Boulders

Our climbing boulders are the best. Period.

Versatile, beautiful, and full of problems**.

These functional pieces of art:

  • are hand-sculpted, hand-painted concrete with excellent climbability. No climbing boulder feels or looks more like the real thing.
  • fit virtually anywhere: playgrounds and parks, corporate office entryways, outside a college or university recreation center, backyard of a home, or a climbing playground
  • are excellent outside or indoors
  • meet most playground height requirements for playground climbers and jungle gyms
  • do not need ropes, harnesses, or rock climbing gear
  • fill a small footprint and can be budget conscious
  • are an investment that will last into the next century and beyond.

    **A PROBLEM is a term used in bouldering. It is the path that a climber takes in order to complete the climb. Same as a route in roped climbing. Having holds already carved into the surface is just one benefit of an Eldorado Boulder.

  • Custom Boulders

    Our artists can bring your vision to life. These boulders look and climb like real rock.

    We specialize in matching rock whether it's in your backyard or an iconic destination - a rock at the base of El Capitan in Yosemite, a sandstone cliff in the Utah desert, or the volcanic rock of Devil’s Tower.
