Alan:

The attractions at Tivoli are the Saugerties lighthouse, the fresh water tidal
bays south of there which are delimited by the railroad causeway, and several
islands. The bays are sorrounded by parkland.

Its an interesting ecosystem in that hardwood forest comes right down to the
edge of the marsh, and the marsh is unique due to its fresh-water-tidal nature.
Archeologists have surveyed the islands, and evidence of activity that depended
on the fishing and shellfish goes back about 8,000 years or so. If you run
Tivoli Bays on Google, you'll turn up a bunch of stuff on both the ecology and
the archeology.

There's a put-in right where the main drag meets the railroad at the edge of
the river. It's an enjoyable trip which is made better if you do your homework
first to appreciate the history and ecology.
