These camping spots fill up pretty quick in advance. But we checked for cancellations and got lucky because the storm was coming through in a bunch of people canceled. So we slid right in not minding the weather at all, it made for a great photographs. The campsites are very close together, but it’s a small price to pay to sleep on the valley floor. It allows you to wake up super early and beat the huge crowds to have Yosemite to yourself.
