One Day in Cascais: Luna House’s Favourite Coastal Walk

Coastal walking route from Luna House to Boca do Inferno and Casa da Guia in Cascais

When guests ask us how to spend one day in Cascais, this is the route we love to recommend.

It is not simply a list of attractions. It is a day shaped by the ocean: fishing boats in Cascais Bay, quiet museum gardens, the blue-and-white Santa Marta Lighthouse, the sound of Atlantic waves at Boca do Inferno, a relaxed lunch at Casa da Guia and, if the timing is right, an unforgettable sunset.

The walk starts at Luna House, passes through the historic centre of Cascais and follows the coastline west. You can make it a gentle half-day walk or take your time and turn it into a full day of museums, coffee, food and sea views.

Before you leave Luna House

Wear comfortable shoes, bring water and take a light layer—the Atlantic breeze can arrive even on a warm day. Sunscreen is essential in summer.

If you are staying with us, speak to the Luna House team before leaving. Guests who pay the Cascais tourist tax may be eligible for a complimentary Turismo de Cascais / Museum Quarter voucher. The participating museums and conditions can change, so ask us for the current voucher and confirm how long it remains valid once activated.

Luna tip: If you want to visit several museums, start earlier and check the opening hours first. Many cultural spaces in Cascais close on Mondays, and access to the Santa Marta lighthouse tower may depend on the schedule and weather.

1. Walk from Luna House to Cascais Bay

Leave Luna House and walk towards Cascais train station and the historic centre. Soon, the streets open onto the sea at Praia dos Pescadores, also known as Praia do Peixe, beside Hotel Baía.

This small beach is one of the most characteristic views of Cascais. Traditional fishing boats rest in the bay while the old town rises behind them. Pause here for your first photograph and take in the easy rhythm of the town before continuing along the waterfront.

2. Explore the Cidadela and Cascais Marina

Continue towards the Cidadela de Cascais, the fortified complex overlooking the marina. Its history reflects Cascais’s strategic position at the entrance to the Tagus and its later transformation into a royal summer destination.

Walk around the fortress walls, courtyards and marina, or visit one of the cultural spaces within the complex if it is open. The Palácio da Cidadela and its exhibition gallery form part of Cascais’s Museum Quarter; palace visits may require a guided tour or advance booking.

From here, you can choose between two lovely versions of the route:

  • Continue beside the marina towards Santa Marta.
  • Detour through Parque Marechal Carmona and rejoin the coast near the Museu Condes de Castro Guimarães.

There is no wrong choice. We often suggest taking the marina route on the way out and saving the park for the return journey.

3. Cross the bridge beside Parque Marechal Carmona

Near the entrance to Parque Marechal Carmona and the Museu Condes de Castro Guimarães, a small stone bridge frames one of our favourite views in Cascais. From this area, you can see the marina, the water and Santa Marta Lighthouse beyond.

The museum itself occupies a romantic revivalist palace commissioned in the late nineteenth century. Its tower balcony offers a wide view over Cascais when access and weather permit. Even if you do not enter, the architecture and setting are worth seeing.

4. Climb Santa Marta Lighthouse—and stop for coffee

The blue-and-white Farol Museu de Santa Marta is one of Cascais’s most photogenic landmarks. Built on the site of the old Santa Marta Fort, the working lighthouse and museum tell the story of Portuguese lighthouses and the people who maintained them.

If the tower is open, climb to the top. The view over Cascais Bay, the marina and the Atlantic is genuinely worth the steps. Entry may be included in the guest voucher available through Luna House; please confirm current access before your visit.

Beside the lighthouse is Casa de Santa Maria, another cultural stop you can add if time allows.

After the climb, pause at Lusophonica, near the lighthouse and marina. We love its relaxed atmosphere, good coffee and ocean-facing setting. Music is an important part of its identity, and you may find a DJ set or live performance on the programme. It is an ideal place to slow down before the wilder part of the coast.

5. Follow the sea to Boca do Inferno

From Santa Marta, continue west along the coastal path until you reach Boca do Inferno, or “Hell’s Mouth.”

This dramatic rock formation was shaped by the relentless movement of the Atlantic. The sea eroded a coastal cave, and the partial collapse of its roof created the open chasm and natural arch visible today. During rough seas and higher tides, waves surge into the rock formation with a deep roar—the sound that helped give the place its name.

Boca do Inferno also holds a small place in cinema history. In 1896, British filmmaker Henry Short recorded the waves here in the very early film A Sea Cave Near Lisbon. You may hear that a James Bond film was shot at Boca do Inferno, but that is a local travel myth; Bond’s Cascais connections are associated with other nearby locations.

