The national parks are a treasure—beautiful, wild, and full of wonders to see. But there’s more to experience than taking in gorgeous scenery from your vehicle or lookout points. National parks are natural playgrounds, full of possible adventures.
The most famous offerings of the National Park Service (NPS) are the 63 national parks including Arches, Great Smoky Mountains, and Grand Canyon. But there are 424 NPS units across the country that also includes national monuments, national seashores, national recreation areas, national battlefields, and national memorials. These sites are outside the main focus of this guide.
The list of national parks to visit in July is wonderfully diverse. Visit Carlsbad Caverns, go hiking in Lassen Volcanic, spend some time in the tranquil forests in Sequoia and King Canyons National Parks, and explore one of the most underrated US national parks, Theodore Roosevelt.
In this guide, I cover five great parks to visit plus four bonus parks.
About this National Park series
This article is part of a series about the best national parks to visit each month. In this series, every national park is listed at least once and many are listed multiple times. It is a series of 12 articles, one for each month of the year.
These articles take into account weather, crowd levels, the best time to go hiking, special events, road closures, and my personal experiences in the parks. Based on these factors, I picked out what I think are the optimal times to visit each park. Since I haven’t been to all of the national parks I include only the parks we have visited on at lease one occasion.
For an overview of the best time to visit each national park, check out my Best National Parks by Season guide. This guide will cover the best time to visit each national park based on these factors. First are the links to my posts about the best parks to visit, month-by-month. This is followed by a list that illustrates the best time to visit each national park based on weather and crowd levels. Please note this overview will be posted following the completion of this 12 month guide in February 2024.
And at the end of this article, I have links to the other guides in my Best National Parks by Month series.
Visiting the National Parks in July
July is the busiest month of the year to visit the national parks. The weather is warm, the days are long, and many people are hitting the road for summer vacation.
By July, all of the national parks are fully open with the last high mountain roads opening by early July. So, you can pretty much visit any park you want. However, some parks are very hot this time of year (particularly across the south and into the American Southwest) and some are extremely crowded (Yellowstone, Rocky Mountain, and Great Smoky Mountains make this list). You won’t see these parks on my list for July but there are some parks with lower crowds and great weather that make excellent picks this month.
IMPORTANT NOTE: The information I provide for each national park does not include temporary road closures, since these dates are constantly changing. Roads can close in the national parks at any time, so I recommend getting updates on the NPS website while planning your trip.
Best National Parks in July
1. Lassen Volcanic National Park
This national park protects Lassen Peak, the largest plug dome volcano in the world. In Lassen Volcanic you’ll see steaming fumaroles, pretty lakes, colorful landscapes, and Lassen Peak.
Snow lingers on the roads and trails at the higher elevation of the park into June and sometimes into early July. If you want to hike to Lassen Peak and have full access to the park, July is the earliest time of the year when this is possible.
Cool fact: Lassen Volcanic National Park one of the only places in the world where you can see all four types of volcanoes: shield, stratovolcano, cinder cone, and plug.
Why visit Lassen Volcanic in July: By early July, the roads and trails in the higher elevations of the park open, so this is about the earliest you can visit Lassen Volcanic and have full access to the park. Plus, the weather is pretty much perfect this time of year.
Weather: In July, the average high is 72°F and the average low is 40°F. Rainfall is low.
Sunrise & sunset: Sunrise is at 5:30 am and sunset is at 8:40 pm.
Top experiences: Walk Bumpass Hell Trail (isn’t that the best name for a hiking trail?), capture the reflection of Lassen Peak in Manzanita Lake, go for a scenic drive on Lassen Park Highway, visit Kings Creek Falls and Mill Creek Falls, visit Devils Kitchen, and hike to the top of Lassen Peak.
Ultimate adventure: Hike to the summit of Brokeoff Mountain for panoramic views of the park. Note, this hike is best attempted in late summer to early fall when the trail is free of snow.
How many days do you need? One day is just enough time to see the highlights but plan on spending two to three days here to hike several more trails and thoroughly explore the park.

2 & 3. Sequoia & Kings Canyon National Parks
Sequoia and Kings Canyon National Parks sit side by side in central California. Filled with alpine peaks, deep canyons, and the largest trees in the world, you should spend several days here.
Kings Canyon preserves a glacially carved valley (named Kings Canyon) and Grant Grove which is home to General Grant, the second largest tree in the world.
Sitting right beside Kings Canyon is Sequoia National Park. It is here that you will walk among towering sequoia trees and see the largest tree in the world, the General Sherman.
Why visit Kings Canyon & Sequoia in July: July is the busiest month of the year to visit but the weather is great.
Weather: The average high is 83°F and the average low is 65°F. Rainfall is very low.
Sunrise & sunset: Sunrise is 5:40 am and sunset is 8:05 pm.
Top experiences: Visit Grant Grove and drive Kings Canyon Scenic Byway, visit Zumwalt Meadows, see the General Sherman Tree, hike Moro Rock, and visit Crescent Meadows.

