Hike, Walk, Run around Niagara Reservoir.
If you park at the Power Authority parking lot, and take paved trail up onto reservoir embankment, you can walk around most of the way. If you go counter clockwise, following the mile markers, around 6 miles you will come to a "no trespassing" gate. Go through it, and at 6.5 miles, just before the dam, on the right you will see a radio tower and a little dirt path that goes out by a cematary on Witmer Road, go out that way (steep climb down the embankment to path), turning L on Witmer and cross in front of the dam on Witmer road back to the parking lot for a total of 7.3 miles. Or do it in reverse, going in front of dam on Witmer, turn right on dirt road by cemetary . . .
