hi Gail
I met you in EPC many years ago and later in the Gunks. I live in EC and would be happy to tell you about the climbs, crags and the area if you would like. You could PM me your number and I can call or whatsapp. I would also be happy to show you around once you are here if you would like
Grades here are very soft. 6b or 6b+ is comparable to Gunks 5.9 or 10a at most. there are 3 nice 5s at Cocina, only 1 good 5 at Castrojo
Alan's sector recommendations are good but the routes at Castrojo and Cocina are mostly 30-35 meters, there are a few 20-25 m. Castrojo does have 4 short 5s, The Rockfax guidebook is the only good one but it has many errors so beware what is shows for anchors, route paths and grades
For rental cars, look at doyouspain.com. much cheaper than the car rental websites
Do you have a place to stay?
When will you be coming? the season and weather greatly affect which crags are good on any day
if you want to walk the caminito, make reservations ASAP because it often sells out way in advance
