East of Dover, Delaware, Port Mahon Road extends nearly four miles from Delaware Route 9 toward the remains of an old fish factory and adjacent piers along the western side of the Delaware Bay.
The area is an excellent bird watching area and is near the ponds and marshes of the Little Creek Preserve. Since water sometimes covers the road during heavy rainfalls and high tides, there are some eroded areas that drivers must be careful to avoid.
Boulders and large rocks line the bay side of the road, providing protection from washouts and entertainment for the rock hunting set who love to identify all the different kinds of rocks and minerals here that are so easy to access.
Planned field trips for Earth Sciences classes and Geology courses would keep students busy all afternoon identifying the various boulders, and granite enthusiasts might enjoy seeing their granite counter top material in the rough.
One of the nicest things about Mahon Beach is that the road is so close to the water and the water fowl that persons with disabilities and limited walking abilities can observe nature up close from their cars.
One of the disappointing things about this beach is that . . . there is no beach here! There are just a few small coves of sand, covered in stones and cracked shells that the birds have left behind. Bird watchers, however, will enjoy the large variety of shore birds and inland birds present along the bay shore and inland marshes. At the end of the road in the large parking area for the boat docks, there is an osprey nest on top of a tall pole.
The local history of Port Mahon and Mahon Beach attracts history buffs and photographers who reconstruct the fallen architecture while people interesting in fishing the bay today set out from three newly constructed boat launches.
