Length: Up to 12 km (7.5 miles). Toughness: 1/10
10:41 Clacton-on-Sea train from Liverpool Street (Stratford 10:48), changing at Thorpe-le-Soken (arr 12:03, dep 12:06) for the shuttle service to Walton-on-the-Naze, arriving there at 12:18.
Trains back from Walton-on-the-Naze are hourly at xx:30 to 21:30, again changing at Thorpe-le-Soken. There's one final train at 22:25 requiring an extra change at Colchester, but you might need a night bus to get home after returning at midnight.
With a heatwave forecast for next weekend my original plan for a hilly walk in the High Weald didn't look too appealing, so I've substituted this rarely-posted beach walk where you should be able to cool off with a quick dip in the sea. As high tide is at 15:21 it seems sensible to walk out along the beach and return via the low cliffs (or along the sea wall behind a nature reserve), as suggested in the fairly sparse directions. Please read the walk notes carefully and follow any local signs as some optional parts of the route might be inaccessible.
Refreshments are available en route at The Naze Tower and of course there'll be a good choice back in Walton itself. You probably won't want a longer walk but the author recommends a stroll out along the pier (or carrying on along the seafront to Frinton) as possible extensions for anyone who hasn't wilted in the heat.
Please bring the walk notes from the L=swc.98 with you.
