  • We went here after a long day of traveling but it was a nice spot! Very crowded around the line and hard to get a picture even in October. Overall very interesting. 
  • I absolutely love it here. I usually visit in the summer, but this place is lovely in the autumn. The Royal park behind it too is lovely in the fall.

  • I visited this place for the 2015 astronomy photographer of the year exhibition and absolutely loved it! educational, inspirational and enjoyable. I find the layout a little confusing but managed not to get lost which is something I seem to be adept at in museums.
  • The observatory is mainly a museum about time keeping, clock making and everything around how precise clocks and astronomers helped developing worldwide navigation before modern technology. Lots of entertainment for kids. Avoid if you're not interested in this kind of museum, you don't have kids, you're not a kid yourself and you're not thrilled about standing and taking a selfie on the Greenwich meridian. But, without paying for the ticket, you might enjoy the view of Canary Wharf from the observatory hill and a stroll in the huge park.
  • Good place to see if visiting Greenwich, London. All things Space. There a place to eat , it's free you can pay to watch a live show. After you can walk around the park and walk to the main town.
  • Always a great place to come back to. Seen it so many times, yet it's such a stunning set and scenery. You can also spend hours on ends in the park, chilling or watching other people. Or if the weather allows, the city skyline, which is breathtaking.
  • If you are fan of outer space, stars and asteroids, you will absolutely love the Royal Observatory and the Planetarium. The excibition inside along with the audio guide, will give a good taste of what is going up there, above our heads. In the outside area, you will queue to have a photo in the meridian line - the spot where time starts and ends. You can easily spend a whole day here - The Royal Observatory is just on top of the hill in front of the Greenwich Park; don't forget to take your picnic equipment!
