This is a classic run in Delaware Water Gap - and for good reason! As you climb to the summit of Mt. Tammany, it is easy to see why this is such a popular loop, as you are greeted with stunning views of the Delaware River, Mt. Minsi, and the surrounding wooded hillsides. While this is one of the more challenging runs in the park, the views are well worth the effort.

Need to Know

Restrooms located at trailhead; the trailhead parking lot fills quickly on summer weekends.

While you can run this loop in reverse, it is recommended to run up Red Dot Trail and down Blue Blaze Trail as Red Dot Trail is steeper and most people find it harder to descend.

Runner Notes

This loop is very popular. Plan to run early, during the week, or during the off-season to avoid the crowds.


You can park at either the Dunnfield Creek Parking Area or the Red Dot Trail Parking Area. Start your excursion on the Red Dot Trail. Follow the red-blazed trail past the junction with the Red Dot Trail Parking Lot Connector and up a steady climb. Continue climbing the ridge, taking your time to slow down and enjoy the beautiful hardwood forests around you while you catch your breath.

After a mile of strenuous climbing, the trail grade becomes gentler, allowing visitors to breathe easy for a short while before their breath is taken away by the jaw-dropping views available at the overlook located on the summit of Mt. Tammany. Be sure to spend some time to take in the outstanding views of the Delaware River and Mt. Minsi which are especially breathtaking in the autumn.

Sadly (or thankfully, depending on you point of view), the climb on the Red Dot Trail ends at this point. Once you are done taking in the views from the summit, continue onto the Blue Blaze Trail. While this trail is still challenging, it isn't as steep as the Red Dot Trail, and the opportunities for striking views along the way make it all worthwhile.

Once on the Blue Blaze Trail, run along the forested bluffs of Mount Tammany for a half-mile, before turning northwest and beginning a considerable descent through beautiful hardwood forests. During the fall and winter, watch your step as the descent can often be covered in slippery, wet leaves.

After a mile of descending, the trail grades soften, allowing visitors to fully enjoy nearby Dunnfield Creek. At the junction with the Appalachian Trail (AT), continue south, following the trail downhill toward the parking area to finish your run.

Flora & Fauna

Mixed hardwood forests surround this trail, with white oak, red maple, and shagbark hickory in abundance.

I enjoyed this trail. Very rocky, with typical sizes varying from large boulders to shoe sized rocks (with plenty of sizes in between). My first ascent was walking up the Red Dot trail with my family. We took plenty of breaks, but we made it to the top in under an hour. As the fam ate lunch, I decided to see ehat attempting to run up the Red Dot trail might be like (knowing it was a steep beast). I descended in approximately 25 mins, and it actually was not too bad of a hike (I never really ran down — it was more about making smart foot placement and keeping my balance. I imagine it can be done much faster, but I still don’t know that I would consider it a run. At the bottom, I stored a jacket and turned around for a second ascent. The first quarter mile I was actually jogging. Eventually, within the next quarter, the trail becomes more of a stair stepping exercise. I would run when I could, but I would not consider much of the trail truly runnable. A great workout, yes. I made it up in 23 mins. I imagine some speedsters could do it in 13-15 range. They would certainly be running the entire time, like a fast mountain goat. Descending the Blue Blaze Trail loop actually seemed more difficult than descending the Red dot. The rocks were smaller, but much more diffivult to take big safe strides. This lasted for a good portion of the trip down. I’m not sure running up the Blue Blaze trail loop would have been much easier than the Red dot. Running down was not much of an option in my opinion, so I hiked fast. I was trying to catch the family, so it would have been nice had the rocks been very small. Mother Nature chose otherwise. This was a very atypical trail run for me since it was fairly steep, but it was really the overall quantity of rocks that creates a higher risk of injury for ankles and knees that make this a better “speedy hike” or mix of run+hike. Overall, I enjoyed it and glad I chose to head down and back up the Red dot trail at a faster clip the second time around. During the weekday, parking was plentiful and there were probably only 25-30 other people out and about. Oct 16, 2018
