Entry No. 29 — the Cleveland file — filed under: dark-sky

Observatory Park

Designated as a Silver-Tier International Dark Sky Park, this 1,100-acre preserve offers a rare escape from light pollution just 30 miles from Cleveland [1.1.8]. Visitors can explore astronomy-themed trails, planetary pods, and view the cosmos through massive research-grade telescopes.

The move: Attend a 'Nassau Nights' event to climb the ladder and peer through the park's restored 36-inch Warner & Swasey reflecting telescope, then walk the trail of interactive planetary pods under a pristine, unpolluted night sky.
