I see there are several train options for travel from Lisbon to Sintra, Porto and even Guiniaraes. Any suggestions of means of travel when visiting these areas from Lisbon?.
When searching there are suburban rail services called Rail Ninja and Omio and what appears to be the main company Comboios de Portugal. Curious if we should stick with Comboios as we want both the fastest and what I read was AP trains.
Thanks.
