Honeymoon is man made, the rocks are in the water to keep the trucked in sand in place. Dog beach is/was the SE tip of honeymoon on the bay side.My parents lived in Dunedin for 35 years and we visited often.

Fred Howard park is natural as is Caladesi. No crowds on Caladesi.
The Beach on Sand Key ,just South of Clearwater, is less crowded but not many concessions and you have to feed the meter to park.
