Yellowstone is busier than ever - but these lesser-known national park sites offer similar views, according to someone who's visited all 423 of them

• Yellowstone National Park has experienced record-breaking visitor numbers so far this summer.
• Mikah Meyer, who's visited all 423 National Park Service sites, suggested less-crowded alternatives.
• Instead of Yellowstone, Meyer recommended Craters of the Moon or Lassen Volcanic National Park.

This summer, $4 comparable to theme parks like Disneyland. Some popular sites, like Arches National Park in Grand County, Utah, have closed their gates due to crowding more than 80 times so far this year, the $4 reported in June.

Another popular park, Yellowstone, which sprawls across parts of three states - Wyoming, Montana, and Idaho - has seen more visitors than ever since reopening all entrances in 2021, $4.

Meyer recommended visiting Craters of the Moon National Monument and Preserve, a lesser-known site in Idaho that is a three-hour drive from Yellowstone. He said Craters of the Moon is just as other-worldly as Yellowstone.

"It sort of feels like you're on the moon," Meyer said of visiting the national monument and preserve.

Craters of the Moon is filled with lava flows, $4, making it especially scenic.

The park also has lava caves that are open for exploring, according to the National Park Service.

Instead, Meyer told Insider that people can visit California's Lassen Volcanic National Park for a less-crowded view of bubbly, steaming natural wonders. Located about 13 hours west of Yellowstone by car, this park has eight hydrothermal areas, from geysers to boiling springs, $4.

Hot water and past eruptions have shaped the land filled with volcanoes, lakes, meadows, and bubbly mud spots where steam and sulfur rise from, according to the National Park Service.
