Honestly almost any of the more popular riding areas consist of an easy trail ride to the cabin and multiple beginner places to play in proximity to the cabin
Crowfoot is a great beginner area but a bit on the far side from Edmonton. Allen Creek has a nice short ride in and some good simple terrain around the cabin.
like sking, yer buds always take ya to the black diamond runs. a few easy area's before and around the lake. best to stay out on an overcast or snowy day, as the snow definition is bad,
