If you are looking for a fun and unique activity in Minnesota, look no further than Niagara Cave! This is about 2 hours south of the twin cities in Harmony, Mn. As I was driving I almost missed it, as it is mostly farm fields and this place is well hidden by trees! Once you pull in the driveway, it really opens up to a beautifully kept property!! There is the cave experience(hour long) 9 or 18hole mini golf and an area for panning (you buy a bag inside the gift shop and do the panning outside in front of the building) My boys (7 and 3) and I only did the cave experience and it was very cool!! There are about 275 steps that you do through the cave and then you walk back the same way,so about 550 total steps. Some of the areas can get narrow but are doable. I am 5'7 230 pounds and did fine, but if you have a larger stomach, some of the areas could get tight! Our guide was Parker and he was very sweet and answered everyone's questions to the best he could. He also had some jokes which added a lighthearted vibe to the tour! Definitely wear good shoes (no crocs or sandals) and bring a jacket or sweatshirt as it is always 48 degrees in the cave! Also, it is not expected but it is always nice to tip (in cash) at the end if you liked the tour! I didn't add all of the pictures I took as it would take away from the initial experience, but this place was very fun! There is also a picnic table area and a small playground! There is a gift shop (I know parents, our favorite thing right?? Haha) but things were VERY reasonably priced! Way better than most gift shops I've been to! Both of my boys got a souvenir for $10 a piece and there were even cheaper items! If you haven't been here, definitely put this on your Minnesota bucket list! This is an absolute must!! read more

I have done a number of cave tours as they travel a lot. This one's a pretty easy tour a flat ground lots of stairs but doable. We had a nice young knowledgeable tour guide. It was interesting. I must say something to do in harmony besides the Amish tours it was worth it for sure you go about 200 feet underground and it's a mile long I went on Saturday tours were about every half an hour. I didn't pre-pay. I just paid when I got there. Wasn't sure what time I'd be there. read more

I love visiting caves and Niagara Cave near Harmony, MN was a real treat! Quite a good walk with many stairways down to its 200ft low point. High points were the platform over the 100 ft waterfall and the deepest end point. Definitely recommend and I was happy to see the metal doors sealing the cave off! read more

I loved the one hour tour . Our guide did an awesome job. It cost only $20. We got there early and they were able to get us in an early tour. They have a free parking lot. Drinks, foods,and backpacks are not Allowed in Cave. So make sure you eat and drink before hand. They have a lot of fun stuff to do with the kids. read more

ECHOLOCATION, ECHOLOCATION, ECHOLOCATION *This is a belated review for a family member's wedding held here. VENUE AND CEREMONY: When it comes to weddings, it's all about a gneiss location. Some couples get hitched in a church or on a white sandy beach. Others take the party underground to exchange sweet sediments. Niagara Cave's Crystal Wedding Chapel creates an intimate experience with a unique backdrop for a happy couple and their guests. Only about 20-25 people fit in the chapel, but don't quarry! Extra invitees can still hang stalagtight-style out in the walkway. DRESS CODE: If you are down to get covered in brown--200 feet deep down, to be precise--then have guests dress to get grubby. Things get dirty down in the cave! Not Sharon Stone dirty, mind you. Mud and water splashed up your pants dirty. Batman capes or raincoats are also encouraged to protect from cold water dripping down and to keep warm in the 48F cave temperature. SPECIAL INSTRUCTIONS: Walking conditions might be prohibitive for the elderly or claustrophobic as there are about 550 steps round trip combined with sloping floors and narrow passageways. On the bright side, if one senses the walls caving in, looking up at the 100-ft-high ceilings should help relieve the feeling. Post nuptials, guests are cordially invited to tour the one-mile-long cave and revel in awe of the 60-ft subterranean waterfall, 450-million-year-old fossils, limestone rock formations, underground river, and echo CHAMBER... CHAMber... CHamber... chamber! What better way to celebrate a union of two people than to be surrounded by such epic history and beauty. Overall this is an adventurous way to celebrate the big day with friends and family. It rocks and I give it 4.5 Captain Caaaaaaaveman hollers! read more

