To access the trail to Earnest Gruening from downtown Juneau, Drive out Glacier Hwy until Mi. 28. The Herbert Glacier Trail is 4.9 miles long and ends at Herbert Glacier.
The route starts from the well known Herbert Glacier Trail. Follow the trail (4.3 miles if you bike) 4.9 miles to the end of the maintained trail. From here follow the user trail on climbers left of the glacier to a large flat-ish area with huge pieces of granite bedrock at mile 7.2. There are some Ice Caves in the area that are interesting to explore.
From here the trail goes straight uphill to the North until treeline is broken. Continue uphill until a hanging glacier comes into view on climbers right.
Cross below the small hanging glacier heading North-East do a dark rust spot on the far side, then turn North and climb all the way to the top of the ridge.
Follow the ridge till it ends in a cliff. Downclimb some easy 5.2 through a crack on the right as you face the summit. Then climb up a 20' 5.6 wall to the top of the ridge. Some webbing and a rope is strongly recommended. From here continue down the ridge until forced onto the glacier on climbers left. Avoid the ice wall below you by hiking directly away from the summit and going down on more suitable incline, then strait along the top of the hanging glacier to the North side of the summit block.
Avoid more crevasses by continuing North and then moving uphill to the ridge. Continue south on ridge until rock in encountered. An easy 5.3 scramble to the summit with exposure and many loose rocks.

Webbing, a 20m rope, harness, crampons, rappel device, and a few carabiners. In addition dress appropriately. Mountaineering boots or stiff waterproof boots are necessary and gators help keep your socks dry. Having a SPOT or InReach is a great idea. Bring extra dry/warm stuff.
