Accessing this hike from Glacier Basin Campground was super simple. Just a half mile walk to the Bierstadt Moraine trailhead at the Park-and-Ride. I hiked counterclockwise and chose to take the shuttle back from Bear Lake to the Park-and-Ride at the end, but you can complete the loop on foot by turning east just before Bear Lake or, if you’re headed back to Glacier Basin Campground, you can follow the Glacier Creek trail from the Bear Lake trailhead.

The trail is clear for most of the route and water is flowing strong in all water sources.

There were several easily passable blowdowns on trail between Mill Creek and the intersection with the Firn Lake trail intersection.

The section between Odessa Lake and Lake Helene/Two Rivers Lake has several steep icy snowdrifts completely obstructing the trail. These sections have minimally defined foot placement – don’t rely on these being present/usable due to arrival of monsoonal rains. I definitely would not recommend attempting this section without poles and spikes before these drifts melt out.
