Natural Stone Bridge and Caves: A Walk Through Tour

This week we continue with the Exploring Locally Series by visiting the Natural Stone Bridge and Caves. The Natural Stone Bridge and Caves is a natural wonder located in the Adirondack Region of New York. The trail is a 3/4 mile loop trail that takes you past the Trout Brook, Stone Bridge, entrances to several caves, and a whirlpool and pothole.

Visitors can explore the trail on a self-guided tour or those looking for more thrill can join in on the Adventure Tour and climb and crawl through the caves and underground river.

The trail through the Natural Stone Bridge and Caves is about 3/4 of a mile long. The hike is fairly easy and do-able for hikers of all levels and children. The trail does contain over 500 rock and wooden stairs.

After exiting the gift shop, begin the trail at marker one and follow the trail to the right. Along the trail you will find markers, which will match up with a provided map and some information about each site.

The trail will first take you through a garden area, adventure park, and the disc golf course. I bypassed this section and continued on to markers #4 and 5, which overlook the Trout Brook and the Sawmill Waterfall Site.

#4: The Trout Brook: The Trout Brook is the remains of the once rushing river that crafted the Natural Stone Bridge and Caves. The river was formed by the melting of the Wisconsin Glacier. The brook is now a small, calm stream that is home to trout, turtles, and beavers.

#5 Sawmill Waterfalls Site: A water wheel once stood at the site and provided power for the early Dutch pioneers that was used to cut lumber and grind grain.

After visiting the Trout Brook and Sawmill Waterfall Site continue on down the path to Meditation Isle at marker #6.

Meditation Isle is a small island-like area that will bring you in front of the stone bridge and give you some great views. Next, continue back up the path (it is a round loop) and head to the right, which will take you over the Stone Bridge.

The Stone Bridge is the largest cave entrance in the East and leads to one of the two main cave systems within the park. Cross the bridge and pause as marker #7, Lookout Point. This will give you some great views of the brook, caves across the way, and the Stone Bridge from above.

After crossing the bridge you will come upon the Giant Slide at marker #8. The Giant Slide is a steep cave opening that when looking down will give you a view of the river flowing under the Stone Bridge.

This will take you to stop #9, The Natural Stone Bridge. The Natural Stone Bridge cave entrance is believed to be the largest in the Eastern US. The caves were mapped between 2003 and 2010. You will be able to take the stairs down and follow the stone out to the fenced area below the bridge.

Next, continue across the bridge where you will find several smaller cave entrances. Follow the stairs into the first cave, stop #10. This cave is known as Noisy Cave and is the start of the second main cave system in the area.

When you enter the cave you will quickly see why it is referred to as the Noisy Cave. The river flows through the cave and continues underground to the other areas of the park.

Next continue back along the path and you will come upon stop #11, Peter Pan’s Peephole. Peter Pan’s Peephole can be found at the bottom of a staircase. It is a small area, but will give a peek at the river flowing underground through the Noisy Cave.

Return back up the stairs and you will come up a great photo op spot, #12. You can continue past stop #12 to #13, Serenity Point. This section was closed on my visit for construction.

Next, continue along the path to stop #14, the Upper Nature Trail. This will take you along the upper path overlooking the cave systems and natural stone bridge. It will also take you to the next section of the park where you will find the natural potholes and additional cave entrances.

Along the trail you will come upon Inspiration Point, stop #15. Inspiration Point will give you some views of the cave systems while standing on top of Hemlock roots.

Next, continue on to stop #16, the Indian Maidens Kettle. Indian Maidens Kettle is one of the largest potholes in New York. It measures over 30 feet across. This area is also a great viewing spot for the entrance to Echo Cave, which connects to the Garnet Cave.

Stop #17 is next and is known as the Oyster Shell. The Oyster Shell is the exit point for the water that flows under the Natural Stone Bridge. Also in this area if you look close enough you can see the shape of George Washington’s face in the rocks.

Stop #18 is also found in this area and represents the high water mark. The high water mark represents the line when the caves can no longer contain the water levels and it spills over into the pot hole area. This tends to occur in the spring time when the ice/snow is melting.

Stop #19 is known as the pothole area. Here you will find some smaller potholes steaming with their own biosystem. You can also view the Whirlpool, the spot where the water drains from the Noisy Cave.

  1. I’m always looking for new places to explore in New York! This is the perfect adventure considering how beautiful the weather has been, and the fact that we can’t do too much exploring at the moment. I had no idea that this even existed in my own state. I can’t wait to take my family there in August! Thank you so much!

  2. We have visited natural stone bridges in many different spots. So I was interested to read about the one in the Adirondacks. A 3/4 mile loop sounds perfect in these hot days of hiking. Even with low water flow the brook looks like a great spot to spend a few minutes of quiet. Very cool that you get a look at the cave from the Giant Slide. I was amazed at how many interesting stops there were along the path. Definitely a good spot to explore. Especially with an ice cream stop when finished!

  3. This place looks so beautiful. Perfect to explore and get some good exercise while hiking amidst nature.

  4. I have been to the Adirondacks but missed out on this natural stone bridge and caves. I would love to do that short loop. The brook and the waterfalls look simply beautiful. I will definitely explore this area when I visit NY state again. 🙂

  5. This place looks so interesting! I love the look of the stone bridge and the caves 🙂

  6. This hike looks awesome! to be honest it is not my kind of thing. I prefer harder hikes, with less marked trails that are longer and force me to camp. But I see how this is an amazing hike to do with kids or older folk. It is an amazing way to bond and spend some time with loved ones.

  7. What a nice experience! I would love to see the underground river. It is good that they installed some lights so we can better appreciate it. Thank you for sharing these tips. This is helpful.

  8. So happy to see such a beautiful sight near New York to spend a day. The hike is short which would appeal to my wife. What I love is the green,the stream and the beautiful weather during your visit. Stone bridge location looked so similar to some of the sights we have seen in Himachal Pradesh of India, which is a hill state.

  9. This is something different and so close to nature. The first picture itself got me curious. The Meditation Isle itself sounds so therapeutic. The armchair travel with you to the Stonebridge location was fun. Trout Brook, Sawmill Waterfall Site, the Giant Slide, Noisy Cave to the Oyster Shell, all of it made for a good adventure.

  10. As this trail which passes through the Natural Stone Bridge and Caves is about 3/4 of a mile long and is easy for beginner hikers and children, I would go for it. Good to know that this trail does contain over 500 rock and wooden stairs and therefore it is doable activity. I loved the Meditation Isle and the Stone Bridge and this place really looks very peaceful. Also that Noisy cave is interesting with underground river gushing out. Good they illuminated with colorful lights.

  11. I am always looking for new hikes and trails in New York. I’m looking forward to checking out this recommendation! There are so many sights to check out! I bet you views are beautiful in person. But entering the cave would be a great experience! How cool is that! Thank you for sharing this! I look forward to hiking it!

  12. I have never heard of this place before and had no idea places like this existed in New york! I always think of NYC as a concrete jungle and thats about all! How interesting! the rickety bridge at marker #6 looks like a stunning view but maybe a little scary to cross ahah! Looks like a fantastic place to hike and I hope I am able to see more of this side of the city one day!
