Do you want to take a dip in this Fruity Pebble Lake in Montana? If you grew up in the 1960s, 70s, or 80s, you remember Fred and Wilma Flinstone. You can probably still hear Fred yelling “Yabba Dabba Doo” and imagine him taking off in his Stone Age car.

The Post cereal brand took hold of the show’s popularity and created Cocoa Pebbles and Fruity Pebbles in the early 1970s, taking the name from Fred and Wilma’s daughter, Pebbles.

But did you know you can visit Fruity Pebble Lake? Montana is home to Glacier National Park, where you’ll find the magical Fruity Pebble Lake, properly known as Lake McDonald. Let’s learn more about these colored rocks and why you should make plans to visit this special place.

Where Is the Fruity Pebble Lake in Montana With Colored Rocks? 

Located on the west side of Glacier National Park, Lake McDonald is the largest lake in the park. It’s 10 miles long and nearly 500 ft deep and results from glacier carving.

If you walk by the water’s edge, you’ll notice a beautiful rainbow of colored pebbles, giving Lake McDonald the nickname “Fruity Pebble Lake.” Montana is home to thousands of lakes, but this one feels like a fairy tale.

Lake McDonald Lodge, influenced by Swiss architecture, offers guests the perfect location to stay and bask in the area’s beauty.

It’s close to hiking trails, boat tours, and horseback riding adventures. So if you want to be right in the middle of this stunning scenery, consider making a reservation at the lodge.

Why Are the Rocks in Lake McDonald Colored? 

A couple of factors cause the beautiful colors. The water temperature stays below 50 degrees throughout the year, limiting plankton growth.

This allows guests to see almost 30 feet below the surface. If the water temperature was warmer, too many plants and algae would grow, thus obscuring the bottom.

The second reason is due to the movement of glaciers. When glaciers chipped off pieces of mountains, the colors varied. Red rocks formed with lots of oxygen and high iron levels. Green rocks formed with less oxygen and low iron levels.

Plus, the beautiful white and blue colors of the snow and pristine waters within Glacier National Park add to the beauty. It’s not just fruity pebble-colored rocks but an entire scenery of spectacular hues.

Can I Take Rocks from Lake McDonald? 

Lake McDonald is in Glacier National Park. You’re never allowed to take anything out of a National Park. The motto is “Take nothing but photos. Leave nothing but footprints.”

When travelers start taking things like flowers or rocks, they won’t be around for future guests to enjoy. Plus, the natural landscape and ecosystems get disrupted.

The Leave No Trace principle is also highly encouraged in national parks and everywhere when enjoying the outdoors. Pick up your trash, recycle plastic bottles, stay on the trails, and clean up after pets. These principles protect these natural spaces so future generations can also enjoy them.

What Is the Best Month to Visit Lake McDonald?

Glacier National Park can see snow even into June. Peak tourist season is May through October, but the earlier you arrive and the later you stay, the higher your risk of encountering chilly weather. July and August have the most comfortable climate but the most crowds.
