Source: Club Tread: Starting from the road junction, hike up the left branch road as it climbs uphill for a short distance before quickly leveling out. The trees along either side of the road will gradually close in until nothing more than a path is left. Less than 500 meters from the start (10-15 minutes), carefully watch for flagging tape on the right. Be warned that the flagging tape is extremely easy to miss and marks the point where the trail leaves the road and begins to climb up a talus slope. Turn here and climb up the talus, following a cairned route that leads up and a little to the left.
Shortly after, the trail enters a relatively dark forest, leading along a faint but easy to follow path. Your time in the forest is limited before the trail climbs out onto a logging road. Turn left, heading down the road. Note that if you have access to a high-clearance 4×4 vehicle, it is theoretically possible to drive to this location. However, the condition of the road is very rough – even the toughest truck will not be able to make it much further.
After approximately 15 minutes of hiking along the logging road, you will be rewarded with a fantastic view of Harrison Lake. Take a break here if necessary, and then continue along the road as it heads north and into the dark forest. It is important to note that the road is decaying rapidly, with a few sections of ground that have been undermined and bridges that are decaying. Watch your step! Some of the holes beneath the road are more than 10 feet deep. When the first junction is reached, take the right fork. Beyond the junction the road is overgrown, now nothing more than a wide, grassy path.
The road will eventually reach a location where it has been completely washed out by a creek. At this point you must locate flagging tape in the forested area to the right and immediately before the creek. The true trail to Slollicum Peak begins here, now permanently leaving the old road. Unless you are planning to hike to Slollicum Lake, don’t continue down the road beyond the washout.
Beyond the old road, short switchbacks lead up a forested ridge. The forest thins out as the trail climbs, offering a few interesting views of a small creek that runs down to the left. After a steep 250 meters of elevation gain from the road, a small rock bluff is reached at the base of a replanted clear-cut area. The unfortunate lack of mature trees in the area allows for a fantastic view of Harrison Lake.
A flagged route leads through the clear-cut, eventually reaching the side of a deep gully. Climb down to the small creek at the base of the gully before scrambling up the opposite side and into a beautiful old growth forest. A lack of underbrush in the old growth can make finding the trail a challenge in places, but for the most part it is well marked and easy to follow.
After passing through a meadow with a babbling brook, climb up a series of steep, grassy hillsides. The tall grass has completely overgrown the footpath, making route finding more difficult. Carefully look for the small pieces of flagging tape that mark the point where the trail re-enters the forest after each section of grassy hillside.
Less than five minutes later, you will reach the crest of Slollicum Peak’s ridge. Make a sharp 90-degree turn to the left, following a faint route marked with blue flagging tape. Slollicum’s forested first peak is reached almost immediately, offering great views of Slollicum Lake and the surrounding area.
Continue following the rough and overgrown trail, still marked with blue flagging tape, as it leads north along the crest of the ridge to the main summit. The summit has a large cairn at the top and offers the hike’s best view – a full 360 degree panorama of Harrison Lake and its surrounding area.
