Beautiful but long lines if you don’t go very early before it opens. Great to see if you get there early. We did and enjoyed it and got to the Belem pastelria early too. All worked out. Didn’t wait in the line for the tower. Loved getting out on the river and hearing the history.

It was a great experience. Easy to purchase ticket and access on day of entry on Get-Your-Guide app. Cost of entry to monastery was very reasonable. Our entry was for 9:30am. We arrived at 9am and glad we did because there was already a long line for entry, so get there early! In hindsight, we should have arrived super duper early, and spent at least 1 hour directly across the street at the gardens. Then queque up f9r the monastery. Important note: the ticket to the monastery DOES NOT give you entry to the cathedral. That's a separate ticket and a whole other line to stand in. It's a totally separate day trip.

Stunning monastery cloister that highlights Baroque architecture and the opulence that was Portugal due to the spice trade. Great opportunity for stunning pictures and history. There are two levels, each with their own perspective. Highly recommend for anyone in Lisbon/Belem.
