Reviews

Frommer's highly recommends Clark Planetarium. Five TripAdvisors give it an average of four owl-eyes.

• There are plenty of exhibits for free that are very interesting, especially for a non-space guru. – Zifmer, TripAdvisor
• Kids of all ages can walk on a lunar scape, can be weathermen, and can find out how much they would weigh on different planets. The gift shop is also large and definitely worth a look. – ogdenmom, TripAdvisor
