Nicros’ Boulders are the most realistic and fun-to-climb playground rocks available. Each Nicros Boulder has been carefully crafted from molds of real rock to capture the diversity of climbing handholds that only nature can create. This attention to detail has created a line of playground pieces that are unequaled in terms of esthetics and blending in with natural park settings.




Nicros Boulders are made from a combination of hand sculpting and molds from real rock, resulting in a stunning appearance. These playground boulders are sure to draw attention to any park.

Nicros Boulders are made using a special fiberglass mixture which results in a beautiful, realistic look and feel. The features on the playground boulders are ergonomically designed so that they fit the natural hand position in a comfortable way – not adding undue stress to tendons or joints. Since the features on Nicros’ boulder are all rounded, the hand remains in a relaxed, anatomical position while climbing. The features are also “tennis shoe friendly” so that climbers will not take an unexpected fall due to a poorly designed foot placement.



Nicros Boulders are light weight and can be easily installed in a variety of locations. Five sizes of boulders guarantee something for kids of all ages.

we chose to make our boulders out of fiberglass over common GFRC for added durability, easy maintenance, and the ability to ship without cracking. Nicros boulders have a UV resistant outer coating, no modular holds to maintain or t-nut holes to attract insects, and an anti-graffiti coating.


The designers at Nicros have over 30 years experience in rock climbing, allowing them to design a boulder that simulates movements used in climbing real rock. Keeping in mind that children were going to be the ones doing these movements, we scaled the Boulder to be climbable by kids of all ages. The features on our playground boulders are always designed with the end user in mind. The in-cut features on Nicros’ Boulders are specifically designed to aid in the removal of water preventing pooling and expediting drying time.


The molds for Nicros Boulders are designed in house and then sent to be fiber glassed. A special UV resistant outer coating is laid into the mold first and backed by a high glass content polyester resin. The parts are then assembled by standing them into place and fiber glassing them together from the inside, forming a super strong one-piece boulder. The seams are then filled from the outside and textured to form a seamless outer surface.


Nicros boulders are lighter in weight than other GFRC products, making installation seamless. All Nicros’ Boulders arrive at your site complete and ready to install. Depending on the boulder size, a fork lift or small crane will be needed to lift the boulder into place. Footings or security points can be handled a number of ways and custom options are available. All boulders are shipped with complete installation instructions.
