Pyramid Mountain Natural Historic area in Montville Twp. offers fun and educational birthday parties for children 4 and older.

Choose from an array of themed parties to create a memorable event. An experienced naturalist leads your party in an hour-long indoor/outdoor program. Options are available for your child’s party:

Seasonal Nature Walk: Kids enjoy walking with a naturalist who points out the wonders of nature in a variety of habitats.

Nature Scavenger Hunt: Adventurous children work in teams to search out the “treasures on the trails” during an educational nature walk.

Nature Detectives: Who’s been roaming the trails? Party guests solve the mystery as they search for animal signs, homes, sounds, and other clues left behind by our wild residents.

Bird Brained: Your party guests learn what life is like as a bird. Can they call a mate or keep up with a hungry nest of chicks? They’ll find out through fun games, activities and a walk.

Creepy Crawly Critters: Learn all about these tiny creatures by capturing, examining, and releasing real specimens. Your guests leave with a newfound respect for these amazing critters!

Lenape Life: (For ages 8 and older, only!) If your child is fascinated by Native American life, this party is the perfect choice. The children try their hands at making rope, play real Native American games, visit a wigwam (only at the GSOEC) and more!
