You can go to Cabo da Roca on your own any time by bus. There's one every hour from either Cascais or Sintra, so first you have to go to Sintra or Cascais (by train). All in all, it will take you at least over 2 hours just to get there without spending any time visiting Cascais or Sintra. And don't forget more than two hours to get back to Lisbon. Here's a route calculation.brewerhki wrote:Ok, as we have leave bit early and must skip sunday program. We'd really like to visit westest corner of continental Europe, Cabo da Roca. So, is there nice public transportation to there and back, if we want to visit there before sunday? And also want to go around the bay (Montijo, Vila Franca de Xira, etc), if public transportation runs smoothly? Thanks for the information and sorry to disrupt with our special request.
As to getting around the estuary, there's no good transportation to do a tour, as far as I know, but then again it wouldn't be worth it either. There are, however, very interesting spots, and maybe you can visit one of them. I would recommend taking a boat to Seixal, which is close and nice enough to get a sense of how the left bank is. The boat schedule is irregular, every 2 hours off-peak or every 20 minutes at peak hours (schedule here). Another idea would be to go to Cacilhas and have lunch there. There are plenty of good and not expensive restaurants at Cacilhas. Although Cacilhas' riverbank is not nice as Seixal's, there's much more boats taking you there (schedule).
Notice that in all schedules, "Dias úteis" means "Monday to Friday" and "Sábados" means "Saturdays".
and up. On the other hand it shouldn't be too hard to find some bank or exchange bureau clerk willing to give you
