• Hold hands on the walls, since the path along the top is narrow and unfenced in most places
• About an hour from Lisbon by car on the A8 (exit 15), or on Rodoviária do Oeste buses that stop about 100 meters from the old town
• Park outside the walls in the signposted lots by the tourist office and the aqueduct, some of them paid

Óbidos is a hilltop town of whitewashed houses and cobbled lanes, ringed by medieval walls about 1.5 km around. Kids can walk along the top of the walls, look into the castle (now a hotel), and browse bookshops, one of them inside a church.

Summer brings the Medieval Market, with tournaments, theater and costumed performers. In December the town hosts Óbidos Vila Natal, a Christmas village with games and shows.
