A singletrack flow trail that is very swoopy.

Short closure during spring break-up.
Dogs: Leashed
The Outer Loop is the longest 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. Similar in design to the Inner 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, the Equinox Marathon Trail crosses over the easternmost end of the Outer Loop, and the Henderson Drop-In meets the trail near its highest and westernmost point.
