Worth it, but budget at least a full day or more during high tourist season. Its a full castle/villiage compound complete with moat, not just a tower. We had to skip the crown jewels because of the 3 hour line. Some stuff is a little cheesy, but there's no denying the history here. The White tower is awesome. We also chatted with a 'beefeater' and learned some really cool info you'd never find in a guide, like what it's like to live there and what the ravens are like in person (apparently they are not happy birds by nature).
