I’m a big fan of Mike & Anne Howard. These two young people have a fabulous life plan which involves full-time economic travel. The link here shows their trip to Sintra, Portugal. I’ve been there and it’s a jewel of a spot, quite magical actually. It’s a short train away from the center of Lisbon. Here is their website to get help for your adventures. https://www.honeytrek.com/sintra-portugal-1000-years-history-1-day/
