Visitor Tips and News About Fish Windows
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 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]
