I was initial warned off of going to visit the museum by my hostel (I'm a solo female traveler and they told me it wasn't safe to go alone), but I decided to brave it anyways and I'm glad that I did. As previous reviews have mentioned, the building and museum are nothing super special (basically just a couple of roofs put up over the footprints) but the footprints are very cool. There are no signs next to the actual footprints (although there are a few in the tiny room with ceramics next door), so I do recommend accepting the services of a guide--the guide is free but they suggest a tip. A few concrete details: it's a $4 US (about 100 cordoba) admission fee, plus another $1 if you want to take pictures. The surrounding neighborhood is not safe, but if you as long as you don't walk around you should be fine--just go straight from the taxi into the museum. I also suggest asking the guide to help you hail a taxi (both the guide and the security guard helped me find one), as they will usually be more than happy to. Coming from Colonia Los Robles (by the Metrocentro mall) I paid 70 cordoba, which you may be able to barter lower. If you are looking to also visit the Port Salvador Allende, it would make sense to combine the museum with that as they aren't far from each other.

If you are interested in archaeology, this is really worth a visit. The museum shows fossilized footprints from a group of people, that were left behind in mud over 2000 years ago. And that's it. There are a few cabinets with artifacts, but nothing really significant. But that really does not matter, it is fascinating to watch all the footprints and realize that they were put there 2000 years ago.

The footprints were discovered in the late 19th century, and they have been studied by archaeologists since. The museum originates from the 1950's and had an overhaul 25 years ago, but it is time again, as it is rather worn down.

While we were there, a guide suddenly popped up (speaking Spanish and a little English), and could explain a lot about the site and the history which made the visit even more interesting.

The neighborhood does not look too safe, take a taxi there and back.

This site was tough to get to, and it was in a tough part of town. I never thought I would see an actual car part burning in the street, but there it was.
The place is quite special. In so many ways you imagine what those footprints represent. Aside from the obvious, one wonders what the humans were thinking or talking about as they walked through, what they may have been doing or where exactly they were heading to. It is made more amazing by the fact that there is another section containing the same prints that were uncovered at a later date. So as the one path ends, there is another excavated area where the path reappears and carries on in the direction of the lake. All of this is viewed from the current level of earth, about 15 feet above the level of the prints. Amazing. This place really does get you to think. So, in a city that may struggle to blow you away with attractions, check this one out. The on site museum and the facility are a bit of a shambles, but this is a very unique bit of history.

The footprints are just that; mummified footprints. Unless you know the history of the place, you may not understand the significance of this place. I had no guide or pamphlet, so everything I learned, I read from the walls. There's a small museum of artifacts. Unless you're into archaeology, you may not find this site impressive or important.
