Nature centres keep shorter hours than the parks around them and several close outside the season. The official page for each is where the current hours live.
Drive times are estimated from straight-line distance ×1.15 for road routing, at a speed that rises with distance from 40 mph on local roads to 65 mph on the interstate. Fees are not in the state dataset — every entry links to its official page.
This page covers the state park nature centres, because that is the part we can source from the state directly. Museums, pools and indoor play centres are being checked venue by venue and will be added rather than guessed at.
