Before we get into it, we want to remind everyone to explore the parks responsibly using the 7 Leave No Trace Principles. Have a plan, stay on established trails, carry out anything you carry in, leave what you find, minimize campfire impact, respect wildlife, and be considerate of others.
About the National Park by Month Series
To put together this list, we’ve combined our personal experiences and tips we gathered from locals and cross-referenced them with the weather, accessibility, local forums, seasonal attractions like fall foliage or wildflowers, and special events happening in the area. We also considered any unique adventures only offered at certain times of the year to find the most optimal months to visit each National Park. Phew! That was a lot!
It took me a whole week of research, but since I’m a maximizer, it was completely worth having a year-round calendar of adventures (publishing that soon!). Also, check out our complete list of all the national parks and all national park units that include soon-to-be national parks.
We also chose not to include the hardest-to-access national parks in Alaska and the ones in U.S. territories in this series.
National Parks By Month: Jan | Feb | Mar | Apr | May | Jun | Jul | Aug | Sep | Oct | Nov | Dec
Is May a Good Time to Visit National Parks?
May is a great time to visit National Parks for a few reasons. The weather is generally mild in most regions making it great for outdoor activities. It also marks the beginning of Spring in many parks so the flowers are blooming. For wildlife, animals begin emerging from winter hibernation or start preparing for mating season so they are active. Lastly, the crowds are typically smaller than summer crowds.
Plan on visiting more than two national parks this year? Pick up an America the Beautiful annual pass to save money (entrance fees to each park are, on average, $30-35 per vehicle). Plus, you are helping support the Parks that always need funding.

Tips for Visiting National Parks in May
Use the Leave No Trace principles. Have a plan, stay on established trails, carry out anything you carry in, leave what you find, minimize campfire impact, respect wildlife, and be considerate of others.
Pick up the National Park Annual Pass if you plan on visiting multiple parks within the year. It saves you a lot of money.
Want to see spring blooms? Climate change and droughts can make timing unpredictable. We typically scroll through Instagram or TikTok and look for non-influencers.
Packing layers is always a good idea when traveling. Some parks drastically change temperatures from day to night. Pay attention to the elevation change. A general rule is that it’s 5 degrees cooler for every 1000 ft elevation.
You may need a reservation. See national parks that now require reservations here.
Closures – Always check the park’s site and Visitors Center for the most up-to-date information on closures.
Remember that wildlife is wild. Be familiar with how to interact with animals and how much space you should have between you and them. Generally, you should stay 25 yards from most wildlife and 100 yards from predators, but each park has different rules.
What to Pack
How you pack depends on the parks and activities, but here are general items we always pack.
Camping / Backpacking Equipment
Layers (The Best Travel Jackets)
Planning Checklist
Download these helpful language apps.
Arrange a rental car for your trip.
Get a new backpack for your trip.
Pack the appropriate shoes for your trip.
Don’t forget your in-flight essentials.
