This section of the Farmington River is mostly flatwater/quickwater paddling with the exception of two notable whitewater stretches.
The first, which contains 'Crystal Rapids' starts near the begin of this section and continues into Unionville (class II).
The more famous Tariffville Gorge is near the end of this section. Rapids here range from class II to III+, and can be even more challenging at higher water levels. Only experienced paddlers with whitewater boats should enter the gorge. (National Park Service)
