We knew we had to visit Greenwich while on vacation in London and I hope that you put that on your To Do List for your upcoming vacation! Plan on going on a beautiful day since the views from the Observatory are spectacular. However the hike up the hill to the Observatory is a challenge both for the elderly and families pushing their children with strollers. There is apparently a longer less arduous path to take but going up the path is paved but challenging. However once you get there there is much to see and experience including being able to stand on both sides of the Prime Meridian! There’s the planetarium and great exhibits. And there is also a wonderful cafe run by Benugo where we had a wonderful lunch.
