Fairly busy with pedestrian/hiker traffic on weekends; best ridden during non-peak times.
Spruce Mountain has a short climb up with a nice loop at the top. You'll find a few rocks and switchbacks to navigate but otherwise it's not a technical ride. Up top it has some nice views below that are worth stopping at to take a look.
This is a short ride so if you are looking for something longer you can link it up with the Spruce Meadow Trail to double your ride.
