I would not go out if your way to visit this site but if you live close or are in the area it is worth spending about 30 minutes there. Its free so the price is right. At the top of the structure its about 750 feet above sea level which is about the highest spot in St Charles county.... More

Eerie, worth the stop. Hard to believe the history of this place, obviously hidden and kept a secret until it was cleaned up. Now we make it a tourist attraction.

A former toxic waste site that was cleaned up. You can learn a little about the contamination, the clean up, and the animals that have reclaimed the area in the information center. The short walk to the top of the concrete shell provides a great view and if you go at the right time, you will be the only one... More

You see a hill, you want to climb it, right? That is what we did. We did not visit the actual interpretive center building as it was early in the day when we went. There is plenty of parking. There were other people there exercising and walking dogs. There was a portapotty available in the parking lot. The walkways are... More

I remember when this really WAS an old abandoned nuclear site. It really was a mess. The fact that the EPA forced a clean-up is impressive, but how they did it even more so. It's worth the visit to the center to read about it. Not everyone will want to travel to the top, but the view is nice. A... More

Why you would make this an attraction I will never know. No one should be visiting this, especially not children. This a nuclear waste site. Yes, they say it's safe but who really knows. People are dying because of places like this. No way, is this ok. Do some research before going and really think about it.

If you like history, this a good place to visit. The waste site is impressively large. You have to walk all the way up though to appreciate it.

The hike up the stairs is pleasant for all ages. The view from the top is so peaceful and beautiful with nice educational stations to read about the history of the site.

Even though they say it is safe, sometimes you got to ask questions. Although compared to how they were disposing of contaminates a few decades ago, I guess we are on the right track. I don't know if I would go out of my way to see this but if near by, it's worth a visit. Interesting, informative and if... More

It's certainly interesting. Walking up to the site that entombs the nuclear waste is an impressive visual. There is a high mound of rocks that you know covers nuclear waste and wildflowers growing all the way around it with cyclists on the trails. You walk up a high set of steps to reach the top where there's information on the... More
