As part of the Connecticut Department of Energy and Environmental Protection (DEEP) No Child Left Inside initative, DEEP has provided the main branch public library in each city/town across Connecticut with a CT State Parks Centers and Historic Buildings Day Pass.
These passes are used to waive the admission fees at those state parks where DEEP charges an admission to enter a building or museum:
Dinosaur State Park (Rocky Hill)
Gillette Castle State Park (East Haddam)
Fort Trumbull State Park and Visitor Center (New London)
This pass waives entrance fees for the building, center, or museum for two adults and four children (12 years and under).
This CT State Parks Centers and Historic Buildings Day Pass cannot be used for camping or special events.
