Welwyn Preserve
The information at the Nassau County government website said there would be trail maps. There were none. While the trails are marked with colors, there didn't seem to be any rhyme or reason to the markings. I plan to bring a group of people here as part of a teambuilding event. My work is forest therapy and I will need more information before I can plan my portion of the event; walking the 4 trails at the preserve. The preserve is impressive; the old growth trees are stunning. The trails are clear and easily walked with some hills, but not many.

Unique place
I hiked this park on April 24, 2016. No maps to be found, but an interesting place nonetheless. Supposedly there are 4 marked trails. I stumbled upon 2 of them, but mostly just wandered around. The ruins and greenhouse are worth the visit. Not to mention the Long Island Sound and the gazebo on the jetty.    Check out photographs of this preserve here: https://scenesfromthetrail.com/2016/04/24/welwyn-preserve-county-park/
