The Parker Lake Trail in the Ansel Adams Wilderness might be the best effort-to-reward ratio of any mountain hike in the Eastern Sierra. The destination is a glacially carved lake with water so clear it carries a faint turquoise tint, framed by rugged Sierra peaks. But if you slow down and look closely, there's a whole other hike happening alongside the scenic one. Early summer is when wildflowers push through dry scrub, bees move between blooms, and streams run full with snowmelt. I hiked to Parker Lake at the start of July and paid attention to the details. Here is what I found.

The Twenty Lakes Basin Loop is a stunning hike that begins at Saddlebag Lake and leads you through a series of breathtaking alpine lakes and scenery. Along the way, you'll be treated to impressive views of nearby mountain peaks. In this article, I’ll take you along with me on this hike, which I did in late summer after a particularly snowy winter. The lingering snow patches, which persisted until September, made the hike both tricky in places and exciting.
