Hi Deborah,
There are many Facebook groups that pertain to Portugal like Americans & Friends PT, Expats Portugal, Silver Coast Our Home and many more. Reach out to expats who live in those areas to find out when their meetups are or to meet with individuals one on one to chat. The first group mentioned is based in Cascais near Lisbon so they can be of help.
Happy Travels,
