. It is possible to return using the 420 bus but I can't guarantee finishing the walk in time to catch the 15.17 to Sutton.
Text by 1pm on Monday 13th to book for pub lunch.
