They are open. You just cant drive down the canyon road. You have to park at the top or the bottom & walk into the canyon road area where the rock ledges are located & the water streams.
Sure are! Weather events can often cause temporary closures of the park to vehicle traffic, but the canyon drive is usually always open to foot traffic. You can check before you go here: https://www.iowadnr.gov/Places-to-Go/State-Parks/Alerts-and-Closures
They are open everyday of the summer
