Cascais Day Trip from Lisbon: Best Things to See and Do

Cascais (kash-KYEsh) is a charming Portuguese seaside town known for its beaches, inviting waterfront, coastal walk, and laid-back atmosphere. It’s just 17 miles/27 km west of Lisbon, making Cascais a delightful day trip. Don’t expect to visit major sites. They don’t really exist here. Instead, slow down and enjoy the scenery and the beach (whether you stay dry or take a dip), the scenic walking paths, the villas built by the Portuguese elite over 100 years ago, and the inviting cafés and restaurants. Think of Cascais as a relaxing day from a busy sightseeing agenda. From Lisbon, it takes 45 minutes to get there, so you have time to savor this charming coastal spot.

Cascais has a long history of being a fishing village. Then, in the late 19th century, the Portuguese royal family built a summer residence here. Inevitably, members of the country’s nobility followed, building their own villas and gardens, putting Cascais on the map. Today, it’s a popular destination for Lisbon’s locals and tourists to visit since it’s such a short car or train ride from the capital. My husband and I spent a day there and were charmed by this inviting, well-maintained coastal community.

Enjoy the Highlights of Cascais

Slow Down at a Beach

Even if you’re not planning to swim, Cascais’ beach is worth visiting. The scenery, fishing boats, and Atlantic breezes make sunbathing and people-watching so relaxing. Other beaches are close to town.

Stroll Through Town

One of the best ways to experience Cascais is simply to wander. The pedestrian-friendly historic center is filled with colorful buildings, mosaic sidewalks, boutique shops, outdoor cafés, and squares.

The waterfront promenade offers beautiful views of both fishing boats and luxury yachts, while the lively pedestrian-only district is lined with restaurants and is a perfect place to stop for lunch — or if you linger into the evening, an early dinner — before heading back to Lisbon.

Wander further west along the coastline to view impressive sites, detailed below.

Behold Breathtaking Boca do Inferno

One of the area’s most famous natural attractions, Boca do Inferno, meaning “Hell’s Mouth,” is a dramatic cliff formation where powerful ocean waves crash into sea caves and rocky arches. The scenic coastal walk to Boca do Inferno is part of the experience, offering beautiful Atlantic views along the way. It’s 1.2 miles/2 km west of town. If you time your visit near high tide, the view will be even more impressive.

View (or Climb) the Santa Marta Lighthouse

Built in the late 1800s and long a beacon for sailors, the blue-and-white Santa Marta Lighthouse (Farol Museu de Santa Marta) is now a museum. Climb to the top for breathtaking views of the town and the sea. It is open Tuesday through Sunday from 10:00 am to 1:00 pm and 2:00 pm to 6:00 pm, and closed on Mondays.

Wander through the Museu Condes de Castro de Guimarães

Built in the early 1900s, the Museu Condes de Castro de Guimarães was a wealthy businessman’s stately waterfront home. When he went bankrupt, an affluent count bought it, then added to it and renovated it. Today, the house and gardens are a lovely place to explore. It is open Tuesday through Sunday from 10:00 am to 1:00 pm and 2:00 pm to 6:00 pm. It is closed on Mondays.

Explore the Museu de Maris (Sea Museum)

The small Museu de Maris chronicles the town’s (and country’s) seafaring past. The museum is free and open Tuesday through Sunday (often closed for lunch) and closed on Mondays.

Best Time to Visit Cascais

Spring (April through June) and early autumn (September and October) offer some of the best conditions for visiting Cascais. Temperatures are pleasant, crowds are manageable, and you’ll enjoy longer daylight hours. As expected, summer is the high season with hot weather and lots of crowds.

Whenever possible, plan your visit on a weekday. Cascais is popular with day-trippers from Lisbon, and weekends often bring significantly larger crowds.

How to Get from Lisbon to Cascais

Ride-sharing (Uber and Bolt) is a convenient door-to-door option. The more economical option is to take the direct train from Lisbon’s Cais do Sodré Station to Cascais. It’s about a 45-minute scenic ride. Bear in mind that, depending on the time of year, the train can be crowded with beachgoers. Driving to Cascais is not recommended because parking options are limited there.

If you want to combine a visit to Cascais with time in Sintra in one day, consider a guided day trip from Lisbon. Search online for the option that suits you best.

Sometimes we just need to slow down and enjoy the same pleasures locals experience. This was such a day.
