The Former Lyman Viaduct โ Hop River State Trail loop from East Hampton offers a truly epic gravel biking experience, combining two of Connecticut's most notable rail-trails. You'll traverse varied terrain, from smooth, hard-packed sections to rougher stretches with loose stones, winding through dense forests, open fields, and along the Hop River. The route's centerpiece is the historic Lyman Viaduct, a massive gravel embankment that provides stunning panoramic views of the Salmon River Valley, making this a rewarding journey for experienced riders.
This is a challenging 53.7-mile (86.4 km) ride with 2667 feet (813 metres) of elevation gain, typically taking around 5 hours and 47 minutes. While individual sections of the Hop River State Trail are easier, the full loop is rated difficult and demands very good fitness. Ensure your bike is equipped with good tires to handle the varied surfaces, especially if you venture east of Andover.
Both the Hop River State Trail and the Air Line State Park Trail are successful rail-trail conversions, offering relatively flat grades characteristic of former railway lines. The Lyman Viaduct itself is a fascinating piece of engineering history, originally an iron trestle that was later filled in to support heavier trains. This loop provides an extensive exploration of Connecticut's scenic and historic rail-trail network, perfect for those seeking advanced gravel biking routes in Connecticut.
