10 Most Underrated National Parks in the USA


#10 — Wind Cave National Park (South Dakota)

  • Annual visitors: Under 600,000
  • Often overshadowed by neighboring Badlands National Park

Highlights:

  • One of the longest cave systems in the world
  • Rare boxwork formations found nowhere else
  • Above ground: large roaming bison herds

Best time to visit: Late spring through early fall Recommended duration: 1 full day (creators did 2 different day tours)


#9 — Pinnacles National Park (California)

  • Annual visitors: Under 350,000

Highlights:

  • Cave hikes (when open)
  • One of the only places to get a close view of endangered California condors
  • Striking rock formations
  • Variety: lakes, caves, peak hikes, and strong wildlife sightings

Best time to visit: Spring (April–May) or fall (October–November) — summer gets very hot Recommended duration: Full day (sunrise to sunset)


#8 — Carlsbad Caverns National Park (New Mexico)

  • Annual visitors: ~400,000
  • Small park, easily paired with nearby White Sands National Park

Highlights:

  • One of the largest cave chambers on Earth — described as "mind blowing"
  • Some of the best stalactite/stalagmite formations in the world
  • Bat flight at sunset — bats exit the cave en masse (skip if you dislike bats)

Best time to visit: October–April (cooler desert temps) Recommended duration: 1–2 days (1 day if combining with White Sands)


#7 — Lassen Volcanic National Park (California)

  • Annual visitors: ~500,000
  • Often overlooked due to proximity to Yosemite and Redwoods

Highlights:

  • Described as a "mini Yellowstone" — significant geothermal activity
  • Boiling mud pots
  • Cinder cone volcano hike
  • Scenic lakes
  • One of the most beautiful drives in California

Best time to visit: July–October (avoids snow/slippery slopes); winter visits possible with snowshoes/yak tracks, though much of the park closes Recommended duration: 2–3 days


#6 — Kings Canyon National Park (California)

  • Annual visitors: Under 600,000
  • Located less than 1 mile from Sequoia National Park

Highlights:

  • Feels like "a little Yosemite" — massive granite domes
  • Roadside waterfalls
  • Meadows for exploring
  • Backpacking with close bear sightings

Best time to visit: Late spring through early fall (summer = most beautiful meadows, but can get extremely hot) Recommended duration: 1–2 days for highlights/drive-throughs; 2–3 days for hiking


#5 — Canyonlands National Park (Utah)

  • Annual visitors: ~800,000 (about half of neighboring Arches National Park)

Highlights:

  • Some of the best photography opportunities in the world
  • Designated Dark Sky Park — excellent for stargazing/astrophotography
  • Quiet, peaceful, remote camping
  • Extensive backpacking routes across multiple park sections
  • Schaefer Trail — off-roading route through the canyons back to Moab (or take a Pink Jeep tour if you don't have an off-road vehicle)

Best time to visit: Spring or fall (shoulder seasons) — September visit was ~90°F and uncomfortable for hiking Recommended duration: 1–2 days for hiking; longer for backpacking


#4 — Capitol Reef National Park (Utah)

  • Annual visitors: 1.3 million (still far less than neighboring Zion National Park)
  • Part of Utah's "Big Five" national parks but the least visited

Highlights:

  • Scenic drives
  • Off-roading opportunities
  • Hidden arches for hiking/exploring
  • Working orchards inside the park where visitors can pick fruit

Best time to visit: Spring or fall (winter is extremely cold, summer is extremely hot)


#3 — Channel Islands National Park (California)

  • Annual visitors: ~300,000
  • Located in Ventura County — a local favorite for the creators

Why it's underrated: Requires more planning — ferry access, campsite reservations, ferry availability, and packing in your own water for overnight island stays

Recommended islands:

  • Santa Cruz Island (top recommendation for first-timers): sea cave kayaking tours, strong hiking trails, Channel Islands foxes, abundant bird life
  • Anacapa Island: 1 day is sufficient (creators have a separate multi-day camping video on this island)

Activities: Paddleboarding, snorkeling (wetsuit recommended — water is chilly), kelp forest viewing

Best time to visit: Late spring to early fall — avoid seagull breeding season (approximately April–May; verify exact dates)


#2 — Glacier Bay National Park (Alaska)

  • Annual visitors: ~700,000 (mostly via cruise ships — difficult to access otherwise)

Highlights:

  • Massive glaciers with frequent calving — described as more impressive than glacier viewing in Antarctica or Svalbard
  • Significant wildlife presence

Best time to visit: June–August (peak cruise season) Recommended duration: 1–2 days (cruise passengers typically get only 1 day; an expedition ship allows for a longer visit — recommended if possible)


#1 — North Cascades National Park (Washington)

  • Annual visitors: ~30,000 — by far the lowest on this list
  • Likely underrated due to difficult access from Seattle/Vancouver (a passport may be needed if routing through Canada)
  • Dramatically less visited compared to nearby Mount Rainier National Park

Highlights:

  • Alpine lakes with extremely turquoise water
  • Glacier-covered peaks — compared to the Swiss Alps
  • Remote, rugged backcountry backpacking

Best time to visit: July–October (note: late season, especially September–October, often brings wildfires — monitor conditions) Recommended duration: 2–3 days minimum; creators suggest 4–5 days for a more relaxed pace, since most notable hikes are 3–10 miles each (one major hike per day rather than stacking multiple hikes)
