This route ascends old coal exploration trails into the alpine, then climbs the ridge to the summit of Mt. Kostuik. After 2 km, the trail levels out and enters subalpine meadows. From here, you can scramble up to the ridgetop and head for the summit, which is composed of conglomerate, a rock type with pebbles and cobbles. There are excellent views, especially to the south, where peaks of Monkman Park are visible. Anglo American’s Trend coal mine is visible to the east. Roman Mountain, the highest summit in the area, has a syncline or downfold in the strata.

The subalpine meadow and alpine areas have interesting rock formations Once in the alpine, excellent views of the surrounding mountains are presented with better and better views all the way to the summit. A descent through Hidden Valley provides a different more forested experience.

From the parking area head up the dirt track to the west. After 100 m, turn right, following this road which climbs steadily. After 2 km, the trail levels out and enters subalpine meadows.

This route can be combined into longer hikes, like a route from the top of Mount Kostuik, exiting on the Hidden Valley route. For a full day hike, drop a vehicle off at Five Cabin Pass, start hiking on the Mt. Kostuik route, then keep going south along the ridgelines (known as Windy Ridge) to the Terminator, dropping down to your vehicle.

From Tumbler Ridge, drive south on Hwy 52 E (Boundary Road). The paved road passes the turnoff to Kinuseo Falls at km 12.7; keep going straight on Hwy 52 E for 6.8 km to a right turn onto the Core Lodge Rd. This road is radio controlled - watch for industrial traffic. At 12.5 km, there is a fork. Take the right fork, following the sign saying “all other traffic”. The left fork is for mine traffic only. From Hwy 52 it is 14 km to the Core Lodge.

The key to access these hikes is the Five Cabin road, which heads south from the Core Lodge and is passable as far as km 8. This rough dirt road is suitable for 2 wheel drive vehicles in dry weather, but a 4X4 is needed in wet conditions.

To reach the trailhead, drive south from the Core Lodge on the Five Cabin road for 0.6 km and look for the sign for Mt. Kostuik. Park here.

Hiking The Terminator is only suitable for experienced hikers with good route finding skills. The alpine ridges are often windy, and fog may roll in unexpectedly. Take a map and compass, and know how to use them.

These routes are in bear country; travel in groups and make noise.

Please pack out what you packed in.
