Chocolate Lakes
Lake · Eastern Sierra corridor
Chocolate Lakes sits at 11,073 feet in the Eastern Sierra, a pair of alpine basins fed by snowmelt and ringed by granite. Wind-exposed and cold; conditions shift hour to hour.
Morning calm is rare but possible. By midday, wind funnels down from the peaks and peaks in afternoon. Temperature swings twenty degrees between sun and shade. Afternoon gusts can reach 40 mph. Plan shoreline activities before 11 a.m.; water-based pursuits favor early season when snowmelt is heaviest.
Over the last 30 days, the average wind here has run 12 mph with sustained gusts to 41 mph, and the average NoGo Score sits at 15. The week ahead will likely follow the same pattern: cold mornings near 19 degrees on average, sharp afternoon warming, and persistent wind by early afternoon. Crowding remains light at 3 on average. If calm water matters to your plan, Tuesday and Wednesday mornings typically hold better than weekend days.

About Chocolate Lakes
Chocolate Lakes comprises two interconnected alpine basins accessed from the Inyo County side of the Eastern Sierra, roughly 45 minutes south of Mammoth Lakes. The lakes drain into the headwaters of Rock Creek, which flows east toward the White Mountains. Vehicle access to the trailhead requires Highway 395 south to the Rock Creek Lake turnoff; from there, follow Forest Service roads to the staging area. Snow and washout close access in winter; confirm conditions before driving the unpaved final segment. The setting is unshaded, rock-bound, and fully exposed to westerly wind flows off the Sierra crest.
Chocolate Lakes sits in the rain shadow of the Sierra Divide, receiving less precipitation than Yosemite Valley but more snow than the Owens Valley floor. Year-round temperature extremes range from 5 degrees in winter to 32 degrees in summer. The 30-day rolling average wind is 12 mph, but gusts to 41 mph are routine in the warmer months when thermal convection is strongest. Spring and early summer bring snowmelt and the highest water levels; by late summer, the lakes shrink and clarity improves. Crowding is minimal year-round; the remote trailhead and high elevation keep visitor pressure low. Fishery seasons overlap heavily with snow-free access, typically mid-June through October.
Chocolate Lakes suits backcountry anglers, off-trail scramblers, and ultralight campers willing to carry water. The high elevation and wind exposure are not forgiving; afternoon wind can make paddling dangerous and shore camping difficult. Water temperature remains cold all season, averaging below 50 degrees even in August. Experienced visitors plan for one full day at the lakes and stage a camp lower in the Rock Creek drainage for a more protected second night. Parking at the trailhead is limited; arrival by mid-morning is necessary on weekends. Smoke from Sierra fires in summer and fall can reduce visibility and air quality significantly.
Rock Creek Lake, lower in the same drainage, offers similar fishery and more shelter from afternoon wind. Crowley Lake, 30 minutes south on Highway 395, is more developed, larger, and busier but warmer and calmer in afternoons. Convict Lake, west of Mammoth Lakes, sits at lower elevation with softer weather and better afternoon conditions. Chocolate Lakes appeals to visitors seeking alpine solitude and cold-water fishery; it is not a destination for weekend crowds or calm-water certainty.
