The OES visited the Hayden Falls on June 8, 2004. The falls are off of Hayden Run Road just west of Griggs Dam in the Columbus Metro area and is part of the Griggs Reservoir Park. This beautiful waterfall has to be one of the city's best kept secrets, as many people wouldn't expect such a site in an urbanized area. On our first visit, a few people were swimming beneath the falls and we found that it makes a great swimming hole. We have heard that some people have jumped from the top of the falls into the water, but we would not recommend this as there have been several severe injuries as a result. There is a small pull-off on Hayden Run Road where you can park but use caution when going down the steep hill. After rain, the area is full of water and sometimes impassible. When it hasn't rained for some time, the falls are reduced to a small trickle. Hayden Falls are about 25 feet with a crest of around 10 feet. It is definitely a place to check out if you live in the Columbus area.
