Lovely trail across a massive granitic/volcanic mount down to the lake.
Not sure why it's listed as being best from Jul-Aug, but I thought June was beautiful. Clouds and thunderheads do gather in the afternoon in the Sierras in early summer, but a morning hike here was awesome. Lot's of wildlowers across the scrabble and in the granite fissures. I actually saw Lewisia spp. which is hard to catch due to it's very short blooming period before disappearing completely.
More than half the trail is readily apparent, with the rest being pretty well marked with cairns (small stone piles) on the open granite. That being said, it would be easy to get off trail if not paying attention, which is easy to do with the fantastic views!
I think the overall elevation change listed is probably correct based on the starting and ending elevation, however, the trail rises to a ridgeline (7680+) and then drops down to the lake (7200), making the total change over 400.
Will definitely do this one again when I just need a short outing.
