The idea is fun: a sunken area next to Boulder Creek with windows so you can see under water. Unfortunately it's hard to see through the windows, they're not well maintained, lots of sediment on the water side, and scratched up on the dry side....More

A view into the creek could have been a good diversion. Unfortunately it's hard to see through the windows into the creek because they are filthy as other reviewers said. To top it all the viewing platform has an inch of brown gooey mud to...More

Good idea, poor follow though. Probably there was a designated cleaner of the windows at one time, but no longer. So what do you see, a murky creek, which is not really interesting at all. Also just now with the creek running so high, you...More

I remember when it was newer, back in the late 80's early 90's. You could see very clear and the occasional trout would swim by. Then again I remember a much different Boulder in the 70's and 80's. Oh well still worth going and the...More

They don't clean the windows and therefore you can't see anything. Might be a good idea if they maintained it. That's half an hour of my life I'll never get back.

Stopped by here today after being told how to find It by my son. You park in the back lot of the Millenium Hotel and walk down to The creek. There are 4 windows but they are really dirty and you can barely see anything....More

We rode down the path specifically to find this and was disappointed to find that it's just some dirty algae windows.

Don't bother. This is not an attraction. This has been around for a long time. Located behind the Harvest House Hotel (formerly affiliated with Hilton and Clarion, and now with Millennium for the past decade+) along Boulder Creek, an excavation with a walkway in it...More

Difficult to find, and once we got there it looked as if the glass hadn't been cleaned in quite some time -- there are several big, round windows looking into the creek, but only about the top four inches were clean enough to be able...More
