Make sure to wear comfy shoes! The walking paths are pretty easy, but you’ll still be on your feet a lot, and no one wants sore feet after exploring.

Don't skip the gift shop on your way out. They got some unique souvenirs you won’t find anywhere else, and it’s nice to grab a little something to remember the trip.

I suggest buying tickets online in advance. It saved me some time in line, and I got a small discount. Every dollar counts, right?

Consider bringing a water bottle. I thought there would be more spots to drink water, but they’re a bit limited. Staying hydrated makes everything more enjoyable!

I recommend visiting early, around 8 AM if you can. There are fewer crowds then, and you can enjoy the cavern in peace.

My advice is to wear good walking shoes. Some paths can get slippery, and you don’t want to risk a fall while marveling at the views.

Consider buying a national parks pass if you plan to visit other parks in the area. It saves you some cash!

If you're planning to take a lot of photos, a lightweight tripod is a lifesaver. The lighting in there can be tricky, and you’ll want to capture those stunning rock formations without blur.

If you're interested in photography, I recommend the 'Historic Tour' as it has some stunning sights. Just be aware that flash photography isn't allowed!

Get your tickets online before you arrive to save time and avoid long lines. I waited an hour to get my tickets, which cut into my exploring time.

Pack a light jacket, even in summer! The cave can be chilly, and I wished I had one for my visit.

Make sure to get your tickets online ahead of time... There's no line for digital tickets, and you can save some cash on combo packages if you plan to do other attractions too

I found the ponchos they give you surprisingly useful, but bring a backpack for extra clothes! I wish I’d thought of it, ‘cause I was soaked and cold afterwards

Be ready to hike up and down the stairs! The views are worth it, but my legs were killing me after. I think taking your time helps you enjoy the scenery better.

My advice is to visit on a weekday, specially Tuesday or Wednesday. The weekend crowds can be overwhelming, and you’ll get way better photos without a bunch of other people in them.

Be ready with your camera! The views inside the caves are stunning. Just watch for some low ceilings and awkward angles—I bumped my head a couple of times!

I think visiting during the weekday was a great choice. The crowds were way lighter, making for a more enjoyable experience. If you can, hit it up on a Tuesday or Wednesday!

If you're on a budget, grab lunch in the town nearby instead of at the park's cafe. You can find some cute diners with tasty food for half the price!

I recommend taking the guided tour rather than just wandering. The guides are super knowledgeable and share some awesome stories that make the experience more memorable!

I suggest booking your cave tour in advance, especially on weekends. I had to wait an hour extra 'cause they were sold out for the tour I wanted.

My advice is to wear good walking shoes! The trails can be uneven, and I regretted my choice of flip flops halfway through the cave.

I recommend bringing a water bottle and snacks. There are not many places to grab a bite inside the park, and I was starving after the tour.

I recommend wearing layers. It gets chilly down there, even in summer! I was surprised how cold it was in some parts

My advice is to bring some snacks. The food options inside are kind of limited and pricey, so having your own snacks can help save some cash.

My advice is to book your tours in advance, especially during summer weekends. I got lucky, but I saw some folks disappointed because they couldn't get in

I recommend wearing good shoes because the cave floors can be slippery. I saw a few people struggling and it slowed things down.

If you're looking to save some cash, pack a picnic! The views are so nice, and there are great spots to eat outside instead of spending at the visitor center

I think you should definitely make time for the scenic drives in the park. They're breathtaking and a nice break from cave exploring.

If you're going for the best pictures, bring a good camera. The lighting is a bit tricky in the cave, but the falls are super photogenic when you get the angle right!

Wear comfortable shoes! The paths can get a little slippery and uneven, so you'll want to be sure you're steady on your feet.

Plan to wrap up your visit by 5 PM. That way you can catch the sunset views from the lookout—it’s absolutely stunning!

I think visiting during the week is a good idea - it's way less crowded. Even a Tuesday or Wednesday can feel like you have the place to yourself!

i recommend heading out early, like around 8 am, to avoid the bigger crowds and enjoy some peaceful exploration. the sunrise over the well is stunning, too!
