There is also the Septimus trail system a.k.a. Stewart Lake trail system.
This is a very easy going trail most of the time depending on where you're going as there are different trail branches. Early in the season you can find lots of muskeg but it tends to dry out over the summer, unless it raiins for a few days.
I would not suggest the Beatton trails if you are not an experienced rider. Very steep hills and tricky off camber trails.
And no, you don't have to be a member of a club to ride any of the trails here. They are open to everyone, just pack out what you pack in.
