Let me add some additional information to Jim's posting.

The backpacker walkin sites are closed due to a major rock side last year. However, I think Jim maybe referring to the Ravine campground. The Ravine campground is located down from the overflow parking lot. You access the campground at the overflow parking lot. It is a walkin site built along the old road.

Below are some links: https://www.fs.usda.gov/recarea/inyo/recarea/?recid=20704 Notice at the top of the page, is says "Closed."

Here is a link to some info on the Ravine Campground: https://www.outdoorproject.com/united-states/california/whitney-ravine-walk-campground

A link to the Rock slide at the Portal last year: http://www.whitneyzone.com/wz/ubbth...ke-from-above-the-whitney-zone#Post57456 and here: http://www.whitneyzone.com/wz/ubbthreads.php/topics/57479

I would call the Inyo Forest Service to verify that the Ravine is open.

Please be advised that parking will be atrocious Memorial Weekend.
