Coliseum Mountain with its “cap” gives you 360-degree panorama of the foothills and Rockies, making this a classic hike in Alberta’s West Country.

One of the most popular hikes in Nordegg to the distinctive summit overlooking the town. This trail guide is for the official trail. There are two other options to reach the summit and we’ll add these here at some point in the future.

Coliseum Mountain dominates the skyline by Nordegg at 2040 metres high. The mountain was possibly mentioned in a map sketched by Sir James Hector showing the route taken by the Palliser Expedition in 1858.

Martin Nordegg claimed to have climbed the mountain in 1913 and by 1925 a fire lookout, the first in the province, was built on the mountain. Today, only a pile of rubbles is left of it and the active fire lookout is on Sunda Mountain to the north.

Trailhead: The Coliseum Mountain Trail Staging Area is located in the Nordegg North subdivision. From highway 11, follow Shunda Creek Road and keep right onto Baldy Mountain Road. Take the next right on Eagle Drive. The trailhead parking lot is at the end of the street. Dry toilets are available at the trailhead.



  • 0.3 km | Stream crossing
  • 1.3 km | Old access trail
  • 4.3 km | Viewpoint and scree slope
  • 6.3 km | Summit viewpoint and old fire lookout


  • Retrace your steps back to the trailhead


From the trailhead parking lot, follow the signs to the Coliseum Mountain trail. The first section of the trail is newer having been built after the new subdivision and making the hike a few kilometres shorter.

The only stream crossing on this hike is near the beginning. The rest of the trail is dry and usually in great condition.

After 1.3 km the trail reconnects with the older trail. From there it’s a steady ascent with switchbacks making it easy to gain most of the vertical on this hike. Along the way the views starts to get better with glimpses of what’s to come.

The trail eventually levels off after 4 km where there is an informal campsite and great views of Nordegg and Abraham Lake. The trail continues across the scree slope and then along the ridge toward the site of the old fire lookout, another 2 km away.

Hiking along the ridge gives the opportunity for spectacular views of the mountains to the east, the Brazeau range and the forested area to the east.

The last step is to ascent the cap where a trail takes you through the cliff band to the summit. The 360 degree views makes it obvious why this was chosen as a fire lookout in the 1920’s. Sadly little remains of the fire lookout, except for a few concrete blocks and metal pieces.
