I think most cruise ship visitors get advice to take Tram 28, go to Belem, visit the Discoveries monument, Jeronimos monastery and maybe the Coach museum. I find that walking in Lisbon is easy; start at Commerce plaza, walk Rua do Ouro to Restauradores, then keep walking along Avenida da Liberdade. If you want, you can take the Metro back.

There is a lot of information on www.cruisecritic.com on the Ports of Call / Europe / Other Mediterranean Ports forum.

The best thing in Lisboa is the Gulbenkian Museum.

This, in my opinion, is one of the best small museums in the world with a knock-your-socks-off collection.

It is easy to take the Metro from Restaurdoes to a stop near the museum and walk up the street a few blocks to the main entrance.

If you don't like museums, then I suggest you walk up the hill towards the Se and explore Alfama.

Belem is the only section of the city that I would even bother with. The royal coaches museum is quite interesting, and there is a wonderful bakery just up the street. Plus, you'll walk by the presidential palace.

I'd say your priorities for sights should be
1) the Castle, which gives you an amazing overview of town and river (the 28 tram - watch the pickpockets - will take you most of the way there) plus a wander through the old medieval neighbourhood down the hill (Alfama).
2) Belém with the truly amazing Jeronimos monastery and the Tower of Belem (a little further away but also not to be missed), the famous pastries, and also the coach museum, if that's your scene (not mine, I'm afraid).
If you prefer to spend you time in a museum I would recommend the Gulbenkian if you like hoovering up ancient, Oriental and western European art; if you want something with a more LOCAL flavour you are better off going the Museu de Art Antiga, which gives you a sense of Portuguese history as well as art.
Yes, you could walk through the centre from Praça de Comercio to Avenida da Liberdade but the main impression that would leave you with is one of traffic !

I believe this ship has sailed. Original post is over a year old. I think it was probably topped by an advertiser, whose post has been removed.
