When we visited Watkins Glen State Park in early May, we were only partly lucky. The first third of the Gorge Trail was open, so we did see many interesting waterfalls. Unluckily, that meant we couldn’t see Rainbow Falls and a few other falls from the Gorge Trail. The view of Rainbow Falls that we got from the Rim Trail wasn’t bad at all, but I’m under the impression that the cool part about Rainbow Falls is being able walk underneath the falls. We weren’t able to do that. Oh well. I would suggest visiting later in May, even though the park is open in early May and all of the snow is melted by then.
1) Watkins Glen State Park is directly off of NY-14 in Watkins Glen.
2) Pay the state park entrance fee, and then park.
3) Rainbow Falls can be seen from the Gorge Trail or the Rim Trail.
