Best place for 'yocals', 'pointies', 'webbies' & best Kebab in Nwales is Llanwrst. Be sure to get a 'run ashore' at Llandudno!!
Best AT experience......France!
Use Camping des Cinq Valles, Saint Blaise, Briancon as a base camp with lots of top kayaking, sports climbing & full on mountaineering close by!! Also a few good 'Via Ferrata' routes for more relaxed days.
Top place to go if you can get it off the ground!! It is worth the V long drive!
