Tips for Avoiding Crowds at National Parks
The best tip for avoiding crowds at national parks is to avoid national parks altogether. The United States has over 640 million acres of public lands to explore, which include national forests, state parks, and much more.
However, if those national parks are on your bucket list and you can’t miss out, here are a few tips for helping you experience some solitude while you’re there.
Visit during off-peak seasons:
Most national parks experience a surge in visitors during popular vacation times, such as summer and holidays. Plan your trip during the shoulder seasons, like spring and fall, when crowds are generally thinner, and you can enjoy a more peaceful experience.
Arrive early or stay late:
Many visitors tend to arrive at national parks during the late morning and afternoon. To avoid crowds, aim to arrive early in the morning or plan to stay until late afternoon or evening.
Not only will you encounter fewer people, but you’ll also have better opportunities for wildlife sightings and enjoy spectacular sunrises or sunsets.
Explore lesser-known trails and attractions:
National parks often have popular trails and viewpoints that draw the majority of visitors. Do some research and find lesser-known trails or areas within the park that are off the beaten path. These locations will typically be less crowded and offer unique perspectives of the park.
Utilize park shuttles and public transportation:
Many national parks offer shuttle services or public transportation options to help manage traffic and reduce congestion. Utilizing these services can help you avoid the stress of finding parking, and you may discover new areas of the park that are less crowded.
Be flexible with your itinerary:
Having a flexible itinerary can help you avoid crowds by adjusting your plans based on real-time conditions. If a particular area or trail is crowded, be prepared to explore an alternative location within the park.
Keep an eye on the park’s social media accounts or website for updates on crowd levels, and use that information to plan your day accordingly.
My Top 2 National Park Picks for Little to No Crowds
My top choices out of this list of the least-visited national parks in the Lower 48 would have to be North Cascades National Park for its stunning views and world-class hiking.
Growing up by Glacier National Park, I love mountain vistas and North Cascades National Park offers a similar backdrop without hordes of people.
My second choice would be White Sands for an entirely different reason. While there are hiking trails, the main reason to visit is for the unique landscape–the only one like it in the world. If you want a truly one-of-a-kind park, this is the place.
