Caldas da Rainha is just a 20 min ride away from the house & has a lot to offer (besides driving by Obidos on the way over).
We love going to this little city to enjoy the daily market at Praça da Frutas to stock up on local fruit & vegetables. There is a lovely lady & her son who sell the best strawberries & tomatoes somewhat halfway the market place, we never miss this stop! A perfect way to also learn some Portuguese words, but even if they do not understand you, Portuguese are super friendly.
After strolling over the market, head over to the top of the market place to buy some olives or delicious granola at Loja Azeitonas Do Oeste. You cannot leave this place without strolling thru the streets & shop some local art at Sr. Jacintho or beautiful clothes at Hava Concept Store. Close of your stroll with a a coffee at Pastelaria Baia with a sandwich or a Pasteis de Nata on your way to the Parque Dom Carlos where the kids can play, hire a little boat on the lake or visit the botanical gardens!
