A two-day driving route north of Lisbon: Queluz, Mafra, Ericeira and Óbidos

The shape of the route, and the car logistics

The loop runs Lisbon to Queluz to Mafra to Ericeira on day one, then the coast road north to Óbidos on day two, returning to the city on the A8 in about an hour. Total driving is 210 to 230 kilometres depending on whether you take the scenic N247 or the motorway, and no single leg is longer than 55 minutes. That is the point: this is not a road trip about distance, it is about getting out of the Lisbon basin and into a landscape of pine, dunes and walled towns that the train cannot reach in the same day.

Collect the car outside the centre if you can — airport desks and the Parque das Nações depots avoid the misery of driving out of Baixa. Hire runs €30 to €55 a day for a compact in shoulder season, more in August. Take the electronic toll transponder: the A8 north is barrier-free and cash is not an option in the fast lanes; expect €1.85 to €2.50 a day for the device plus about €7 in tolls for the whole route. Diesel and petrol sat around €1.65 to €1.85 a litre through 2025, and the whole loop needs roughly one tank.

Day one, 09:30: Queluz before the coaches

Leave Lisbon by 09:15 and you are at the Palácio Nacional de Queluz in 20 minutes on the IC19, before the Sintra-bound traffic solidifies. Entry is around €10 and the palace opens at 09:00. This is the rococo one — pink, low, French-influenced, with a mirrored throne room and formal box gardens laid out on a canal. It takes 70 minutes to do properly and is the best-value palace within 30 kilometres of the capital, largely because almost every visitor drives past it on the way to Sintra. Park in the marked bays on the square in front; free, and rarely full before 11:00.

Out by 11:00, take the A16 north and then the A21 to Mafra, roughly 35 minutes. The road climbs out of the coastal plain into windmill country and market villages, and you will pass more roundabouts than you expect — the local convention is to signal late and commit early. Fill up in Malveira if you are low, because the coast is dearer. You want to be at Mafra by 11:45, which leaves you an hour before the palace crowds peak and gets you to the church door as the light comes through the west front.

Day one, midday: Mafra and the library with the bats

The Palácio Nacional de Mafra is the largest building João V ever commissioned, a basilica-plus-convent-plus-palace complex of 1,200 rooms with a facade 220 metres long. Entry is around €12 and the self-guided route takes 90 minutes at a brisk walk. Two things justify the drive: the infirmary corridor with its cells opening onto the chapel, and the baroque library — 40,000 volumes, marble floor, and a resident colony of small bats released at night to eat the insects that would otherwise eat the bindings. The basilica itself is free, and the carillon has 92 bells across two towers.

Eat in Mafra town rather than the palace café: the restaurants behind the square do a three-course lunch with wine for €12 to €16. If you have the appetite for one more stop, the Tapada de Mafra hunting park is five minutes north — 800 hectares of walled woodland with deer and wild boar, entry about €7, and walking trails of one to three hours. Skip it if you want beach time. Leave Mafra by 15:00 for Ericeira, which is 12 kilometres and 15 minutes down the A21.

Day one, afternoon and night: Ericeira

Ericeira is a whitewashed fishing town on a cliff that happens to be a World Surfing Reserve, one of only a handful anywhere. Park in the free lots on the northern edge and walk in — the old grid is narrow, one-way and cruel to hire cars. Spend the afternoon on the clifftop path: Praia dos Pescadores below the town, then north past Ribeira d’Ilhas, where the competitions run, and Coxos, which is a right-hand reef break locals will tell you not to paddle out on unless you know exactly what you are doing. Sunset from the Furnas viewpoint is the town's real attraction.

Dinner is percebes if they are in season and you can stomach the price — €50 to €70 a kilo for goose barnacles prised off these rocks — or, far more sensibly, grilled fish by weight at €45 to €60 a kilo, meaning €18 to €25 a head. Sleep in Ericeira: the surf guesthouses and small hotels in the old town run €70 to €120 for a double outside August, the cliff-edge places with sea-facing balconies €130 to €200, and everything roughly doubles in the first three weeks of August. Book ahead for any weekend between June and September.

Day two: the coast road north to the lagoon

Leave by 09:30 on the N247 heading north, which shadows the coast through Ribamar, Santa Cruz and Praia Azul. It is 45 minutes to Santa Cruz with two stops, and it is the reason you took a car rather than a bus: sea stacks, wind-flattened scrub, and beach car parks that are empty on a Tuesday morning in May. Santa Cruz has a proper beachfront and a cliff walk of about two kilometres. Coffee there, then inland briefly to pick up the A8 north at Torres Vedras, or keep on the smaller roads if you are unhurried.

By 11:45 aim for the Lagoa de Óbidos, a shallow tidal lagoon 15 minutes west of the walled town, where the water is calm, warm-ish and full of paddleboards and small dinghies. Foz do Arelho on the south shore is the best access point, with parking near the sand and a strip of restaurants doing lunch for €14 to €20 a head. This is the swim of the trip — the open Atlantic beaches on this coast run 16 to 19 degrees and have rip currents; the lagoon is two to three degrees warmer and shallow for a hundred metres out.

Day two, afternoon and night: inside the walls at Óbidos

Óbidos is 12 minutes east of the lagoon. Park in the big lot outside the Porta da Vila — free or a couple of euros depending on the season — because the walled village bans visitor cars, and drive-in attempts end in a three-point turn in front of an audience. Arrive after 16:00 and the day-trip coaches are already leaving. Walk the full circuit of the medieval wall, which has no handrail in long stretches and a drop of eight metres in places, then down Rua Direita for the ginjinha sour-cherry liqueur served in a chocolate cup, about €1.50.

The bookshops are the surprise: one occupies a deconsecrated church, another a former market hall, part of the town's literary festival identity. Dinner inside the walls is €20 to €30 a head. For the night, the landmark option is the pousada built into the castle keep itself, at roughly €180 to €280 for a double — genuinely worth it once, and the only way to have the village to yourself after 19:00. Otherwise the guesthouses inside the walls run €70 to €120, and the country hotels on the surrounding hills €90 to €150 with parking included.

Getting home, extensions, and what to skip

Óbidos to Lisbon is 85 kilometres and 60 to 70 minutes on the A8, with about €6 in tolls. Leave by 10:30 on day three and you can drop the car and still have most of the day. If you have a third night, the obvious extension is 30 minutes further north to Nazaré for the winter big-wave canyon and the funicular up to Sítio, or Peniche and a boat to the Berlengas islands from May to September at €25 to €30 return. Both add a day rather than an afternoon; do not try to fold them into day two.

What to skip: the Buddha Eden garden near Bombarral, which is a 30-minute detour to a private sculpture park that photographs better than it visits; and any attempt to add Sintra to this loop, because Sintra needs its own day and its own parking strategy and will wreck the timing. Also skip driving into Ericeira or Óbidos centre — both are walkable in ten minutes from free parking, and the fines for the restricted zones are real. Two nights, four towns, one lagoon: that is the honest capacity of this route.
