Hidden Hollow

Nestled in a two-acre dry kettle hole—a glacially formed depression common to Cape Cod—Hidden Hollow’s unique topography provides a stimulating and beautiful outdoor setting for discovery and learning. Children can climb stepping stumps, navigate log balance beams, construct forts, create nature-inspired art, build with blocks, dig in sand, experiment with water, make music, engage in sensory investigation with plants, and more. Since Hidden Hollow™ opened in August 2010 as one of New England’s first certified Nature Explore Classrooms, more than 330,000 children, teachers, and families have spent the day engaged in outdoor discovery.

The most popular feature in Heritage Museums & Gardens’ Hidden Hollow™ outdoor discovery area is the Splash area. The Splash area allows visitors the opportunity to experiment with water play to fill buckets, watering cans and other vessels to create experiments by mixing solutions, and helping to maintain the children’s planting garden.

NEW! Enhanced and Expanded Hidden Hollow™ Splash Area

This area was enhanced in the fall of 2017 thanks to the generous support of the James M. Stoneman Charitable Fund, The Dorr Foundation, and The Cape Cod Five Cents Savings Bank Charitable Foundation Trust. The NEW and EXPANDED Splash area will be open to children and families on April 14, 2018. The enhancements will provide expanded outdoor exploration activities, including:

  • a dramatic waterfall
  • a stream for hands-in water experimentation & opportunities to build dams
  • options to measure water flow
  • Spill bowls to experiment with how objects sink or float

The new features expand children’s exposure to STEM ideas as they experiment with a multitude of science concepts, including physics (flow and motion), chemistry (solutions and cohesion), biology (plant and animal life), and mathematics (measurement, equivalence, and volume).
