In reply to Cornish Cream:
Being honest i spend alot of time at high sports, but it is a great wall for top roping and leading. The barn is definately a great place to go bouldering and atmosphere but i haven't been for a while.
As mentioned its worth checking them both out, and making your own mind up about them.
The barn definately has a set of very loyal and dedicated members, and some great boulder problems.
However High Sports can definately hold its own, and route sets happening once a week, yes it is slightly more expensive. but has far more selection of routes.
but i guess a key feature is that it has great public transport access from all over devon and cornwall whether coming by bus or train..
Happy climbing, and hope to see you on the crag, when this weather improves.
