Monkey Rock is a popular swimming place for Idahoans of all ages, but most commonly, BYU-I college students are its visitors. The water temperature is usually cool, but it is welcome during the hot summer months. The waterfall is not only a fun feature but a beautiful backdrop for engagement photos. 

The name “Monkey Rock” comes from all the crazy people who jump off it into the pool below. Although it is not very high up, many people have gotten hurt, so use caution. Throughout the year, the water level alternates, so use common sense when jumping off the rocks.

When the water level is low, many people use monkey rock as a slide.  If all else fails, this is a great spot for swimming.

It is about 20 minutes from Rexburg and is also a great spot for bonfires!

*Use caution and good judgment when jumping off the falls or going down the slide.  There are large rocks underneath the surface of the water. There is also a concrete water canal upstream which angles down under the bridge. Underwater currents can cause you to get stuck under the bridge.

Things to Bring:

  • Swim Suit/Board Shorts
  • Water Shoes
  • Towel
  • Sun Glasses
  • Camera
  • Warm Clothes for after Jumping
  • Life Jacket
  • First Aid Kit
  • Cell Phone

    Monkey Rock is located on private property and the falls are located on a privately owned canal. This is not a public river. You need permission to go there.

  • Abby says:

    Many people have died there in the water. This includes the canal above the falls and those that jump from the bridge and float past not knowing the dangers. There is also many many people who split their faces open by landing on the invisible rocks and boulders below. Swim with caution!!!

  • Margie Harris says:

    This is misleading and makes Monkey Rock sound like a safe, carefree place for students to swim. It is not. I’ve now seen three BYUI students lose their lives there. It is not like Rigby lake, Egin Lake, or Warm River that are safe. You are giving students dangerous information that could cost them their lives too.
