Estoril Dos and Don'ts

go all the way up the hill to the pena castle. it's a real fairytale castle with great views of the land and ocean :) also, don't forget to eat queijadas :) a local sweet

check out the surf there. a real neckbreaking beachbreak is right in front of the restaurant at praia do guincho... meet the locals in the water, have fun but don´t get drowned! enjoy!

It's a beach! Go sit down on the sand and have some real fun.

Take a local train from Lisbon to Sintra. It's easy and very affordable.
The main attractions are the Royal Palace of Sintra, the Moorish Castle and the Palacio de Pena. Especially the last one offers architecturally outrageous experiences. :)
The easiest way to get around is to take the palace tour by bus from the Sintra railway station.
Definitely, bring a camera with you. Also, it's not a bad idea to have clothing according to the weather conditions and very good walking shoes.
