Should You Visit the Royal Observatory Greenwich?

The Royal Observatory sits on a hill in Greenwich Park and offers a straightforward, interesting visit rather than a flashy tourist trap. Expect to spend 60-90 minutes walking through historic rooms where astronomers worked, seeing original instruments, learning how Greenwich Mean Time was established, and standing on the Prime Meridian where you can straddle the eastern and western hemispheres. The views over London from the hill are genuinely good, especially on clear days. It's educational without being dull if you have even mild interest in science, history or navigation. The planetarium shows are separate and can be added on but aren't essential for most visitors.

Best time to visit is spring or early autumn on a weekday morning to avoid the worst crowds. Summer weekends get busy with families and tour groups. Expect to pay around £15-25 per adult for standard entry including the main buildings and Meridian Line; family tickets or combined passes with the Cutty Sark or National Maritime Museum can bring the per-person cost down. The audio guide is worth getting if you like depth.

One honest tip: do the Observatory but skip the overpriced paid planetarium show unless you're really into astronomy - the free galleries and outdoor Meridian photo spot give you most of the value. Pair it with a walk through Greenwich Park and lunch in the market for a full half-day that feels balanced rather than rushed.
