We are sorry that the tour did not live up to your expectations. We have many stops on this tour and cannot give the amount of time at Multnomah Falls that would be needed to walk to the top of the waterfall. While the interior of Vista House may have been closed, the tour still stopped there and you were able to enjoy the amazing view of the Columbia River Gorge. Unfortunately we cannot control random closures of locations. Those things are completely out of our control and closure information is not always posted online.
