Id strongly recommend looking for an Explorer Scout group- it's how I learnt most of my moutain skills.
Although this doesnt always work as planned, Explorer units are meant to be run by the district, so people from over a wide area can meet and pick and choose the activities they want to focus on, with like-minded people. I was very lucky to be in a unit with two ML qualified leaders so we did a fair bit of backpacking and wild camping. I stayed with Explorers until I was 18 last summer, and now at uni I've managed to get well involved (im the newly elected captain) of the hillwalking club.
