Three days in cornwall... advice needed

Im off there next week. Also looking for some good routes if anyone has any. North cornwall to anywhere within 60miles and a train back to somewhere recognizable

I go to the Launceston area a couple of times a year and try to work out routes from the map before I go.

For me the big issue is that there seems to be a choice of either single track roads with grass in the middle and a ton of cow shit (it always rains in North Cornwall!) plus gravel and pot holes or bloody fast A roads. Quiet good condition B roads are around but not necessarily in a nice loop.

For that reason I generaly take my mountain bike. This is not such a bad idea as the area is extremely lumpy. A 50mile route generaly gets about 2k of climbing.

This is quite a nice route around Bodmin North Moor (easy enough to work out) though fog can be an issue.

Also it's possible to take the Camel trail down to Padstow from quite far away.

The narrow lanes are bounded by what look like hedges but are in reality stone walls covered in green. That blind corner at the bottom of the 15% descent might have a rushed tractor in harvest or a lost 4x4 with howling kids so take care.

For all that it's a great training area!
