One of the hardest things about this hike is getting parking space! We got up at 5:00 to get a space at Logan Pass which was filling up by 7:30 or so. (The Current Conditions page on the park website and the Logan Pass webcam are good resources for timing your visit.) Once parked we took our time with breakfast, coffee, and restrooms before hitting the trail.
The trail starts on the opposite side of Going-to-the-Sun road. In the photo below left you can see the more obvious line of Going-to-the-Sun road and above it a fainter line that is the Highline trail.
After crossing an alpine area the trail is carved out of a rock cliff. Though narrow it’s still possible to pass other hikers in either direction if you’re careful. Which is good because this hike is popular.
Once beyond the rocks, the trail is still narrow but at least it’s not a bare cliff.
We went a little over a mile. Enough to see some great mountain views and a couple of springs on the trail.
We also saw mountain goats and bighorn sheep on the slope opposite. The photos below are of the sheep. (Look for the five white dots. Those are their butts.)
After we finished the Highline hike we went across the road and did the Hidden Lake Overview hike. So we didn’t have to get up at 5:00 again to get a parking spot!
