Pyramid Mountain in NJ is more than just a scenic hike. It’s also a journey through time and space, where you can witness some of the most incredible rock formations that nature has ever created. These are the glacial erratics, huge boulders that were transported and dropped by ice sheets during the last ice age. Some of these rocks are so enormous and bizarre that they seem to challenge the laws of physics and logic.

In this post, you’ll learn how to plan and enjoy a hike on Pyramid Mountain, where you can see three of the most amazing glacial erratics in the state: Tripod Rock, Whale Head Rock, and Bear Rock. You’ll also find out what makes these rocks so special and how they relate to the history and culture of the area.

What are Glacial Erratics and Why are They So Cool?

Glacial erratics are rocks that differ from the native rocks of the area where they are found. They were carried by glaciers for long distances and then left behind when the ice melted. Glacial erratics can range in size from pebbles to boulders, but the ones that attract the most attention are the ones that are huge and oddly shaped.

Glacial erratics are cool because they tell us a lot about the past climate and geography of the earth. They also show us how powerful and creative nature can be. Some glacial erratics have become landmarks, monuments, or sacred sites for different cultures and communities.

How to Hike Pyramid Mountain and See Three Glacial Wonders

Pyramid Mountain is a county natural historic area that covers over 1,500 acres of forested hills and valleys in Morris County. It has over 15 miles of trails that offer various levels of difficulty and scenery. The area is rich in biodiversity, with many species of trees, plants, animals, and birds.

One of the most popular trails on Pyramid Mountain is the 4-mile loop trail that takes you to three of the largest and most impressive glacial erratics in NJ: Tripod Rock, Whale Head Rock, and Bear Rock. Here’s how to do it:

• Start from the visitor center parking lot and follow the blue trail (look for blue rectangle marks). Cross a wooden bridge and a power line cut. At a sign and a large pile of rocks, take the left fork of the blue trail.
• The trail becomes steep and rocky as it climbs uphill. At 0.7 miles, you’ll reach a scenic overlook sign. Follow it to see a panoramic view of the New York City skyline and the Jersey Highlands.
• Continue on the blue trail until you reach an intersection with a purple trail (look for purple triangle marks). Turn right onto the purple trail.
• The purple trail will take you to Tripod Rock, a 180-ton boulder that balances on three smaller rocks. It looks like a giant tripod or a mushroom. Tripod Rock is estimated to be over 18,000 years old. You can walk around Tripod Rock and see it from different perspectives.
• After admiring Tripod Rock, go back to the purple trail and follow it until you reach another intersection with a blue dot trail (look for blue dots). Turn right onto the blue dot trail.
• The blue dot trail will take you downhill to Whale Head Rock, another massive boulder that weighs about 160 tons. Whale Head Rock resembles the head of a whale emerging from the ground. It’s a great spot to take photos and enjoy the view of the surrounding hills.
• After seeing Whale Head Rock, continue on the blue dot trail until you reach an intersection with an orange trail (look for orange circle marks). Turn right onto the orange trail.
• The orange trail will take you to Bear Rock, which is the largest glacial erratic in the area. It measures 30 feet high and 50 feet long, and it weighs over 200 tons.  You can also find some smaller rocks nearby that look like bear cubs.
• After exploring Bear Rock, go back to the orange trail and follow it until you reach an intersection with a blue trail. Turn right onto the blue trail.
• The blue trail will take you back to the visitor center parking lot.
