Small tower, one narrow spiral staircase, traffic-light entry system. The queue outside is long and the queue inside is worse. Worth booking; not always worth doing.
THE BIG QUESTION
We compared both, factor by factor.
Go on your own. There is not enough tower here to justify a guide, and the guided Belém walks spend most of their time outside it. Buy the skip-the-line entry, go at opening, and give the twenty minutes you save to the pastelaria instead.

Thirty to ninety minutes in season without a pre-booked ticket. Capacity inside is capped at around 150 people, so the door only opens as fast as people leave.
Yes, and that is exactly the queue you are trying to avoid. Same price online, and the timed slot means you turn up when you say you will.
