Any others that are worth a visit within similar distance (ie. 40-50 mins by car)?
If there are any must do boulders/climbs that offer around the 7A-7C grade I'm also interested to hear about those too. Thanks in advance.
Tintagel North fits your bill perfectly. A bunch of really good problems 7a to 7c in a beautiful setting. Best in the evening sun with a calm sea
Hi Yep second vote for Tintagel for those grades. Grodrevy late after just check your visit lands with low tide after 2pm this will make sure access is good and the problems get time to dry in the sun, always nice to boulder with sand landings. Same with little Fistral not sure exactly the best tide window.
From Newquay I would also recommend Helman tor it is a more compact area than Carn Brea which unless you have been before can be difficult to find the problems and are a little spaced out. Both venues will eat your skin if you are not used to granite, and even then Helman has some of the sharpest crystals out there, but is one of my favourite venues.
Godrevy is excellent wave washed slate, but suffers from the beach crag problem of changing sand/pebble levels that mean climbs change grade or appear/disappear occasionally when there is a big storm.
Helman Tor is worth a visit, but my favorite when I visited Cornwall last year was Trewortha Tor:
A 15 minute walk in and no proper topo guidebook, but i found some fascinating problems of every style, on mostly solid granite.
Love it there and sure you will have a good time.
Godrevy is superb, a really good mix of problems and types of problems as well.
As mentioned, Little Fistral has some great climbing, but beware that some of the rock can be a little fragile in places; I've ended up on my backside when a crimp gave way on more than one occasion.
If you've got a car, also consider a visit to Roche Rocks: Roche Rock
