My first stop after arriving in London, and the scenery was great! 👍 I booked a ticket for 7:15 PM, but they wouldn't let us in at 7 PM, so they were quite strict about the time.
We used an elevator to go upstairs, but it wasn't anything special. I originally hoped to see both the daytime and nighttime views from 7 PM, but after waiting for ages, it still wasn't dark. Then I checked and found out that sunset was actually at 8:22 PM. Not wanting to wait that long, I went downstairs early. If you're just sightseeing, about 30 minutes is enough. There are many places selling drinks, so if you want to enjoy the view while having a drink, you can spend more time there. However, if you want to see both the daytime and nighttime views, I recommend going up after 8 PM (I went on April 30th).
