August
Glacier National Park, Montana
August is the best time to visit Glacier National Park because the iconic Going-to-the-Sun Road is guaranteed to be fully open by then, allowing you to drive across the entire park.

Yellowstone National Park, Wyoming/Montana
Yellowstone National Park may be one of the most recognizable parks in the United States, with scenic vistas, unique geology, and wildlife.

Olympic National Park, Washington
Visiting Olympic National Park in August will give you the lowest chance of rainfall throughout the year and full trail accessibility, allowing you to see both sides of this diverse park: a temperate rainforest and alpine peaks. Since the park features wildly contrasting climates—ranging from a temperate rainforest that receives up to 140 inches of annual rain to glaciated mountain peaks—August serves as the ultimate weather window. High-elevation snowpack has completely melted, revealing hidden alpine trails, and the famously wet rainforest floors have dried out enough for comfortable day hikes. Daytime temperatures remain incredibly pleasant, averaging in the upper 60s to mid-70s (°F)
September
Grand Teton National Park, Wyoming
As the calendar turns past Labor Day, family vacation traffic drops significantly, leaving the Grand Teton National Park peaceful and highly accessible.

Grand Canyon National Park, Arizona
September is a prime month to visit Grand Canyon National Park due to the drop in temperatures and crowds. Daytime temperatures on the South Rim drop to an incredibly comfortable average of 77°F, while the inner canyon cools down significantly from its dangerous summer extremes, making it the premier month for hiking and enjoying the scenic view. The park has something for everyone, with several pull-outs, educational signs, and short walks, as well as rim-to-rim backcountry trails.
Badlands National Park, South Dakota

October
Acadia National Park, Maine
Yosemite National Park, California
Yosemite is one of the most popular national parks in the United States, and as such, many visitors like to visit after the peak summer months have passed. October offers pleasant temperatures in the low 70s (F), and crisp nighttime temperatures in the 40s (F). While most of the park consists of evergreens, during October, clusters of deciduous trees pop with fall colors. Early to late October offers the last chance to drive the scenic Tioga Road and Glacier Point Road. Don’t miss the Yosemite Valley Loop Trail or drive one of the many scenic drives in the park.
November
Saguaro National Park, Arizona
While summertime brings oppressive, triple-digit heat to Saguaro National Park, November brings perfect desert weather. This park’s busy season is typically November – March, so plan your visit in early November to beat the crowds. Explore the two distinct areas of the park: the dense cactus forests in the Tucson Mountain District (West), and the rugged, soaring mountain terrain of the Rincon Mountain District (East). Hike to the Signal Hill Petroglyphs on a short, scenic walk through the giant saguaros to look at hundreds of ancient rock carvings etched into stone by the Hohokam people over 800 years ago. Or, enjoy the Bajada Loop and Cactus Forest Drive, both of the park’s scenic loop roads.
White Sands National Park, New Mexico
The unique gypsum sand at White Sands National Park reflects the sun, rather than absorbing it like regular sand, making summer months especially hot and creating a blinding scene. November brings relief, delivering perfectly crisp, sunny autumn days with average highs of 66°F, making all-day exploration and sand sledding extremely comfortable. Those looking to explore on foot should check out the Alkali Flat Trail. Another reason that November is the best time to visit White Sands National Park is that it marks the launch of the park’s limited-capacity Lake Lucero Tours, a unique seasonal opportunity where park rangers guide visitors out to the massive, ancient dry lakebed to see the giant selenite crystals that form the source of the white sand.
December
Biscayne National Park, Florida
95% of Biscayne National Park is water, so it’s important to have great weather for your adventure. December marks the beginning of the dry season in Florida, creating perfect conditions for boating, kayaking, and snorkeling. With average daytime highs sitting at a perfect 76°F and lots of sunshine, it provides the ultimate subtropical winter. December is also the best month to spot West Indian manatees, as they migrate from the cooling inland freshwater to warmer, shallow saltwater bays, where they feed in seagrass beds near the mainland shoreline, such as in Biscayne Bay.
Everglades National Park, Florida
As with Biscayne NP, December at Everglades National Park is the beginning of the dry season, bringing comfortable temperatures, fewer mosquitoes, and unmatched wildlife visibility. As the vast sawgrass marshes begin to dry out, fish, turtles, and wading birds are forced into localized deep-water pools. This draw of prey coaxes hundreds of giant American alligators and crocodiles out to sun themselves directly alongside the park’s main trails and boardwalks. In addition, December is the prime month for birdwatching, as it marks the arrival of thousands of stunning migratory birds. Visitors can easily spot iconic species like roseate spoonbills, wood storks, anhingas, and great blue herons hunting in the shallow pools.
