A shorter singletrack flow trail, less swoopy than the Outer Loop.
Brief closure during spring break-up.
Dogs: Leashed
The Inner Loop is a shorter trail of the Ester Dome Singletrack Happy Valley Trail System. Snaking its way around a forested loop on a south-facing hillside, this trail strikes a balance between winding forest singletrack and bermed-earth "bike-park" features. It also has a couple of smaller jumps and rock obstacles.
Similar in design to the Outer Loop, the trail bed is smooth and everything is do-able for a biker with intermediate skills. The trail runs mostly through open aspen forest with occasional forays into denser stands of mixed spruce and birch. Lots of squirrels and songbirds in the area, but especially keep watch for the occasional moose.
Take care at the intersections, as there are several. Look for the signs and colored reflectors (Inner Loop = Yellow, Outer Loop = Orange, TnT = Green). The Inner Loop and Outer Loop meet three times.
