Scenery-wise, the Sentinel Pass Loop is truly hard to beat. This route offers some of the most breathtaking views in the entire Canadian Rockies. You’ll run right beneath the imposing north face of Mount Temple and past a stunning array of rock spires on the north side of Sentinel Pass, including the dramatic Grand Sentinel. Along the way, you’ll catch glimpses of the iconic Moraine Lake and the majestic peaks that frame it.

The running itself is equally rewarding. Most of the trails are well-maintained and highly runnable, making the journey smooth and enjoyable. However, the north side of Sentinel Pass presents a challenge. Although there is a trail through this section, it can be difficult to follow and often remains covered in snow late into the season due to its shaded aspect and high elevation. When snow lingers, this portion becomes less of a running trail and more of a mountaineering route. Tackling it safely may require crampons, an ice axe, and mountaineering expertise. Because of these conditions, it’s best to plan this route for mid-July or later.

Getting to the trailhead is arguably the crux of this adventure, thanks to the popularity of the area. The two best options are taking the shuttle bus directly to the trailhead or parking at the Upper Lake Louise lot and running a roughly 5 km connector trail to the Paradise Valley trailhead. Keep in mind that parking at Lake Louise often requires arriving around 5–6 AM to secure a spot, along with paying a $37 fee. The connector trail is primarily used for horseback riding, making it rutted and adding nearly 10 km round-trip—not exactly the most pleasant segment for runners. The bus, though more convenient, does require booking in advance.

It also makes good sense to treat the run as a point-to-point from the Paradise Valley trailhead to the Moraine Lake trailhead. There’s no wrong choice here, but the Moraine Lake Highline Trail connecting the two is a gem—smooth single track with fantastic views from open clearings and avalanche paths.

Running the loop counter-clockwise is recommended. It gives you the most enjoyable downhill stretches and orients you perfectly for soaking in the best views. This route combines everything: challenging terrain, unparalleled scenery, and a memorable alpine running experience.
