The Blue trail is similar to the yellow trail in that is has the same distance and terrain. They are short 30 minute walks. The Blue trail can be accessed while walking along the Green trail. The blue trail mostly travels through light forest and decently maintained. The blue trail when started from the green trail lets out at a main road. Which means you can access the inside of the park without parking in one of the parking lots. This is good if you plan on hiking past closing time (Which is not recommended).
