Hike

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.

Greenbelt and North Shore Nature Programs team up for this event for all ages! What sound do frogs make? Turns out, they make a lot of different sounds! Come meet the residents of the vernal pools to learn who says ribbit, quack, chirp, peep and more!

Coastal views with a side of shipwreck! Families will be guided on a Castle Hill hike through the salt marsh, dunes, and beach, while learning about local nautical history, including the role of Fox Creek Canal and Robinson Boat Yard in the area’s shipbuilding legacy, and the fascinating tale of the schooner Ada K Damon, wrecked on Steep Hill Beach in 1909. Participants will have the chance to make observations and measurements of the shipwreck, to learn how marine archaeologists and the Trustees are working to research and protect such artifacts.
