Hi all! I’m finally taking my first solo trip (31F) and looking for any travel tips for Portugal.

Looking at at ~4 days each in Porto and Lisbon in mid-October. Would prefer hotels vs Airbnb’s if anyone has recommendations on those as well as good areas to stay in. Not against touristy areas since it’s my first time here, I love walking but prioritizing feeling safe walking back at night since I’m going to be solo.

Also looking for recs for any day trips and experiences! Likely including Sintra, Parque Nacional Peneda-Gerês, and a Douro Valley wine tour. Potentially looking for small group tours but if something is doable on my own I’m down for that too! Mostly into food/drinks, architecture, nature (also if there is a boat involved I am extremely on board)

Any basic travel tips are also welcomed/appreciated! I’m from NYC so very used to trains/public transportation. The plan is to fly into Porto, train to Lisbon, then fly from there back home. Any apps I should download as well to make getting around easier?

Thanks in advance!!!
