Two new guides should be on the shelves now for the summer which may help promote a resurgence in popularity on limestone in Northern England. The heavyweight offering from Rockfax is their biggest guide ever with 384 pages and over 2400 routes. It covers crags from Dovedale in the south to Chapel Head in the North. More Info. The second guide comes from the BMC and is a small book dedicated to the small sport climbing crags and quarries in the Peak District. More Info.
