We will forward the comments to the maintainer(s). The white blazes with blue and red crosses are the results of mild vanadalism: somebody has (neatly) painted these crosses in our white blazes. I was early this spring on the trail and thought then that the number of blazes was adequate.
The fact that there is not an end-of-trail blaze near Huckleberry Ridge State forest is an oversight, and we will correct it. Sorry for the inconvenience. The plan was to extend the trail to the SRT, but the forest managers blocked this plan for the time being. We will also update our online SRT map to reflect the current route of the Lenape Ridge Trail.
I'm glad to hear you think it's a beautiful hike.
Thanks for the comments, Jakob Franke
Admitting first that I am a novice hiker, I would like to comment on this loop.
First, parking at the trailhead is severely limited. I have a Honda Civic, and it barely squeezed into the small trail opening so it was off of the road. If the "P" symbol on the map refers to some other nearby parking area, it should be described in the driving directions.
Once on the trail, I found the Lenape Ridge Trail to be inadequately blazed in places, compared to other local hikes that I enjoy. Frequently when we were at one blaze, we had to wander a bit in several different directions before the next blaze came into view. To be clear in what I am saying, there were many blazes from which it was not possible to see the next blaze, not because our view was temporarily obstructed by foliage or something, but because it was simply too far away or around a turn. There are also blazes for what appears to be a third trail (white cross on a red background), which is not mentioned in the description of the route. When we reached the point where the Lenape Ridge and Minisink trails diverge at the southern end of the loop, we chose to follow the loop in the opposite direction from how it is described (i. e. clockwise), because the Minisink Trail appeared to be more clearly blazed.
When we reached the northern end of the loop, where the two trails converge, we chose to continue east- and northward, following the white blazes, with the Metro-North tracks occasionally visible on our left. The last white blaze we were able to find was close to the tracks, just beyond a deep ravine with a stream at the bottom. According to the map whose link appears above, we were at the westernmost corner of the Huckleberry State Forest. We spent about a half an hour looking for the next white blaze, before we finally gave up and turned around.
If the Lenape Ridge Trail ends at the edge of the State Forest, then the last blaze should have the traditional "V" shape. It would also be helpful to include on the map the portion of the trail which extends beyond the north end of the loop, for people who would like to lengthen their hike by a couple of miles. If the trail continues into the State Forest, it needs to be blazed more thoroughly beyond the ravine.
This is an enjoyable hike with several beautiful views, but I found it difficult to follow as described.
