The Catskill Mountains are often referred to as the "little Adirondacks" inasmuch as, like the Adirondacks, it is a state forest with some protected land, a bit of protected wilderness, some mountains / streams/ rivers / lakes, with a sprinkling of small villages / hamlets thrown in for good measure. Unlike the Adirondacks, it a good bit smaller in all of the aforementioned attributes and, in large part, more developed. It should come as no surprise, development wise, since its proximity to NYC has made the Catskills a kind of playground for the big city dwellers.
All told, the Catskills are nice enough, but they ain't no Adirondacks.
In any event, fall color is much in event - measuring 35-50% of peak color (dependent upon elevation) - so I expect to see a fair number of leaf peepers out and about, engaged in their annual orgasmic / feverish fall color picturing mode. Naturally, I do my best to avoid falling into that picture making trap.
