Keep an eye on personal belongings
Another thing should be taken into account is to keep an eye on personal belongings. No Joke! While travelers should always keep a watch on their personal belongings such as purses and backpacks, this is especially important in touristy areas.
Don't put your handbag on the floor, especially on café patios, and waiters may remind you to put personal belongings on unoccupied chairs near you (but don't count on them to warn you). Although theft is not a huge issue in Portugal, it is not unheard of, and some tourists have reported pickpockets in the downtown area.
Before crossing the road, pay attention to the traffic situation. Do not stand too close to the curb or to moving vehicles. Pay additional attention to anyone standing close by in case they're pickpockets; if a stranger calls, verify his or her name and the reason for phoning. If you have any doubts, please contact us again. Do not trust the words of strangers. This is definitely one of the top Things to Know Before Traveling to Portugal to protect yourself in a strange country while traveling.
