In reply to dl_wraith:
Then I would advise taking a wide range of clothes! It can be boiling hot in October, or quite chilly and rainy, so be prepared for either. Think about what you will do if the weather isn't right for climbing, but also make sure you take a sun hat, sun cream etc!
You will have a great time, wherever you go and this holiday will probably be the first of many!
We've usually hired a car, to make it easy to visit different crags.
I love October as a time of year to go away, but can't go in the autumn because of my work, so I am quite envious.
