Visitor Tips and News About Fish Windows
So much scum. Don't waste your time.[Samantha, 11/08/2014]
Windows were pretty thoroughly covered with dirt, scum, and graffiti. Only the upper 1/6th or so of the windows remain unobscured. No fish viewing is possible. Still kinda neat tho.[Jon, 10/13/2014]
Just lots of algae and scum buildup on the fish windows, and pretty brown water.[Mike & Nancy, 10/02/2010]
A custodial crew was on site cleaning up the area, as well as some landscapers...looks like they're trying to make the place more presentable. Benches on site.[Taryn Bays, 07/16/2009]
Boulder Creek Stream Observatory - Fish Windows
Boulder Creek Stream Observatory is along the Boulder Creek Trail. This fish observatory was built to display the underwater life. You go behind the Millennium hotel toward the creek, down a few steps, and you'll be below water level. There's a cement retaining wall with circular windows that allow you to see underwater. If you're lucky, you'll see some fish, but usually you just see algae scum build-up on the windows and pretty brown water.[Laura Bloom, 11/12/2006]
