Where is Natural Stone Bridge and Caves Park?


Natural Stone Bridge & Caves is located in Pottersville, in the Adirondack Region of New York.

It’s a perfect day trip if you’re visiting the Lake George area, and it’s only 70 minutes away from Lake Placid.

As we planned our camping trip to Lake George my husband said to me, “would you like to visit another cave?”

Well, you know me and caves! Of course, I said, “Yes”!

We decided to camp at Adirondack Camping Village, which was just a few minutes north of Lake George, and an easy drive along Rt 9 to Natural Stone Bridge and Caves.

How the Natural Stone Bridge and Caves Was Formed

At the end of the last ice age, The Wisconsin Glacier melted into a roaring river that formed the Natural Stone Bridge and Caves.

Today, Trout Brook is a tranquil waterway filled with many rainbow trout, snapping turtles, and the occasional beavers.

Visit The Rock Shop

Our first stop was at the Rock Shop where we admired the beautiful gemstones the owners have been collecting for over 40 years.

Amethysist and gems at Natural Stone Bridge & Caves

The park has the largest collection of Amethyst cathedrals, Mexican Geodes, Large Quartz Crystals, and hundreds of other rock and mineral specimens are available to view or to purchase.

From there we walked to the petrified Wood Display. Of course, along the way, we found this statue which was a great place for a photo op!

We wound our way to Trout Brook and down the walkway to the Sawmill Waterfall Site.

Early Dutch pioneers used the waterfalls of trout Brook for water wheel power to cut lumber and grind grain. (1750-1910)

Going over the bridge to Meditation Isle provides a spectacular view of the Natural Stone Bridge.

Beatiful View of Natural Stone Bridge

The paths are clearly marked – but you will have to climb some steep stairs along the way. Kids loved it!

Noisy Cave Falls

As you enter the cave, the park has added lights and positioned them so you can see the pretty rock formations.

Water from Trout Brook creates this waterfall inside the cave. It then flows out underground and rejoins Trout Brook

While there is a lot of walking and climbing stairs, just take your time throughout the park so that you don’t miss anything!

You will be required to not only climb stairs, but also be able to duck your head to walk through some of the natural stone which is why the park requires you to wear safe rubber-soled shoes.

Thoughts On Natural Stone Bridge and Caves

The park does not allow dogs in the park so be sure to make plans ahead of time if you travel with your pet as we do.

We have been to many caves throughout the country but each is special and unique and we always take the time to explore them if they are near where we are camping!

If you love caves and chasms then you should definitely add Natural Stone Bridge and Caves to your Lake George itinerary!
