The path begins as a quiet, flat, single-track trail that meanders along the north side of the Adams River amongst large western red cedar and hemlock as well as lodgepole pine. This terrain will remain consistent for the next 1.6 km to the park’s main parking lot. Prior to reaching the main parking lot, you will come across a plaque dedicated to Roderick Haig-Brown, and just beyond the plaque is a bridge-crossing for an island loop trail. The island loop is an enjoyable 10-minute diversion from the main trail if you feel up for a side-jaunt.
The park’s main parking lot is a few minutes past the island loop bridge.
Out in the parking lot, look for the signs labelled LOWER TRAILS, which will take you across to the east side of the lot to Phil Rexin Memorial Trail. This path will regain the forest stroll through cedar, pine and hemlock. This is a walk in a magnificent forest with no sign of a river for 1.5 km until you reach a small bridge that crosses a minor stream.
A few minutes past the bridge, the trail meets a junction. The main loop continues on the left fork, while the right branch will take you to a closer look at the groundwater spawning channel. Another 500 m farther along, the trail encounters another fork; stay left again. Going right will return you to the groundwater spawning channel trail. Staying left at both intersections brings you back to the river and viewing platforms, and eventually takes you back to the main parking lot, completing a 2 km walk from the bridge.
There is a variety of minor side trails, loops and bridges used for watching the spawning salmon in the river, its back eddies and resting pools, but the way is always conspicuous and specified with signage, always directing you back to the main parking lot.
Back at the main parking lot, find your way back from where you came on the trail to the Adams River bridge.
