Walk

April is the month when frogs, toads, and salamanders return to wetlands and lay their eggs. We'll search the sanctuary's vernal pools, ponds, and woodlands for a variety of amphibians that are the on the move. If we're lucky, we might see Wood Frog and Spotted Salamander eggs and catch a few adults to observe up close and then release.

Each year on the first warm rainy night of spring, wood frogs and mole salamanders begin a mass migration to the vernal pools where they breed. If you happen to be out on one of these evenings, the experience can be like a spectacular amphibian celebration. It's called "Big Night!" For families and kids ages 4 and up.

Named for the host community of Manchester-by-the-Sea, the race provides scenic views. Race through the historic and charming downtown and past the pristine fresh water lakes in nearby Hamilton, MA.
