When the earliest visitors of the first national parks wanted to plan a visit, they would have consulted maps, read texts, or, even better, talked to the select few others who had made their own pilgrimage to parks like Yellowstone, Yosemite, or Zion National Park.

Now that the internet has made researching a park and planning a trip incredibly easy, it’s tough to imagine having only a map and a few first-hand accounts to go by.

However, the internet hasn’t made us any less eager to hear what others who have visited a national park have to say about it. Review sites like Yelp and TripAdvisor allow visitors to leave behind a few words or even a few paragraphs about their own experience to help others plan theirs. These sites are packed with great reviews of our nation’s most beautiful public lands. But not all guests share those great experiences.

Keep reading to see some of the worst–and funniest–reviews of national parks left by disgruntled, confused, or tough-to-please travelers.

Review of Arches National Park:

“Delicate Arch looks like it might fall over at any time. it might fall over in the future. Doesn’t look anything like the license plate.”

Review of Glacier National Park:

“At the time of our visit, half of the road was closed due to snow! Well, there was no snow on the mountains and it being late June, it could not possibly have snowed there! Was there a UFO landing? Pretty fishy.”

Review of Mammoth Cave National Park:

“The worst national Park I’ve ever been to,” he wrote. “My buddy really want to try the restaurant here and figures it’s close [sic] for renovations so we had to go to the campground little café thing to get some food and they charge four dollars for microwaved burger. That’s were pretty much started on a bad experience.”

Review of Canyonlands National Park:

“If you have seen the Grand Canyon, it is not clear why you would need to make the three hour round trip drive from hwy 191 and back to see Canyonlands. This park is similar but 10 times wider and flatter.”

Review of Joshua Tree National Park:

“Problem: WE HARDLY SAW ANY JOSHUA TREES! Yes…while in the park. In fact, we only began to see loads of joshua trees outside the park as we drove through Joshua Tree, CA.” 

Review of Hawaii Volcanoes National Park:

“Paid $20 to get in. Didn’t even get to touch lava. The trails are cool though. Except that 10 mile hike to a steam vent. Forget that.”

Review of Bryce Canyon National Park:  

“I never got to see anything, as the road within the park is not at all revealing to the presence of anything but trees. As a result, I opted not to drive any farther in the direction of a National Park. We skipped Zion and the Grand Canyon because this was the worst experience I’ve ever had in a park, the grand finale of bad experiences in a week of trying to tour the ones in Utah.”

Review of Grand Canyon National Park:

“The reason I give Grand Canyon National Park only one star as a National Park is that pretty much all of the really awesome things you could potentially do in the Grand Canyon are basically off-limits for a day tripper…I just don’t understand why they won’t build a road, aerial tramway, elevator, or SOMETHING that gives easier access to the canyon’s depths. To people who say that building anything would ruin the Grand Canyon, I would say this – did building a road into Yosemite Valley ruin Yosemite?”

Review of Yosemite National Park:

“Trees block views and too many grey rocks.”

Review of Capitol Reef National Park:

“There are almost nothing fun in the park. An elementary school closed in 1940s can be labeled as a place of interest? Couple small paintings on rock are considered as an attraction? The creek is completely dried up, and a few extremely boring trails that can only be accessed by driving through 10+ miles of unpaved road. BTW, the roads are so narrow that you need to drive with great caution to avoid hitting other cars.”

Review of Badlands National Park:

“I didn’t see what the big deal was. We drove a million years to see some semi impressive rock formations? And there were RATTLESNAKES everywhere? Dumb. You lose cell service because you’re in Nowhere USA. The only thing bad about these lands is the entire experience. Waste of time.”

Review of Yellowstone National Park:

“It’s like a bigger version of Central Park, only with bears.”

Review of Sequoia National Park:

“This place is dangerous. There are bears, mountain lions and worst of all, sketchy people. Hide your wives, hide your kids, hide your husbands, because they will come they [sic] your window. There are bugs and stuff, and they will bite you on your face. Don’t waste your time here. Go to Vegas, for sure Vegas is practical, and has 7-Elevens.”
