In reply to Ben Taggart-Ryan: For quite a few climbs at Cheddar the season finishes in mid March ...if you wait till May/June classics like Stone Cold Fever and Coronation Street will be out of bounds till Autumn.
Make sure you are aware of the access arrangements if you climb there (see the BMC regional access database or refer to the guidance in Martin Crocker's 2009 Cheddar Gorge Climbs).
