This thread hasn't seen much action. I think Highland Lakes State Park (aka Camp Orange) is a bit of a "hidden treasure". I almost never come across another rider when I am there. Sometimes in the Tamm's Rd. parking lot I see a car or 2, but usually I have the whole place to myself. Then again, I ride a lot during the week.
🙂
There are no maps I have found and very few trails are marked. What markings you may find are either left over from a former routing of the Long Path or someone went through a trail with a rattle-can. Even the latter may only be marked on 1 side of the tree. But, there are lots and lots of trails. And its not all double-track by any means. In fact, there is a ton of single-track to be explored. It is fairly well maintained - not sure if there is a group doing it. I do "rolling TM" myself.
So, I went for a ride there yesterday with the intent to map a good route that I could share with you all. This starts at the lot on Tamm's Rd, which has parking for 15-20 cars.

If you are able to put this in your GPS, I think you will find it a mostly enjoyable route with only 1 notable climb (from mile 7.3 to 8.3 on track). But, even that is a rideable climb if your fitness is decent. This is a good taste for the root-covered single-track you will find here. And this is just the tip of the iceberg. Following it in the direction I rode it is best.
There are a lot more trails than this. Below is another loop I rode not too long ago that has some common trails to the link above, but a different starting point and some other trails. Only about 3 cars can park here.

Feel free to explore and enjoy!
I intend to do the same for Goosepond Mountain State Park once I can clear (lots of overgrowth) a continuous route I think you might like. Its another fairly unmarked location and my recent TM efforts have landed me with a bout of poison ivy.
