12 mile trailhead:
The southernmost trailhead is on a spur road just south of the 12 mile marker on the Richardson Highway. There is a brown “Pack Trail of 1899” sign marking the road, on the left side of the highway if you are driving away from town. Shortly after the turn, there is a small pullout across from a stream. There is a very well travelled social trail right at the stream that dead ends shortly. The trail is several yards down the road, on the left as you are heading away from the highway. It has a small sign that says “Trail.”
Hazards: black bears, some muddy sections, some exposure
The trail starts in a lush forest. There are large spruce trees, watermelon berries, blueberry bushes, soft mosses, and beautiful little streams. This area is a good place to forage for fiddleheads in the spring, and in the summer the profusion of ferns give the area a prehistoric feel.
This section of trail features many interpretive signs that are genuinely interesting. One sign helps viewers to spot original pieces of trail construction from over 100 years ago. Others contain original accounts of people’s experiences in the early twentieth century.
After a few switchbacks, the trail plateaus. As Keystone Canyon comes into view, the hillside drops off steeply just off the trail, creating some exposure. It is easy to imagine this would be extremely difficult for travelers with fully loaded horses.
Once the trail is in Keystone Canyon, it offers terrific views. You can see much higher up Bridal Veil Falls from the trail than you can from the highway. You can also watch kayakers and rafters float down the Lowe River. Behind you, there is a view of the Lowe River. and Meteorite Mountain.
A steep spur trail leads downhill to the Keystone Canyon trailhead, while the main trail continues onwards.
Keystone Canyon (14 mile) trailhead:
The Keystone Canyon trailhead is very difficult to see while driving, but the pullout is unmistakeable. The trailhead is located between the Bridal Veil Falls pullout and Horsetail Falls, just south of mile 14. Park in the large pullout on the west side of the road used to view Bridal Veil Falls. At the southern end of the pull out there is an interpretive sign describing the “Goat Trail.” Right at the sign, a path leads through the vegetation parallel to the highway to the south. Just before the rocky cliff, the trail turns away from the highway to the right and climbs uphill.
Hazards: black bears, some slippery steep spots on the spur trail between the trailhead and the main trail, wet feet at one stream
This section of the trail is solidly in the transition zone between the lush rainforest at 12 mile and the true alpine tundra at 25 mile. There is not much here for foragers, but there are some good views of the surrounding mountains and some pretty streams running down the canyon sides. The vegetation is mostly alder.