Take time to enjoy the view safely from the marked areas. Depending on the day, you may hear a musician playing nearby and see local fishers working from the rocks below. Never climb beyond the barriers—the cliffs can be slippery, and Atlantic waves are unpredictable.

If you would like another break, there are cafés and ice cream nearby. For a special seafood meal, Mar do Inferno is a long-established

6. Continue to Casa da Guia

The walk from Boca do Inferno to Casa da Guia takes roughly another 15–20 minutes at an easy pace. This stretch is one of the most beautiful parts of the route: open Atlantic views, dramatic cliffs and plenty of places to stop for photographs.

Casa da Guia occupies a nineteenth-century property surrounded by gardens at the edge of the cliffs. Today, it brings together restaurants, cafés, small shops and terraces with panoramic ocean views. Depending on the season and day, you may also find local makers selling crafts and gifts.

This is where we recommend stopping for lunch, a snack or an early dinner.

Luna House’s favourite food stops at Casa da Guia

Sandocas
Close to the entrance, Sandocas is a small local spot we love recommending. Its generously filled sandwiches feature slow-cooked meat, including pulled beef and pork. Ask whether the loyalty card is currently available if you expect to return.

A refreshing açaí bowl
Açaí is a small, dark-purple fruit from the açaí palm, native to the Amazon region. In Brazil, its frozen pulp is commonly blended into a thick, cold bowl or smoothie, often served with fruit and granola. It is refreshing after a sunny coastal walk. Check the Casa da Guia directory on arrival for the current açaí kiosk or café.

Palaphita Cascais
For a longer meal or sunset drink, Palaphita is an eco-lounge inspired by its Brazilian and Amazonian roots. Its wood, greenery and open-air atmosphere make it feel immersed in nature, while its terraces look towards the ocean. Check its programme if you are interested in music or special events, and reserve ahead at busy times.

7. Stay for an Atlantic sunset

Both Boca do Inferno and Casa da Guia are beautiful at sunset. Casa da Guia is usually the more comfortable place to settle in with a drink or meal, while Boca do Inferno feels wilder and more dramatic.

Check the sunset time before leaving Luna House and plan to arrive at your chosen viewpoint at least 30 minutes earlier. The light begins changing well before the sun reaches the horizon, and the soft colours after sunset can be just as beautiful.

Below Casa da Guia, paths lead towards the cliff and ocean-level activity areas, including a climbing school. Only use official paths and book climbing activities with a qualified operator—this coast is spectacular, but it demands respect.

8. Return through Parque Marechal Carmona

After sunset, the easiest option is to take a taxi or ride-hailing car back to Luna House. If there is still daylight and you feel like walking, retrace the coastal route.

If you visited the Cidadela on the way out, make your return different by walking through Parque Marechal Carmona before it closes. Cascais’s much-loved park combines shaded paths, lawns, gardens and ponds. Peacocks, chickens, ducks and turtles are part of its special character, making it a favourite with both local families and visitors.

Inside the park, you can also visit the Museu Condes de Castro Guimarães, a storybook-like palace containing art, furniture, Indo-Portuguese pieces and historic collections. The park’s romantic atmosphere makes it a peaceful final chapter to the day.

Suggested plan at a glance

  • Morning: Breakfast at Luna House, walk to Cascais Bay and explore the Cidadela.
  • Late morning: Visit Santa Marta Lighthouse and stop for coffee near the marina.
  • Early afternoon: Walk to Boca do Inferno and enjoy the viewpoint.
  • Lunch or afternoon snack: Continue to Casa da Guia for Sandocas, açaí or a relaxed meal at Palaphita.
  • Evening: Watch the sunset, then walk back or take a taxi to Luna House.

Allow around four to six hours for the outing, or longer if you visit museums and sit down for a full meal. The route is mostly straightforward, but it is a substantial walk when completed in both directions.

Make Luna House your base in Cascais

One of the reasons we love living and working in Cascais is that days like this do not require a car or a complicated itinerary. From Luna House, you can walk from the calm streets near our home to beaches, historic buildings, museums, gardens and the open Atlantic—all in one day.

Luna House is a welcoming bed and breakfast and coworking space created for travellers who want more than a room. In summer, it is a peaceful base for a weekend or holiday in Cascais. During our winter coliving season, it becomes a home for remote workers who want to combine productive days with ocean walks, local life and a supportive community.

Stay with us, enjoy breakfast before you set out, ask our team for personal recommendations and return at the end of the day to the garden, pool and relaxed atmosphere of Luna House.
