Good for rainy days
Although Indian Spring Trail offers no spectacular views, does not follow the course of a mountain stream, is not physically challenging and does not traverse particularly beautiful alpine landscape, it is worth considering for a few reasons. Foremost among these is its all-weather surface. Most of the trail lies atop a cindered railroad grade or has been gravelled, making it a good rainy day choice. Its located just south of Big Lake, with a spur running up into one of the campgrounds and another branch connects it to West Fork Trail #628. And despite the concentration of people and traffic around Big Lake, elk and other game frequent the woods and meadows around the trail.
Proceeding south from the trailhead, one reaches the turnoff to Big Lake lookout in half a mile. The side trip up Big Lake Knoll is worth the effort as it presents the only steep grades of the hike, passes through a grove of aspens of considerable size and offers some nice long views toward Mt. Baldy from the tower stairs. Back on the main trail, in another mile one arrives at Spillman Spring where a series of hand hewn troughs forms a sort of flume that carries the flow from the spring to nowhere, really. This area was logged many times over so no old growth forest remains but a few second growth trees, primarily firs, along this section of trail are reaching maturity and respectable size. Three miles from its beginning the trail passes Indian Spring. If cattle were not allowed to tramp around at will, the site would probably be quite attractive; but in fact, except during the wettest seasons, water rarely shows here and it's identifiable only by the taller and greener grass. In another mile the trail joins the abandoned rail bed and turns back north for about three miles. Midway along this section a connector trail branches left to West Fork Trail. If shuttling between trailheads is possible, one can combine Indian Spring, West Fork and Thompson Trails into a single 11-mile hike that progresses through increasingly lovely terrain ending on the bank of a mountain stream in a drop-dead gorgeous valley.
