http://www.walkhighlands.co.uk/Forum/viewtopic.php?f=17&t=3231This topic lists a lot of clubs, not all associated with MCoS. I'm a member of the Perth Hillwalking Club and guests and new members are always welcome
You can get the web link from the above topic or search Perth Hillwalking Club
When I first joined the club I had very little hill experience and it was a great way to learn from others and I've also met friends who I now walk with at other times as well as on the club walks.
I guess clubs will vary in their style but we put on a bus oince a month with 4 or 5 different walks of varying levels. Having the bus means that we can do linear walks and so don't have to return to the same start point. On Sunday we had a very hot walk from Glen Nevis to the ski centre a couple of groups going up to the half way lochan on the Ben Nevis track and down to the ski centre with 2 other groups going over Aonach Beag and Aonach Mor.
I found everyone very friendly and welcoming when I first joined and I'm sure other clubs are as well.
