You will not regret it. Not even if it's chucking it down and blowing a gale.
It's also got the added bonus that you have to tromp across Chatton Hill to get there.
hehe
I think I've been there in most weather conditions, and I've taken quite a few newbies.
I once tackled it in August, with waist-high bracken. We got soaked. Also almost dropped down one of the badger holes!!
Always, always worth it.
And the view from Chatton to the Cheviot is yummy.
