Vacation Pass
Peak · 12,837 ft · Eastern Sierra corridor
Vacation Pass is a 12,837-foot peak in the Eastern Sierra's high country, sitting well above treeline with minimal shelter from afternoon wind.
Wind dominates here. Morning calm typically breaks by late morning as thermals build, funneling down drainages and across the exposed ridgeline by afternoon. The 30-day average wind runs 12 mph, but gusts regularly exceed 40 mph by 3 p.m. Plan for exposed, cold conditions even in late spring.
Over the last 30 days, Vacation Pass averaged a NoGo Score of 36.0, with temperatures holding around 16 degrees Fahrenheit and average wind at 12 mph. The coming week should hold similar patterns: expect afternoon winds to peak and morning windows to close quickly. Watch the 7-day forecast for any dips below the 36-point rolling average.

About Vacation Pass
Vacation Pass sits in the high Eastern Sierra corridor, accessed from the north via Highway 395 south of Mammoth Lakes or from the west via Highway 120 near Lee Vining. The peak lies on the crest of the Sierra divide, exposed to both westerly storm systems and upslope afternoon winds channeled by the Mono Basin to the east. The approach involves high-altitude scrambling above 12,000 feet with minimal protection from weather. Most parties access via the Inyo National Forest road system or cross-country from neighboring peaks in the Mono divide.
Conditions here are severe year-round due to exposure and elevation. Winter brings deep snow and substantial avalanche terrain on the eastern face; spring melt creates slab instability through late May. The 365-day record shows temperatures ranging from minus 2 to 36 degrees Fahrenheit, with maximum wind gusts hitting 43 mph. Summer (late June through August) sees the calmest conditions and lowest crowding, but afternoon thermal winds still build predictably. Fall rapidly transitions to cold, and by early winter the location becomes an avalanche concern without stable snowpack and proper assessment.
Vacation Pass suits experienced scrambler-mountaineers and peak baggers comfortable with exposed terrain, navigation, and self-rescue. Most visits occur in July and August when snow melts and afternoon wind, though still 12 mph on average, remains more manageable than spring and fall. Parking is limited; trailheads fill quickly on weekends. Arrive before dawn to secure a spot and maximize your morning window before 10 a.m., when wind typically accelerates. Carry extra layers, water, and a map; cell service is unreliable.
Neighboring alternatives within the same corridor include Mount Tom (13,652 feet) to the south, which offers similar exposure but slightly more defined approach trails, and Glass Mountain (11,513 feet) to the north, which is lower and calmer. For climbers seeking comparable elevation with better weather windows, Mono Basin peaks directly east across Highway 395 (like Grayling Lake area summits) trade exposure for proximity to paved access. The Eastern Sierra corridor's high-altitude character means all these peaks follow the same 12 mph average wind pattern and require the same avalanche terrain awareness in winter.
