With daughter and two grandsons, my husband and I loved our time at Pebble on the Bay. The location was quite close to Stillwater, so we were able to easily provision our stay but also able to enjoy several meals at good restaurants. The cabin was very well outfitted with full kitchen, water toys, indoor games, and reading (though our weather was perfect and we spent most of the time in the water.) Paddleboat, kayaks, and swimming from the floating dock were the kids' favorites. We even saw a pair of loons! Oh yes, and net-fishing from the sandy beach. The big surprise - we had NO mosquitos.
Parking by the side of the road leads down a sturdy and well-lit staircase with good handrails.
