Nature Detectives Kids Club

Kids 4 to 11 years old are invited to join the Nature Detectives, an interactive and engaging way to foster children’s appreciation of nature.

Mystery Guides

Join the club by participating in self-guided tours and activities. Each Mystery Guide takes you on an exploration of a specific open space property. Kids do not need any special knowledge or equipment – just curious minds and a sense of adventure.

Each guide features:

Activities that highlight the natural surroundings and history of each location.
Map.
Four to six mysteries to solve.

Due to safety concerns, we are temporarily suspending the collection of mystery guides and distribution of prizes.

Nature Detectives Library

Want to learn about plants, weather, geology, local history or animals? Take a look at Nature Detectives, an insert for kids that is part of every issues of Images, the magazine of Boulder County Parks and Open Space.

The inserts are also great resources for grown-ups (teachers, scout leaders and parents) working with kids. Students and all curious nature-lovers can use it as a resource for papers, science projects, or just a fun way to learn.
