Hilton Creek Trailhead
Trailhead · Mammoth Lakes corridor
Hilton Creek Trailhead sits at 7257 feet in the Mammoth Lakes corridor of California's eastern Sierra Nevada. A jumping-off point for high-country travel, it typically runs cooler and less crowded than valley alternatives nearby.
Wind averages 11 mph here, accelerating noticeably in afternoons as thermal and pressure effects funnel through the drainage. Morning calm is the rule; by mid-afternoon, gusts routinely exceed 15 mph. Snow persists longer at this elevation than at trailheads below 7000 feet.
Over the last 30 days, the average NoGo Score was 16.0 with wind holding at 11 mph and temperatures averaging 39 degrees Fahrenheit. The week ahead will track typical spring patterns: warming highs and persistent afternoon winds are standard. Crowding remains light at 16.0 out of 100 on average, making this an uncrowded option even during popular windows.

About Hilton Creek Trailhead
Hilton Creek Trailhead is located off US 395 in the Mammoth Lakes corridor, approximately 45 minutes north of Mammoth Lakes town itself. The trailhead serves the Hilton Creek drainage and adjacent high-country routes in the Sierra Nevada backcountry. Access is via a short rough spur from US 395; the road is passable in most seasons but degrades in soft snow. The nearest gas, food, and lodging cluster around Mammoth Lakes to the south or Lee Vining to the north. Elevation at the trailhead is 7257 feet; nearby ridge crest peaks top out near 11000 to 12000 feet.
Conditions at Hilton Creek reflect typical high-Sierra patterns. The 30-day average temperature of 39 degrees Fahrenheit means snowpack persists well into late spring; expect wet slab conditions and creek crossings that are treacherous in early mornings. Wind averages 11 mph but the 30-day maximum recorded was 27 mph, indicating strong afternoon thermals that funnel down the drainage by late morning through evening. Crowding averages 16.0 out of 100, making it genuinely uncrowded compared to famous Mammoth basin trailheads. Summer brings calmer, warmer conditions; winter access depends on US 395 road conditions and avalanche hazard in the peaks above.
Hilton Creek Trailhead suits backpackers and high-country scramblers targeting remote Sierra Nevada passes and drainages. The low crowding (16.0 average) means solitude is the primary draw; experienced parties use this as a launching point for multi-day traverses. The persistent wind and early-season snow demand solid mountaineering judgment. Parking at the trailhead is limited but rarely fills; arrive mid-morning if you're hiking on weekends. Skip afternoons if you're climbing exposed ridges; the 11 mph average wind and afternoon acceleration make exposed terrain unpleasant after noon. Water is reliable in the creek drainage early in the season; upper terrain dries quickly by midsummer.
Nearby alternatives include the Mammoth Lakes Basin trailheads to the south, which are warmer, more crowded, and better-maintained; and the June Lake Loop access to the north, which sits slightly lower and offers more moderate creek crossings. Hilton Creek Trailhead is the choice for parties seeking silence and higher, more rugged terrain over tourist infrastructure. The corridor as a whole sees heaviest use midsummer and again briefly in early fall; Hilton Creek remains quiet year-round due to its remote drainage and rougher approach.
