Lookout Mountain, aka Galbraith Mountain, is an extremely popular Bellingham Washington tree farm trail system.
Certainly not a destination trail system but well worth visiting for a day trip, with some XC terrain accessed from the Birch Street TH and an ever-expanding collection of stunts and wild, hand-built terrain at the southern end of the trail system.
The maps don't reflect every single trail and degraded trails are occasionally shut down. Please respect the signage and note that this tree farm is actively logged, with closure notices posted.
Whatcom Independent Mountain Peddlers Society (WHIMPS) works with the Trillium Corporation for MTB use of the tree farm.
Although there are no defined loops, the two defined on this page are commonly ridden and show a typical terrain profile for most rides. It's possible to hook up enough terrain to ride 15mi, but 10mi rides are more typical.
The southern 'Galbraith Lane' terrain is steeper and made more technical by the construction of stunts and ramps. Due to the stunts, many of those trails are intended to be ridden downhill, so try to use the area south of RD2000 as downhill-only.
The local bike shops usually are the best source for the latest maps, or just go out and see what there is to ride.
