Rocky Narrows Loop

There is room at the trail-head for approximately six vehicles, but is not typically full. The Yellow Trail starts with a slight decline all the way to a set of train tracks. From the tracks you are able to take in great views on the Charles River. After crossing the tracks you are now on the Blue Trail which is where you begin to gain some elevation. There are two locations on the Blue Trail which offer great views of the Charles River from afar. Eventually the Blue Trail intersects with the Red Trail. The Red Trail should be followed for only about 100 feet before keeping right to head towards the kayak landing and campsite. This is a great campsite right on the Charles River and requires reservations. You'll take this back to the Red Trail and turn right, following for about 1/4 mile before reaching the Red/Orange intersection. Keeping right will put you on the Orange Trail which is a very dense portion of the trail and is somewhat boggy with planks and boards to hike through some march sections. The Orange Trail will eventually take you to the Red Trail again. The trail will pass by another trail-head parking area, which could be utilized of not doing the loop. The Red Trail is then followed through beautiful woodlands until making it back to the Blue Trail, at which point there are a few options to keep right and get back to the railroad tracks. From there the you're tracing your steps back to the starting point.
