Located along the Boulder Creek Trail
, the Underwater Fish Observatory is a good diversion to check out if you have the kids with you. They can feed the fish and, if they are lucky, see carp, rainbow trout, and maybe even a cutthroat trout, swimming in the creek. Glass partitions allow you to explore the shallow depths of the Boulder Creek. Unfortunately, the water tends to sometimes be a bit murky. But the kids never seem to mind.
