Step into the shoes of a naturalist and scientific explorer in our newly redesigned Discovery Den. Designed with current early learning research and best practices in mind, children 0-8 can immerse themselves in New Jersey environments, examine fossils, complete puzzles and read books, all focusing on nature and the outdoors. Interactive experiences throughout the Den encourages children and caregivers to explore nature and scientific concepts together through play in a positive learning environment.
The centerpiece of the update is a mural highlighting New Jersey environments that fills the inside of the newly enclosed half of the Den - an immersive experience in nature for young learners! The mural is modeled after a naturalist’s field notebook, with stunning watercolor illustrations celebrating three New Jersey environments – the Skylands, the Pine Barrens, and the shore modeled after Sandy Hook. Appropriate animals and plants for each environment fill the mural, along with prompts to encourage immersive play and exploration. Interactive components are included in the mural, with panels to uncover hidden animals and a sensory touch board. The exploration continues off the mural, with grass and water sensory tiles covering the floor and puppets and stuffed animals available. There is even a rocking boat modeled after the lifeguard boats on the shore and soft, climbable stools representing tree stumps.
New stations in the other half of the Discovery Den continue the naturalist theme. Practice your description skills at the Observation Station, complete with microscopes and fossils with magnifying glasses, with some fossils touch-friendly for all! Enjoy our new selection of books at the Reading Station, and explore the Arts & Puzzles station with new puzzles, sensory items, and coloring sheets with facts about the animals. Look for our AR ActiveFloor stationed in the Den full-time, with interactive nature-based and sensory games for all ages. To help our young visitors move through the space, there is a Junior Naturalist guide available in the Den with prompts for each of our stations and our mural.
The Discovery Den is located on Level 2 in the Written in the Rocks exhibit hall, right next to the gift shop. The Discovery Den is free to explore and is open during Museum hours.
To ensure a safe and enjoyable experience for all families, please observe the following rules:
Capacity: 15 children at a time. If the Den is full, please explore other areas of the Museum and check back later.
Safety of all families and the Museum is our top priority. Failure to follow these rules will result in visitors being requested to leave the space.

The Discovery Den is home to all of our Small Explorers programs – look for the Small Explorers logo throughout the Museum to find fun and engaging activities, carefully developed for early learners and children up to 8 years old.
