Take first exit after Sagamore Bridge and follow 6A east. Follow 6A through Sandwich village. In about 3 miles you will go by a jeep dealership(on left) Creek is just ahead, turn right for access to the upper stretches. For access starting at the mouth of the creek one would have to take a left (opposite Christies market) about a 1/2 mile earlier. Follow road to a T intersection at Beach Realty and got right. Near the end is a road that turns to the right towards the marsh. Here's your access. Wading out on a falling tide in the evening can be quite productive (or so I am told)
