The Kelly Hollow trail is a nice little ~4 mile loop that is a fairly quick drive from our spot in the Catskills. I like this trail because it is easy enough that Lola can still make it the whole way on her geriatric little paws. It also has some nice scenery, despite being closed in on all sides by Millbrook Ridge (I think). B and I had never hiked it in the winter until recently, when some friends of ours were upstate for a holiday weekend. This is typically a pretty popular hike because the trail is so mellow. Amazingly, we did not encounter another soul on the trail that day. I launched the drone over the beaver pond located roughly at the halfway point on the trail. The pond was partially frozen over and had a very cool looking gradient from above. Another cool visual element was that the trees were only snowy above a certain elevation line, but not along the trail (see bottom photo). Here are a couple of the images (our party is in the lower right corner of the top photo, for reference).
