Less than a mile in is Alberta Falls, one of the park’s finest waterfalls, set among lush pine and aspen forest. From there, the trail goes steadily uphill, with frequent views to the mountains over the trees and into the cliff-lined gorge called Loch Vale. It steepens in a section of switchbacks, then comes to The Loch and traces the shore, granting views across the water to rock walls and glaciated slopes.

Beyond this lake, the trail is less traveled. It leads along a tumbling creek called Icy Brook, crossing on several small bridges. The gradient is mellow until just before Timberline Falls. A very steep section leads its base, then no easy way exists around the waterfall. The route is up a natural stone staircase that streams with water, requiring hand-and-foot scrambling on slippery rock. Proceed with caution, and turn back if the flow is too strong.

Triumphant climbers are greeted by the Lake of Glass, surrounded by stone and snow and only patches of stunted trees. The trail continues, but becomes tougher to distinguish among the boulders. The last half mile is slow going, but worth the effort, as long as the weather holds. Sky Pond is above the treeline, with rubble slopes and snowfields and granite walls encircling it. A row of giant spires rises on one side, and glaciers cling to 13,000-foot peaks on the other. With this dramatic backdrop, and at this elevation, the lake truly earns its moniker of Sky Pond.
