I’ve put together a list of online topos. The first three are all very old and from the blocspenwith site, which no longer exists. They are out of date and not all that good, but at least they exist. The clodgy topo is much better and is the work of Barney Carver. The Rusty Peg topo of Priests Cove is also good as is the Tintagel topo.
Info for West Cornwall is pretty sparse, good or bad who knows, but there is little chance of that changing in the near future. Boulder Britain gives a smattering of info, but its not in detail and in some detail is wrong!
