I stuck to Commercial Street, first walking all the way west to where it begins near the spot where the Pilgrims first landed in the 1600s (it wasn't at Plymouth, but Provincetown - they moved on to Plymouth a little later). At the spot historians determined is likely the one where they made their stop, there's a plaque and a small park (Pilgrims' First Landing Park). Off the park, a small beach and a jetty made of large rocks.
I walked out onto the jetty for a while. I loved listening to the water rushing under the rocks (where I also found some smashed shells, probably from sea gulls dropping them on the rocks to get at the meat inside).
And I loved the smell of the salt marsh all around.
As for walking along Commercial Street, I loved the flowers and greenery in front of shops, homes, and inns.
So many little corners, arranged for comfort. And places that invite you to relax or explore (I had to remind myself a few times that I was staring longingly at private property and couldn't just chill out on a lounge chair whenever I wanted).
I did find a wonderful place to relax for a while - the Provincetown Public Library, which is grand.
On the second floor, and soaring into the third floor, there's a half-scale model of a schooner, the Rose Dorothea.
There are awesome views of the Provincetown harbor from third floor windows.
And the library also displays art (this time around, works from Naomi Lebrescu, Mirel Bercovici, Konrad Abbott, and Mirana Comstock).
Along Commercial Street, you'll also find many art galleries, like the Tao Water Gallery:
and the Bowersock Gallery.
Public art too, like "Tourists" by Chaim Gross.
And lots of color, everywhere:
