Loved visiting here. - Definitely worth the trip (and that in and of itself was fun, a boat ride along the Thames). We loved all the displays, especially the ones about John Harrison and his clocks, used to measure longitude accurately. There’s a good bit of a climb up the hill to get to the observatory, but I have difficulty with hills and was able to manage it with plenty of rest stops and a slow, steady pace.

Excellent tour, excellent disability service from staff. - Excellent experience on the guided tour at the Observatory for wheelchair guest and companion. Disability aware staff member stayed with guest all the time, during parts of tour guest couldn't access the assigned staff continued the tour in another location which was just as good as main tour. Very interesting and informative tour. Credit to Paul and Mary for the excellent experience. Highly recommend for everyone and mobility restricted people.

Free expert talks - Mike D made this a great day out! - Absolutely fantastic day!!! Biggest shout out to Mike Dp the Harrison’s Clocks Expert and raconteur! The 1:00pm red ball drop, the Greenwich Meridian, but above all the H1 - H4 clocks and the Longitude Prize stories, were beautifully told, super knowledgeable, super friendly and approachable, Mike was a delight! Make sure you get there before 1:00 pm for the time signal (red ball drop), and catch Mike’s talks - you won’t regret it 😊

Awesome - This is amazing. Our British history is so much to be proud of, especially of the global significance. The views over to the Docklands are amazing. Such history British, but global.

Great place, worth a visit, definitely recommend it - This place was amazing. It's definitely worth the visit and a long hilly walk. The views are amazing, and the history behind it all.

Great one day trip - Greenwich! - Needless to say, a must visit! There's a lot to cover and you can spend an entire day. Go early to get good pictures of the Prime Meridian line. There's a ball drop event that happens at 13:00 everyday at the Observatory court. If time and space facinates you then this is an interesting place. But don't buy the tickets just to get a photo at the Prime Meridian line. Also try Jude's salt and caramel ice cream, it was yumm! Book your Planetarium tickets in advance to not miss your chance. They get sold out pretty quickly specially during the holidays. There are free visits to Queens house and National Maritime Museum, I'd recommend it. Plan one day for Greenwich and visit cutty sark, Greenwich market and try the cable car. If you are adventure freak, try Up at the O2.

Fun time at the observatory - Steep climb up to the observatory, but there is an alternative route that is more accessible if you need it. Most exciting thing was to take a pic with one foot in the eastern hemisphere and one in the west! Staff were friendly and helpful, a great time.

The Viator app does not work on tjf iPjone 12 Pro - The Viator app does not work on the iPhone 12 Pro ios 17.0.6. When the Viator app was accessed the Get Tickets button was clicked but apparently the app is not optimized for the smaller format because it would not allow the tickets to downloaded. I had to buy a second set of tickets from the box office of the Observatory. Viator owes for the first set of tickets, not to mention the frustration and embarrassment
