A pair of low concrete amphibian tunnels under Henry Street in North Amherst, marked by small signs. On any given day they are not much to look at. On a rainy night in late March or early April they are the scene of one of the strangest sights in Massachusetts: dozens of yellow-spotted black salamanders crawling across the road and dropping into the tunnel mouths.
The annual Big Night, when the migration peaks, is organised by the Hitchcock Center for the Environment with volunteer crossing guards. Bring a torch and warm waterproofs. Outside spring, the site is more of a curiosity than a destination.
