Journey Behind the Falls to be limited for 2 weeks
From the Buffalo News:
The Journey Behind the Falls, a tourist attraction that provides views from behind and beside the base of the Canadian Horseshoe Falls, will be closed to visitors or will have limited access during the next two weeks as the Niagara Parks Commission conducts its annual spring maintenance along the rock wall of the Niagara River gorge.
Note: This article is from April 14. The attraction is closed entirely this week.
