20+ Free Things to Do and See in Boston in 2025

"For almost 60 years the Coit Observatory has offered free public stargazing with telescopes and binoculars (weather permitting) every Wednesday evening, starting around 7:30–8:30pm depending on the season — the viewing takes place outside, space is limited, and you need to reserve a spot in advance." - Matthew Kepnes

How to Visit Boston in 2025: 3, 4, & 5 Day Itineraries

"For a free astronomy experience I attend Coit Observatory's Wednesday stargazing sessions (weather permitting); it's a fun way to learn about the night sky, though space is limited and minors must be accompanied by adults, so advance reservation is recommended." - Matthew Kepnes

It can be very difficult to get tickets. Although the tickets are free, they "sell out" very quickly. It took a number of tries to get tickets and we had one week that they canceled due to clouds. They had three small telescopes set up on the roof, each pointing at a different object with volunteers to answer any questions you might have. Being in the city, the selection of objects to look at is smaller than if they were under darker skies, but it was a fun evening! Parking can be a bit of a problem in the area unless you have a BU parking sticker.

Went for Public Night at the observatory and would recommend anyone who is a cosmos nerd to go! Also, great views of the city too, especially during the summer nights.

I got free tickets here to check out the stars at the observatory. They just put 2 telescopes on the roof and some guy who has given up on himself tries to tell you fun facts about the moon and most likely prays for a clear night just to keep himself happy. The view of the city is cool, just don't expect to be wowed by the stars in the city.

Semi-Difficult to get tickets, but available on Eventbrite. Highly recommend the observatory open night though. Wonderful telescopes and introduction by faculty.

I was told to confirm the Wednesday evening viewing event 2 hours to start time. I did. Then upon arrival there was signage that the event was cancelled due to cloudy skies. Information that was posted 48mins prior to the event. After bringing my family including my four year old daughter to attend I was very disappointed. Not only did I have to let down a very excited child but I had to take the 40min drive back into our town after getting to not experience what we signed up for. I am hesitant, but may consider signing up again for the observatory, only to make up for my little ones disappointment!

Excellent view of the city in all directions, seeing the plants through the telescopes is amazing as well.

During Spring and Summer, the BU Observatory is open to the public. It's a chance to see Jupiter, Saturn, Mars, or just the Moon up close! The lines are short and it makes for a great evening out.

Great for kids and general public, but staff is volunteer and not up on latest information. Limited by Boston's light pollution and would be a good spot to encourage a campaign for better lighting solutions for that part of Boston.
