Carlon Day Use Area
Campground · Yosemite corridor
Carlon Day Use Area sits at 4,409 feet in the Yosemite corridor's Sierra Nevada, a forested staging point for Tuolumne River access. Protected from high-country exposure, it runs calmer than the open ridges to the east.
Wind averages 7 mph but gusts to 21 mph by afternoon, funneling up the river canyon. Morning conditions are substantially calmer; head out early if paddling or fishing. Crowding remains light relative to Yosemite Valley entrances. Smoke from upstream fires can settle in the drainage in late summer.
The 30-day average wind of 7 mph and NoGo score of 15 reflect late spring stability as snowmelt tapers and thermal winds build predictably. Temperatures average 45 degrees Fahrenheit across the month. The week ahead should track normal patterns: calm mornings, rising wind by afternoon, and manageable crowding unless a holiday weekend coincides.

About Carlon Day Use Area
Carlon Day Use Area occupies a riverside clearing on the Tuolumne River drainage in the Yosemite corridor, roughly 30 miles northwest of Yosemite Valley via Highway 120. The site sits at 4,409 feet elevation, well below the alpine zone but high enough to catch Sierra weather. Access is straightforward: drive Highway 120 toward the park, turn onto the Forest Service road signed for Carlon, and park in the day-use lot. The area serves primarily as a launch point for river activities and a quiet alternative to the crowded valley floor. Base popularity remains low (0.3 relative index), meaning even busy weekends see far fewer visitors than Yosemite Valley or Tuolumne Meadows.
Conditions at Carlon track the Tuolumne River drainage and the north-south canyon orientation. Wind averages 7 mph over the rolling 30-day period but regularly reaches 21 mph by mid-afternoon as the canyon funnels thermal circulation off the high Sierra. Morning hours, especially before 10 am, offer the best stability. Temperature swings from lows near 33 degrees Fahrenheit in late winter to highs around 62 degrees in summer, with the 30-day average currently at 45 degrees. Crowding averages 12 on the rolling 30-day index, substantially lower than Yosemite Valley outlets. Late spring and early summer bring rapid snowmelt that can raise river levels and complicate access. By late August and September, upstream fires occasionally funnel smoke into the drainage, reducing visibility and air quality.
Carlon suits river runners, anglers, and picnickers seeking solitude close to Highway 120. The site has no formal campground loops, only day-use parking and river access, making it ideal for half-day outings or overnight car camping elsewhere with a daytime excursion. Experienced paddlers use Carlon as a put-in for Tuolumne sections; expect high water and cold temps through June, lower flows and warmer conditions by August. Afternoon wind makes paddling challenging after midday. Anglers target the river itself; shade under ponderosa pines moderates temperature swings. Parking fills quickly on holiday weekends but rarely during the work week. Bring plenty of water; amenities are minimal.
Nearby alternatives include Hetch Hetchy Reservoir, 20 miles north via Highway 120, which offers larger day-use facilities and lake rather than river access; Hetch Hetchy sits slightly higher and often sees stronger wind by afternoon. The Tuolumne Meadows area lies east on Highway 120 but involves a longer drive and encounters high-country wind much more frequently. For those avoiding the Yosemite corridor crowds entirely, the western Sierra foothills near Don Pedro Reservoir offer similar elevation and dramatically lower traffic. Carlon's combination of low popularity, river-focused activities, and straightforward access makes it a strong choice for paddlers and anglers who time their visits to calm mornings.