The absolute definition of a hidden gem, Niagra Cave was such an immersive experience on all fronts. We were incredibly close to the rock formations and waterfall. Our guide Michael was absolutely phenomenal, constantly answering our questions and engaging with us whenever possible. Give him a raise. Overall would definitely recommend this for anyone who is able to climb and descend the steps. It's a really breathtaking experience. read more

Niagara Cave - Tours Near Me - Harmony, Minnesota

Scenic tours every 20 minutes lasting over an hour. Some elevation change and many stairs but not very strenuous. Waterfall, lot of dripping water, quite wet. Underground slot canyons i.e. high narrow passages that were not claustrophobic for me. Unusual fluorescent and phosphorescent calcite. No resident bats, so there are no restrictions on visiting this cave if you have previously visited a cave that has bats. For that reason, visit Niagara Cave before you visit Mystery Cave. If it is open during winter, this is a mild place to go, about 48 degrees F! read more

Went in September. This was an amazing experience! The photos posted and the ones you take while you are in there can't capture it. You take a really long staircase deep into the earth. Bring a jacket, hat and gloves... Not kidding. 45 degrees in the damp dark is bone chilly. If you have asthma you might have difficulty breathing in the first large cave area where there is a waterfall crashing and spraying... Once you get beyond that it gets easier to breathe. BUT, after that area, if you are claustrophobic, beware the rest of the tour is the longest skinny crack hallway of all time. Because it is very, very tall, just look up and it won't feel so tight. It is a oneway so if you need to go back in the middle of the tour you can't get lost. There are a couple other small openings, but you are deep in a giant rock crack by a water table in the Earth... There are no creatures as this isn't a regular cave, but there are some fossils in the walls. It wasn't open to the surface at all until its accidental discovery when a farmer's sheep went missing. It had slipped in when part of the turf parted. You can learn tons more on the tour. The tour guide was a college kid who grew up in the area and works here seasonally. Really personable and knowledgable! If you get to this area, I would recommend you visit! read more

Ever imagine yourself as Indiana Jones? How about being Indiana Jones in an Amish town where your trusty steed is a tractor? If the answer to the latter is a resounding YES, then Harmony is the town for you. Not only will you find yourself in the midst of a scenic landscape, you can also live out your fantasy at the Niagara Cave. Even as an adult, you can still feel the sense of childlike wonder as you step into the entrance chamber that leads you into the cave underneath. Everything there seems to take you a step back to the land before time. Just glance up at the ceiling or look at the cavern walls. There, you will witness the fossilized remains of some living organisms that existed millions of years ago. If that's not enough to make your jaw drop, the underground waterfall and geologic formations of the stalactites, stalagmites, cave bacons, cave straws, and many more will keep you entertained. It's not everyday that you can find a waterfall, let alone in a cave, which is precisely why this gem is such a remarkable place to visit. If you're planning to go there, be aware that there will be lots of steps to take before you get into the cave. Some areas will also be quite a bit of a tight squeeze, so if you're built like a linebacker or sumo wrestler, this cave might not be it for you. For everyone else, the Niagara cave is an experience not to be missed if you're in the area. read more

One word to some it up ... WOW , this was an amazing experience ! It over 200 ft down there is a waterfall raining in an abyss (hence niagara cave) we got a tour guide to take us (with a group) down. Not to easy to find but really worth it they have mini golf outside and a consesion stand , but it's pre-packaged foods. They have a gift shop with clean bathrooms . To sum it up this really was worth going out of are way to see! read more

It's one of those times you want to give a place three-and-half stars, but I decided to give these guys the benefit of the doubt. (so I guess the next person on the fence should give it three, to even it out. Heh). Headed here because due to a state government shutdown, the nearby Mystery Cave was closed. The Niagara cave is so called because of the giant (60 foot?) waterfall that is INSIDE THE CAVE. I've been to a number of publicly-accessible caves over the years. Compared to those, Niagara is more interesting in some ways, less than others. It's a very long cave; instead of a bunch of rooms, there are a few very large rooms, and then a lot of thin, but very high-ceiling-ed (up to 100 feet) passageways. Because of this, walking through Niagara cave often looks like walking through an Arizona slot canyon, which is extremely cool. There are basically two large rooms at either end of the slot-canyon like passages - the first one is the waterfall room, which is amazing. The second is at the far end, and is the room most full of traditional cave formations (stalactites, etc.). Other than that, this is a fairly young cave, so there are actually not a ton of those kind of formations around. The staff at the site was very friendly, our tour guide was GREAT; a college kid who grew up in the area. The store up top has a nice shop, with both fancy mineral specimens and plenty of cheaper knick-knacks. If you've got kids, they sell bags of mineral specimens in sand that you can then "pan" for outside in a neat water sluice running next to the shop. There is a nice green area outside, with picnic tables. I could easily see bringing a family here (and indeed, many people did). So, in short: a solidly nice tourist destination, certainly worth the 11 bucks to get in (full adult price, kids and seniors cheaper); not one of the wonders of the world, but a good place for families. And really, that waterfall is pretty freakin' cool. read more

