Marin County’s Top-Rated Playground Builder

At CK Nature Play, we build natural playgrounds that go beyond the basic structures. We design outdoor play areas in which children can explore, move, think, and grow.

We work with schools, parks, daycares, HOAs, and community organizations throughout Marin County, CA. Our team manages the entire project, from the initial site visit and design planning to installation and final inspection. We ensure that the finished space meets your goals, budget, and community needs.

Safety is at the core of everything we build. All of our playground equipment meets ASTM and CPSC safety standards, and we use high-quality materials that can withstand outdoor conditions. Whether it's a small preschool yard or a large community park, we give each project the same level of attention and care to ensure that children can play freely and safely.

What sets CK Nature Play apart is our focus on nature-based design. We incorporate natural elements such as logs, boulders, sensory plants, and open-ended play features to encourage children to engage with everything around them. Play is how children learn, and we create environments that encourage that learning every day.

Building Marin County Playgrounds That Spark Imagination

CK Nature Play is first and foremost a construction and installation firm — a dedicated division of CK Landscape, the company Gary Cartwright founded over 40 years ago and that his son Alex has grown up in, worked in, and now carries forward.

We build structural timber elements, boulder groupings, engineered surfacing systems, water play features, outdoor learning environments, and ADA-accessible site features. We understand soils, foundations, drainage, anchoring, and durability — and we build environments that last.
