Falling Waters State Park to see Florida's highest waterfall. The waterfall is actually dropping 70 feet into a sinkhole. The park is riddled with sinkholes, we saw maybe 8 or 10 in the area of a few hundred feet. This waterfall had lots of ferns and mosses growing along the sides of the sinkhole. Once again, it's winter, one of the coldest days we've had so far, and we have the park to ourselves.
