The trail begins with a climb for 3 miles to Bingely Gap (elevation 4425 feet).
The forest service advises carrying water on the Lost Creek Ridge Trail, as hikers can't be assured that there will be water along the route. The trail is a total of 11 miles with elevation ranging from 1800 feet to 5700 feet.
After coming to Bingely Gap at 3 miles into the trip, the trail crosses into Glacier Peak Wilderness (4.6 miles). Eventually it will climb up along a ridge to an area of meadows and a "saddle" that looks down on Round Lake (12 acres, 5100 feet elevation). A side trail about 3/4 of a mile in length will take you down to the lake, where a few places to camp can be located among the trees.
Back on the main trail, you'll hike past Sun Up Lake (1/2 acre, 5300 feet in elevation) which is where the trail then becomes difficult to follow. The forest service reports "following boot tread, blazes and cross-country travel" are what is now required here.
This is not a good trail for early in the season travel, as the snow slopes can make finding the route difficult. This is a trail best for hiking late in the season, when the route is said to be a lot easier to follow, and a lot more enjoyable. You'll spot a number of lakes along the ridge, amid the trees.
This is sub-alpine hiking, as it takes you along the ridge through meadows encompassing large areas, open basins, and many different vistas and changing terrain. Finally, you'll pass by Hardtack Lake (.7 acre, 5450 feet elevation) and then reach Camp Lake (just under 10 acres, 5700 feet elevation).
A side trail climbs a knoll and descends into a rocky basin, and then descends even lower to Lake Byrne (51 acres approx., 5550 fee elevation). What a bonus to find such a large alpine lake at the end of the trail. The descent continues (if you so choose) to Kennedy Hot Springs and a junction with the White Chuck Trail (#643).
