Port Mahon Preserve
Port Mahon Road (Road 89)
Port Mahon, DE 19901
The Nature Conservancy's Port Mahon Preserve is open to the public for birdwatching and nature study. This pristine location at the mouth of the Mahon River makes for a great location to observe spawning horseshoe crabs and the shorebirds that feed on their eggs during the peak spring months of May and June. All we ask is that you please maintain a safe distance from all wildlife to ensure they are not disturbed. That is, unless you happen to see a horseshoe crab stranded on its back; in which case, we ask that you please "just flip 'em."
