The best vantage point for Erendira Wallenda's helicopter stunt Thursday morning is Terrapin Point, at the west end of Goat Island beside the Horseshoe Falls.
State Parks officials said spectators should try to arrive by 8:15 a.m. Parking will be free before 9 a.m. in Lot 2, near the Top of the Falls restaurant.
The plan calls for the helicopter to hover about 300 feet over the Falls, which should be above the mist.
The stunt is expected to begin about 8:30 a.m. and should be over in less than 10 minutes.
