Wellfleet resident here. Nice place :) The Outer Cape towns (Eastham, Wellfleet, Truro) are quieter than the rest of the cape. We have nice beaches on both the bay and ocean sides. We actually have a small downtown with (mostly seasonal) shops, galleries, and restaurants. One of our claims to fame is being the site where Marconi did his first experiments in transatlantic radio.

The "seasonal" part is important; the outer cape is hopping in the summertime with visitors and summer residents, but is much quieter in the winter. Not as quiet as before, though; during the pandemic a large number of people moved to their summer places year-round and the year-round population is a bit higher than it used to be...

A couple little shops near the harbor, nothing special, but the ocean side is a national park with a scattering of grandfathered houses, no new development since 1961. So the renovated houses with cliff views that aren't about to fall into the ocean are rather expensive. Great cycling, great birdwatching, and an astonishingly good French bakery.
