Because the estuary of the River Fleet is very shallow, tides go out typically for half a mile, and in sunny weather come in over warm sand, which warms the sea quickly. There are few currents of any consequence apart from the river itself. All the bays about Gatehouse of Fleet are very clean. At low tide, many walk out over the sands to offshore islands, but carefully check tide times to avoid getting marooned.

There are almost endless opportunities for walking and cycling in the woods and forests around Gatehouse.
