The best time to take a US National Parks tour is generally during shoulder season, either spring (April to May) or fall (September to October), with fewer crowds and mild weather. However, summer is often best for watching wildlife, while winter is good for desert parks like Grand Canyon or Death Valley.

June is considered the best time to visit Yellowstone National Park; with abundant wildlife sightings, pleasant weather and lighter crowds ahead of the busy summer peak, it's one of the best months for US National Park vacations.

The best thing to do in Grand Canyon National Park is get outside, whether that's watching sunrise over North Rim, taking in the vistas at Desert View Point, meeting a local geologist to understand the 5-million-year-old rock formations, or taking to the sky for a flightseeing tour.
