Rock Island Loops Map

Mesa Reserve is Boise’s best place for techy trail riding, with a purpose-built track among boulder fields on the side of Table Rock. The Rock Island trails even flip the typical etiquette, asking that all users yield to bikers on these trails only. They are riddled with natural and constructed rock features, plus a mix of banked turns and flowy track, all among elevated views over the city

Description

With a handful of trails in the network, multiple variations are possible. The route mapped here climbs on Tram Trail and Rock Island East, then descends Rock Island West to Rock Garden and back to Tram. The initial uphill is a bit burly, but then you’ll get full-on technical downhill the rest of the way. Expect moderate to advanced maneuvers, some of which are unavoidable and others optional. There’s a huge variety of features packed into these concise loops, so you could lap it more than once and try new moves every time.
