Instead of Denali National Park: Cape Krusenstern National Monument, Alaska
Situated north of the Arctic Circle along 70 miles of the Chukchi Sea’s shoreline, the only way to reach Cape Krusenstern is by authorized air taxi or charter boat. This remote wilderness area is open all year round for backpacking, boating, camping, and flightseeing, but the rugged terrain is less challenging to navigate without snow in summer. But with no roads, trails, or designated campgrounds, the park service recommends hiring an authorized guide and ensuring that you are ready to handle the challenges of backcountry camping in the Arctic for the safest stay. (Visitors should have a way to communicate as there is no cell service in the park in addition to knowledge of camping skills, bear and muskox safety, how to stay warm and dry, and how to protect against mosquitos.) During your trip, stop by the Northwest Arctic Heritage Center for programming, such as the Arctic Circle Film Series on Wednesday nights.
Instead of Haleakalā National Park: Papahānaumokuākea Marine National Monument, Hawaii
Encircling more than 580,000 square miles of the Pacific Ocean, Papahānaumokuākea Marine is larger than all U.S. national parks combined. While it’s not currently open for historic and eco tours due to staff reductions, visitors can experience it from afar at four learning centers across the country: The Mokupāpapa Discovery Center in Hilo, Waikīkī Aquarium and Bishop Museum in Honolulu, and Nantucket Whaling Museum in Massachusetts. Notable features include coral reefs and lagoons, seamounts and submerged banks, and archeological remains from pre-European settlement. In addition to protecting fragile marine ecosystems, the monument commemorates the kinship of two Hawaiian ancestors—the Papahānaumoku and the Wākea.
