Because we had so many things to see in Sintra and its surroundings we got there early. We got there from Lisbon by train- which costs approx 4 euro for a return ticket. The 434 bus takes you to Pena Castle, the bus station is located about 50 meters left from the train station. The bus ticket was 5 euro per person- quite a lot considering the transportation prices in Portugal but it saves a lot of time- that would be otherwise spent climbing a steep road through the woods. We got off to Pena Castle and we decided for the combined ticket which includes entry for all 4 attractions: Pena, Moorish, Capucho's Convent and Monseratte Palace- all for 22 euro. Be sure to keep your ticked as you will definitely need it later. Pena is an exquisite piece of architecture, it looks exactly like a fairy-tale castle without being too much. From Pena we walked back down the road to the Moorish Castle which is -how many would describe it- just walls. However the views from up there are breath-taking and considering this dates back to the 9th century it is really worth seeing. We didn't want to miss Capucho's Convent so we decided to walk- it is pretty far away from the rest, and it took us a little under 2 hours to get there by foot - there is no transportation, only taxis. The convent is wonderful in every way- my favorite parts were the incredibly small monk cells and the beautiful patio with the fountain. With one last attraction on our list we decided to call a cab which took us to Monseratte through the beautiful village of Colares; the price was very affordable only 12 euro.
Needless to say that Monseratte Palace was an over-the-top experience with its luxurious gardens and its beautifully adorned interiors. From there we took another bus to get back to Sintra (don't quite remember the number)- another 3 euro each.
All four attractions are worth visiting, but you should plan a whole day for this trip, have comfortable walking shoes, take enough cash for entrance fees, souvenirs and transportation and pack a lunch box and plenty of water.
