There are direct flights to Porto, or you can easily transfer from Lisbon/ The Azores. If you are planning on exploring Lisbon beforehand, there is also a train (takes 2.5 hours).
While we adore your little ones, we unfortunately can't include them in our weekend events.
Porto is a city so you can easily walk it or grab an uber. We recommend bringing sneakers, Porto has alot of hills!
Porto in the summer can get up to 85-90 degrees, but can cool down at night, so we would recommend bringing a wrap/sweater/sweatshirt.
