Reviews Summary
Visitors find Tunnel Rock to be a cool and unique roadside attraction, perfect for a quick photo stop and a glimpse into park history. Many appreciate the historical context provided by the information placards and the option to climb to the top for a different view.

"Very cool to see! My husband and my kids climbed on top and we took some pictures. It wasn't too crowded, which was nice. I like that they had some information about it so we could learn how it was made."
Jessica Molstad
"We stayed in Three Rivers and this is the first roadside stop to see. On Sunday afternoon there was plenty of parking open on the side of the street. Includes some information on the tunnel and is popular for photos."
Natalie Bain
"We were here before, about 24 years ago. The park is amazing, the drive is fun. I wish people were mindful of others at places like this though. Please "enjoy" some selfish tourists eating their lunch on top of the rock, so that everyone that visited there at that time has these 2 in their pictures.
Otherwise- definitely recommended."