4. Theodore Roosevelt National Park
Location: North Dakota
Theodore Roosevelt National Park is a picturesque wilderness of grasslands and badlands. Bison, feral horses, pronghorns, and elk roam the landscapes, hiking trails meander through the colorful bentonite hills, and scenic roads take visitors to numerous stunning overlooks.
This national park is made up of three separate units: the South Unit, the North Unit, and the Elkhorn Ranch Unit. Of the three, the South Unit is the more popular. In the North Unit, the views of the badlands are beautiful, there are several short, fun trails to hike, and there is a very good chance you will spot bison and other wildlife right from your car.
Why visit Theodore Roosevelt in July: For those seeking out a little solitude in nature, the somewhat out of the way location of Theodore Roosevelt National Park can be a blessing in disguise. While many national parks are battling traffic congestion and parking problems during the peak summer season, you may see more bison than people during your time at this amazing national park. While summer is the busiest time at the park, though by national park standards, it’s still not very busy.
Weather: Summer also brings the warmest weather with high temperatures averaging in the 80s, and sometimes into the 90s. Rainfall is relatively low with about 2 inches of rain falling in July.
Sunrise & sunset (South Unit): Sunrise is at 5 am and sunset is at 8:50 pm. The South Unit is in the Mountain Time Zone and the North Unit is in the Central Time Zone.
Top experiences: Hike the Caprock Coulee Trail, enjoy the view from Sperati Point and the Wind Canyon Trail, drive the Scenic Drive in both units, visit the Petrified Forest, hike the Ekblom and Big Plateau Loop, and visit River Bend Overlook.
How many days do you need? If you want to explore both the North and South Units, you will need at least two days in Theodore Roosevelt National Park (one day for each unit).

5. Carlsbad Caverns National Park
Location: New Mexico
An underground fantasy land of limestone chambers, stalactites and stalagmites, and long, twisting tunnels is located in the Guadalupe Mountains of New Mexico.
From late May through October you can watch the Bat Flight program. At the Bat Flight Amphitheater, grab a seat and watch as the bats emerge by the thousands from the natural entrance of the cave. The best time to see the bats is in August and September when the baby bats join the show. The Bat Flight Program takes place every evening and it is weather dependent.
Why visit Carlsbad Caverns in July: To watch the Bat Flight Program when bats emerge by the thousands from the natural entrance of the cave.
Weather: In July, the average high is 91°F and the average low is 67°F. July is one of the wettest months of the year with 2 inches of rainfall. The average temperature throughout the cave is 68°F and the relative humidity remains close to a constant 100 percent.
Sunrise & sunset: Sunrise is at 6:20 am and sunset is at 7:40 pm.
Top experiences: Tour the caverns on your own or on a ranger-guided tour. You can also go star gazing, hike a surface trail, or go on a scenic drive.
How much time do you need? A half to a full day is all you need to explore the caverns on your own and/or take a ranger-guided tour.

Bonus! 4 NPS sites to visit in July
National park-like amenities tell the story of America’s most infamous active volcano. Gorgeous wildflower-packed views of the volcano can be enjoyed in spots like Bear Meadows while those seeking a closer view of the crater rim may drive to the Windy Ridge viewpoint or even summit the rim of the 8,365-foot volcano with a permit.
Cumberland Island National Seashore includes one of the largest undeveloped barrier islands in the world. The park is home to a herd of feral, free-ranging horses. Most visitors come to Cumberland for the natural glories, serenity, and fascinating history. Built by the Carnegies, the ruins of the opulent 59-room, Queen Anne-style Dungeness are a must-see for visitors.
At first glance, you could be forgiven for thinking this is Bryce Canyon National Park. It looks almost identical to its more famous national park cousin which is located about an hour to the east. Yet with less than a quarter of the annual visitation of Bryce, this small but mighty national monument makes a worthy alternative for those seeking color-packed canyon views stretching across three miles at an elevation of around 10,000 feet.
Encompassing over 1.25 million acres, Glen Canyon National Recreation Area stretches for hundreds of miles from Lees Ferry in Arizona to the Orange Cliffs of southern Utah. Outdoor activities are what Glen Canyon is all about. There is something for everyone’s taste.

Earth and sky, woods and fields, lakes and rivers, the mountain and the sea, are excellent schoolmasters and teach some of us more than we can ever learn from books.
