The cultural landscape of Sintra is listed as a UNESCO Heritage Site and for good reason. Sintra is the Portugal I imagined and came to see. The beauty, the charm, the history, nature – the list goes on. Sintra is magical. My biggest regret we should have visited earlier and stayed longer. Plan to spend days in Sintra. In the very very least, at least, two full days, but I would go as far to recommend five days.