What a fun family excursion! From my 5 year old all the way to the adults we loved it! Be prepared for chilly temps (48) and wet environment. Tennis shoes are a must. You also do a LOT of stairs but they are spread out enough that, for the most part, nobody in my family complained! read more

Called ahead for our tour time. It's was pouring rain so we got stuck waiting in the gift shop with everyone else. It was super crowded. Tour was great!! A LOT of stairs. Narrow passage ways at times. I'm over weight and I was able to maneuver through no problem but the stairs were a little bit of a struggle on the way back up. I definitely recommend this activity!!! read more

Stopped here today on the way home from visiting family in Iowa. I gave it 3 stars to even things out as Scott suggested, and b/c I don't think its quite worth 4. =) Scott's description of the cave innards is really good. My kids and I thought it was a neat visit. It was about a mile walk and took around an hour. I certainly would not make the drive from the Twin Cities just to visit this place, but if you're in the area its worth the admission price. There is a little playground for kids and plenty of picnic benches and shade trees. We had a nice picnic outside. If your kids are into the panning for jewels, I would recommend buying one of the lower-priced bags. We bought the Emerald, which is the most expensive at $11 and it def was sub par comparing with the dozens of others I've purchased at other caves and pumpkin patches (my daughter fancies herself quite the miner). read more

Great family attractions, well managed, a safe and interesting tour. Cave was well taken care of and had a cool waterfall and more.

This was another stop on our cross country drive. I admit that we only came this way because the Spam museum was closed and a family member suggested this instead. This was interesting. These are guided tours given at certain times so you need to wait for the next tour. They have a little gift shop to browse and a playground outside as well as a water thing similar to panning for gold and I think a mini golf area (we didn't do this). The guide was great except if you are here and getting a geocache our guide didn't know the names needed.... hint... they are in the book about the cave located near the cash register. I didn't buy the book, just snapped a photo of the page I needed so I would remember. I thought this was a neat cave, quite extensive. As always, I brought my own flashlight so I could look at things without the guides. There are lots of stairs in here so if that's a challenge I wouldn't suggest this one. The one big negative I would say is that we really felt very rushed through this tour. I had one child in a carrier and our other was walking/being carried and it really was too fast for us. Bring a jacket, it's cold down there! read more

Excellent place to visit for all ages. The new mini golf, tour of the cave, gift shop, refreshments, picnic area, and panning for gem stones. The owners and staff at the cave are top notch. Plus Harmony has several restaurants, movie theatre, large antique mall, and many other things to do. read more

I've been here three times now, and I'm just as amazed every time! The tour guide this last time seemed really new and awkward, but they've all been really interesting and knowledgeable the times before. The gift shop has some awesome stuff to check out as well. read more

We were so happy we added this stop to our trip. My family enjoyed the cave and the interesting facts the tour guide gave us. The wishing well and waterfall were amazing! Also it was fun to look at the cool shapes in the cave each one with a story. It was cooler down there but with so much walking and stairs our kids didn't complain (they were in shorts and t-shirts). Make sure your kids use the washroom cause its a long tour if someone has to go. Of course there is a gift shop, we found cool patches to buy after the tour for our cub scouts. We skipped the mini golf but had $1 ice creams and we were back on the road. read more

We had such a fun time here! Tour guide was excellent and really made the cave so much more interesting for us!!

Great place to visit! The staff were friendly and the tour guide my family had was very knowledgeable. The grounds were clean and provided a great place to have a picnic. read more
