My own suggested walking route is perhaps rather more speculative.
The south Devon Kingsbridge branch line never reached the coast as far as Salcombe, but if it had, there would have been opportunities for some fantastic coastal walks, towards Dartmouth.
Even from Kingsbridge on the estuary, walking due east to Slapton Sands, there are still some stunning views of Devon countryside to be enjoyed.
I very much concur. Over the years I've covered pretty much all of the coast path between Salcombe and Dartmouth and in the opposite direction between Salcombe and Bigbury on Sea/Burgh Island.
The Kingsbridge/Salcombe estuary doesn't have SW Coast Path all around it but there are long stretches of coastal road and footpaths along many of the creeks. There's refreshment opportunities too...the Ferry Inn in Salcombe is conveniently next to the ferry steps and in the lovely village of Southpool you can find the Millbrook Inn at the head of the creek. Kingsbridge too offers the waterside delights of the Crabshell Inn.
Other pubs are also available!
