There are a dozen or so parking spaces right at the trailhead. There is a parking lot maybe 50 yards away and a larger â€œoverflowâ€ lot a few minutes further than that. You can park as long as you like. There is a clearly-marked â€œday use onlyâ€ parking area past the trailhead. Donâ€™t park there. Bears can be a real problem around Whitney Portal. Take all the warnings seriously.
