I've been to all 63 major US national parks. Here are the 3 I love going back to and the 3 I'm glad I saw once.

Acadia National Park is known for its fall foliage, great hiking trails, and being the first location to see the sunrise in the Continental United States from October 7 to March 6.

Although all of these things play a part in why I continually go back to Acadia, what I love the most is the park's rugged coastline and proximity to Bar Harbor.

Drive, walk, bus, or bike just 1.3 miles from the quaint town of Bar Harbor, and you're in one of the country's most scenic national parks.

The park's modest size is also a blessing in disguise. You can either quickly see the highlights or spend a longer time at each stop without feeling rushed or overwhelmed, which, for me, has created a stronger connection to the park.

Grand Teton National Park in Wyoming was one of the first I visited solo. From the second the Teton Range came into view in my windshield, I knew it would be the place I would return to more than any other.

From challenging hikes to unique, jutting mountain peaks and crystal-blue alpine lakes, there is always something new to discover at this park.

Grand Teton is close to Jackson, Wyoming, and is the only national park with a commercial airport entirely within its boundaries. I love that the park feels remote but is relatively easy to visit.

West Virginia's New River Gorge was named the 63rd US national park in 2021. Although its status only changed a few years ago, I've already visited several times and plan to return.

This park is easily accessible and has activities and beauty to impress even the most well-traveled park visitor.

I recommend spending the day hiking, driving, or even white-water rafting in this stunning and unique part of the country.

Alaska's Gates of the Arctic National Park is an incredible sight to see. Encompassing over 8.4 million acres of land entirely north of the Arctic Circle, the second largest US national park is also the least visited — with just 11,045 visitors making the trek last year.

Getting there is part of the adventure, as there are no roads or established trails to enter the park. Because of this, though, I had to book a series of three flights to get there — the last of which cost $1,750 roundtrip.

Although it was definitely worth seeing the incredible landscapes of the Brooks Range, due to the logistics and cost, I likely won't be visiting more than once.

One of the last parks I visited was also one I was most excited about: Katmai National Park in Alaska.

Although I loved my time hiking and observing the large population of brown bears, I likely won't return due to cost and logistics.

Similar to other parks in Alaska, no roads connect it to other parts of the state, so visitors must fly or boat in. I flew to King Salmon, Alaska, on a charter plane and then to Brooks Falls on a seaplane for a total of $1,350.

Another reason I'm glad I visited just once is because it truly is a wilderness park, with much of it being backcountry and less than 6 miles of maintained trails. At the end of the day, I'm not comfortable exploring Bear Country alone as a solo traveler.

The National Park of American Samoa is extraordinary and unique, not just as a national park but also simply as a destination.

The park, which is the only NPS site south of the equator, will forever be one of my favorite unique national park trips. Although I'd love to return, it's unlikely I will due to logistics. After all, the park is one of the most remote in the US.

Only two flights make the nearly six-hour journey from Honolulu to Pago Pago, American Samoa, each week — and each roundtrip flight costs at least $1,000.

Planning is also a little complex from there, as there is little tourism infrastructure. However, there's something very special to me about having what can accurately be described as a once-in-a-lifetime trip.
