Summer has officially arrived, and so has one of the best months to get outside and explore America’s national parks. June is a sweet spot — wildflowers are blooming, waterfalls are roaring, wildlife is active, and many high-country roads and trails are finally accessible. Whether you're a hiker, road tripper, or casual explorer, these five parks shine especially bright this time of year.
Here are 5 National Parks to Visit in June — plus insider tips to make the most of your trip!
1. Glacier National Park, Montana
Why June Rocks:
While July is peak season, June is Glacier’s secret season. Going-to-the-Sun Road usually opens late in the month (check status before you go), and snow still lingers at high elevations, making for surreal alpine views. You’ll find fewer crowds, lots of waterfalls from snowmelt, and wildlife like mountain goats and grizzlies out and about.
Don’t Miss:
- Avalanche Lake hike through a forest of cedars
- Sunrise at Lake McDonald
- Exploring Two Medicine for a quieter alternative to the main west entrance
Pro Tip: Pack layers! Snow is still possible at Logan Pass, even in late June. Bear spray is a must.
2. Great Basin National Park, Nevada
Why June Rocks:
One of the most underrated parks in the West, Great Basin shines in June. Temps are warm but not scorching, the Bristlecone Pines are accessible, and the stargazing is out of this world (literally — it’s an International Dark Sky Park).
Don’t Miss:
- A ranger-led tour of Lehman Caves
- The hike to the ancient Bristlecone Pine Grove
- A drive up Wheeler Peak Scenic Drive
Pro Tip: Go during the new moon for the best stargazing. The night sky here is jaw-dropping in June.
3. Acadia National Park, Maine
Why June Rocks:
Before the July crowds roll in, June is ideal for exploring Acadia’s dramatic coastline and lush forests. Lupines and wildflowers are blooming, puffins are nesting offshore, and the sea air is just right.
Don’t Miss:
- Sunrise on Cadillac Mountain
- The Jordan Pond House popovers & tea tradition
- Biking the Carriage Roads
Pro Tip: Make a vehicle reservation early if you plan to drive up Cadillac Mountain. And bring a light jacket — coastal Maine can still be breezy and cool in June.
4. North Cascades National Park, Washington
Why June Rocks:
It’s called the “American Alps” for a reason. June brings rushing waterfalls, emerald lakes, and alpine meadows waking up from winter. Snow still caps the rugged peaks, but lower elevation trails are clear.
Don’t Miss:
- Diablo Lake Overlook — unbelievably turquoise
- Hikes around Rainy Pass
- Camping under the stars near Colonial Creek
Pro Tip: Prepare for rapidly changing weather. It’s remote out here — be self-sufficient with food, water, and layers.
5. Sequoia & Kings Canyon National Parks, California
Why June Rocks:
By June, the snow has receded from the Giant Forest and Cedar Grove areas, opening up some of the most dramatic landscapes in the Sierra Nevada. Waterfalls are still flowing strong, and crowds haven’t hit their summer peak.
Don’t Miss:
- General Sherman Tree and Congress Trail
- Driving down to Zumwalt Meadow in Kings Canyon
- Hiking Moro Rock for panoramic views of the Great Western Divide
Pro Tip: Altitude makes a difference! Most sights are over 6,000 feet. Take it easy your first day and stay hydrated.
Final Tips for June Park Adventures:
- Check conditions before heading out: Snow, road closures, and wildlife can all affect June plans.
- Book campsites and lodges early, especially in popular parks.
- Pack layers — June can bring 80s in the valleys and snow in the mountains!
- Leave No Trace and help protect these beautiful places for the next adventurers.
