Is the Mt. Whitney overnight permit lottery easier or harder to win than the day hike lottery?

The quotas differ meaningfully: 60 overnight spots per day versus 100 day-use spots. Both run through the same annual lottery, February 1 through March 15 for 2026, and both pools drew from the roughly 22 percent overall success rate in recent published numbers. The overnight pool is smaller, and it attracts a somewhat different applicant, so treat neither as an automatic backdoor to the other.

What the overnight permit buys you is physiology. Sleeping at Outpost Camp at 10,360 feet or Trail Camp at 12,039 feet breaks the 6,656 feet of gain into two days and gives your body a night to adjust before the push to 14,505. For anyone unsure how they handle altitude, that single night materially improves summit chances compared with a 2 am car-to-summit day.

The costs are pack weight and regulation. You carry a shelter, a bear canister, which is required for overnight food storage, and a WAG bag, since all human waste in the Whitney Zone gets packed out. Trail Camp is exposed and rocky, and it is the last water on the route.

Strategy-wise the same date logic applies as the day lottery: midweek and shoulder months of May, June, and October run far better than summer Fridays and Saturdays, and post-lottery cancellations return to the reservation pool all season.
