About Yellowstone National Park in May
Yellowstone is an absolutely spectacular and magical national park. A landscape dotted with otherworldly thermal works, bison holdouts from a time when they ruled the prairie, a thriving wolf population, and an encapsulation of the great American west.
The temperatures in Yellowstone in May are actually somewhat chilly with highs in the low 50s. The tradeoff is simple – the crowds. May is still a great time to visit Yellowstone because the impossible crowds of summer have not yet materialized. Beyond that, things are starting to come to life again, with new bison calves, and spring leaves.

About Grand Canyon National Park in May
In the words of Theodor Roosevelt:
“In the Grand Canyon, Arizona has a natural wonder which is in kind absolutely exceptional throughout the rest of the world. I want to ask you to keep this great wonder of nature as it now is.
I hope you will not have a building of any kind, not a summer cottage, a hotel or anything else, to mar the wonderful grandeur, the sublimity, the great loneliness and beauty of the canyon.
Leave it as it is. You cannot improve on it. The ages have been at work on it, and man can only mar it.“

Crater Lake National Park
In May Crater Lake is *just* starting to melt and in between the beautiful winter and summer seasons. The main park road is still closed as are the campgrounds and the main lodge until the end of the month. For these reasons we recommend holding off visiting until at least June.

Mount Rainier is one of the most beautiful national parks in the world but May is just not the best time to visit. Most of the trails are still snowed in and several roads are still closed. Wildflowers don’t start showing up until the July. Snow is just starting to melt at lower elevations making traversing the park difficult. We recommend holding off until June at the earliest.
