Wellfleet and nearby Outer Cape towns have many wonderful opportunities for kayaking. The harbors, tidal rivers and lakes provide a wide variety of kayaking experiences that range from easy to more strenuous. The variation between low and high tides can be as much as 12 feet. This makes the tide a consideration in planning these trips, and the trips are never exactly the same. Some trips are only possible at high tide. Others, like trips to Billingsgate Island are only possible at low tide, since the island is underwater at high tide. When planning a tidal trip consult a tide chart.
