SubTropolis

Place is well organized,parking lot outside you walk up to the guard and ask for directions which is the best way to go about this! Don't even think of trying to go inside by yourself If you're not familiar with this place.
I unloaded in a couple of companies located here and it was pretty fast,it is a great experience but be careful.It is a super tight place,lots of docks are blindside parking.
Good luck!

One of a life time to deliver inside this place. Not that much room to back up my big rig into their dock but every one was patient enough to help. Cars drivers were very respectful on giving trucks space to move in there. Thank you.

Tip for truckers.... there is a staging area right next to railroad tracks across gas station Huge lot right next to it there's a big billboard with the name of the businesses which is inside the cave before you go in call the security guards to find out which is the best way to get to the business what you need... once you loaded ask the locals which is the best way out it maybe the different from the way in...

The fact that it is underground and it's like a maze makes it difficult to navigate to where one is going the businesses that reside there the people actually are very very helpful in helping someone navigate to where they're going by giving very good directions at the guard shack they give directions and they show you a map my first time there it was difficult even though I had looked at the man in the people that work at the businesses there help me out greatly I would say everybody at the whole facility are very wonderful

Love this place. Do a lot of business in this cave. They have a lot of space to work in and out of. Great people..love security they are very nice people .

This place was awesome to visit. I enjoyed the experience.

Natural environmental protection and security and a very high level of service. SubTropolis sets a great standard for warehouse and distributions space.

So apparently this is the largest man made cave in America. It's massive. You could get lost in here really.

Cool place

Staff, everyone of them, friendly, courteous and professional. Safe place to store.

Very friendly and helpful management and staff.

I've never been here but I can't wait to visit based off the videos I've seen!

Great place to run a business..everyone is friendly

Best place to work

That was a really spectacular one-of-a-kind place.

Many settings to chose from. Small or large; they have it all for your business needs.

Tight but cool as hell. No service at all

The 2013 Groundhog Run was absolutely spectacular!

Reasonable prices for underground storage space
