I decided to follow the hiker's map and it was a very bad idea. Most of the time I was searching for the trail and a 5.3 mile "loop" turned into an 8 mile fiasco with a dangerous section walking along the railroad track and no clear trail near it. Dogtown itself is interesting but the trails really do stop all the time at which point you have to cut through some hairy parts of the woods.
The trails were pretty. I didn't really find the "lake" mentioned in the description, but I did not go down all trails. The low rating is due to the very large amount of broken glass on some of the main trails- so much that it couldn't be easily avoided. I went on the trails with my two dogs and found myself panicking when I realized we were surrounded by broken glass... Otherwise, the trails are obvious, well marked, nicely labeled, the scenery is beautiful and the location/parking is super convenient! I just would be careful with dogs- be super vigilant or put some dog boots on them.
