"What a wonderful place to visit for the whole family! Toddler play room, interactive room for all ages, demos and talks. Looks like these guys thought of it all. Very beautiful campus to walk around. Definitely go see different telescopes they have and take a look at the sun and the sun spots during the day.

Everybody who works here is super friendly and will gladly engage in a conversation about all space matters ❤️"

"I had such a great time visiting Lowell Observatory! It's a super fun and engaging place that’s perfect for all ages. The setting is absolutely beautiful, and there's a really cool mix of indoor and outdoor activities to explore. From hands-on exhibits to fascinating shows and live presentations, there’s always something going on—and it changes often, so every visit feels fresh and new.
There are plenty of shows and mini plays to choose from, which makes the experience even more dynamic. It’s very interactive and the staff are friendly and knowledgeable, which adds to the fun. I’d definitely recommend going on a clear day if possible, especially if you want to take full advantage of the stargazing opportunities.
All in all, a fantastic spot for science lovers, families, or anyone looking for a unique and inspiring experience!"

"My 9 year old daughter is obsessed with space. This place was great!! We didn't make it early enough for tickets to the outdoor planetarium which was a bummer.
We had a great time walking around the grounds at night, looking through the telescopes and playing in the play zone.
The inside exhibits are very informative. The smells are the best and worst! I feel like I can still smell one in particular weeks later. 😂
I wish there was better organization at the group of outdoor telescopes. And maybe better signage or markers between the Clark and the indoor exhibits. We still made it where we needed to go but I could see how it'd be easy to get lost or end up somewhere you don't belong.
All in all it was an amazing visit. We showed up around 8pm on a Friday night and it was definitely busy. But the skies were clear and the weather was nice.
We'll absolutely be back. Especially since Lowell participates in the Museums For All program."
