A Brief History of Sintra 

Sintra’s story stretches back thousands of years, but its magic lies in why so many civilisations chose this particular spot. Nestled in the Serra de Sintra hills, the area has its own microclimate – cooler, mistier, and greener than Lisbon just 40 minutes away. This made it an ideal summer retreat long before air conditioning existed.

The Moors recognised Sintra’s strategic importance as early as the 8th century, building fortifications high on the ridges. Later, Portuguese kings and nobles transformed the town into a royal escape, filling it with palaces, hunting lodges, and extravagant estates. In the 19th century, Sintra became the heart of Portuguese Romanticism, where architecture moved towards fantasy and symbolism, and away from strict rules and conformity. 

What makes Sintra special today is this layering of history and imagination. If I had to describe Sintra in one word, it would be “whimsical” – palaces emerge unexpectedly from the forest, ruins sit beside fairytale villas, and nearly every viewpoint feels theatrical. 

When to Visit Sintra

Sintra is beautiful year-round, but the atmosphere changes with the seasons.

• Spring (April–May) brings fresh greenery and flowers, and comfortable temperatures, making it one of the best times to visit. My husband and I were there in April, and the weather was dry and sunny, with a few scattered clouds.
• Summer (June–August) is vibrant and sunny, but also extremely busy. Expect long queues, packed buses, and little breathing room at viewpoints. An early start is essential.
• Autumn (September–October) is another excellent option, with warm days, fewer crowds, and a calmer pace.
• Winter is quieter and moodier, often misty and cool. While some days are wet, the lack of crowds can make the experience feel more intimate.

Aim to visit midweek if possible, arriving early in the morning (before 9am) to beat both tour groups and fellow day-trippers from Lisbon. Make sure to bring layers with you, whatever the season. Sintra often has its own microclimate, the weather can shift quickly – fog often rolls in unexpectedly.

How to Get to Sintra from Lisbon

Getting to Sintra is straightforward and budget-friendly. The simplest option is the direct train from Rossio Station, which runs frequently and takes around 40 minutes. Once you arrive, the adventure really begins – but most major sights are spread across steep hills, so local transport is key.

• Price: Around €3-€3.50 one way for a standard adult ticket (youth, seniors, and Lisbon travel cards may reduce the cost). 
• Tickets: Sold at CP (Comboios de Portugal) ticket machines and counters; you’ll need a rechargeable Viva Viagem card to load the fare. 

Driving is possible but not recommended. Roads are narrow, parking is limited, and traffic can be frustrating.

Visiting Sintra on a Tour vs Independently

My husband and I visited Sintra without a tour guide, which is our normal travel style. We read some blogs before arriving in the town, and made sure to read the display boards at the various sites we visited. However, if you’d like a deeper understanding of Sintra’s history, I suggest joining an organised tour. 

Guided Tours of Sintra

A guided tour can be appealing if you’re short on time or prefer everything organised for you. Guided tours from Lisbon to Sintra usually include transfers to and from Lisbon, with local guides bringing the history to life with stories, legends, and context you might otherwise miss. These tours often include entrance tickets, transport between sites, and sometimes lunch, which can make them convenient and cost-effective if you want everything bundled. 

The downsides of guided tours include having limited time to wander around the sites, or linger somewhere that really captivates you. Tours often arrive at peak times with groups, which can feel crowded and rushed. 

If you really want to make the most of your time in Portugal, you can do a full-day guided trip that combines Sintra’s highlights (Pena Palace and Quinta da Regaleira) with Cabo da Roca and Cascais. Cabo da Roca is the westernmost point of mainland Europe, famous for its dramatic cliffs, and panoramic Atlantic views. Cascais is a charming seaside town about 30 km west of Lisbon, known for its sandy beaches, elegant marina, and lively historic centre.

Visiting Sintra Independently

Exploring Sintra on your own offers freedom and spontaneity. Using local buses like the 434 and 435, or walking between nearby sites, you can tailor the day to your interests. You need to do some logistical planning – checking bus routes, opening hours, and queues – but the reward is moving at your own pace. You can spend longer in places that enchant you, skip those that don’t, and adjust your timing to avoid crowds.

Travelling this way can be cheaper if you use local buses and buy tickets selectively, but costs add up if you visit multiple sites. 

The Unmissable Highlights of Sintra

Palácio da Pena (Pena Palace)

Few buildings prepare you for the first glimpse of Pena Palace. Bright reds and yellows burst through the forest canopy, and as you climb higher, the palace reveals itself like a fairytale fortress. The colours are both bold – with punches of sunflower yellow and deep red – and delicate, with touches of lavender and baby blue. 

Built in the 19th century under the direction of King Ferdinand II, Pena Palace is a bold expression of Romanticism, blending Gothic arches, Moorish details, and Renaissance and Manueline flourishes. Walking its terraces feels like stepping onto a theatrical set, with sweeping views over Sintra’s hills and, on clear days, all the way to the Atlantic.

It is very clear why Pena Palace is the defining image of Sintra, but I must admit the crowds were quite stifling. It was challenging getting photos without a line of people posing for selfies or taking photos of their families. 

Instead of trying to get photos of the palace without anyone else around, I focused more on the details, getting up close and personal with Sintra’s beautiful tiled walls, columns with swirling carved patterns, sweeping archways, and intricate carvings. The splendour of Pena Palace is certainly impressive, but for me, its true beauty lies in the details. And while it isn’t my favourite sight in Sintra, I think it is definitely worth visiting. 

Opening Hours

• Park: 09:00-19:00 (last entry 18:00)
• Palace: 09:30-18:30 (last entry ~18:00)

Ticket Prices

• Palace & Park: Adult €20, Youth (6-17) €18, Senior (65+) €18, Family (2 adults + 2 youths) €65 
• Park-only: Adult €10, Youth (6-17) €9, Senior (65+) €9, Family (2 adults + 2 children) €35

My husband and I chose the “park only” ticket, which gives you access to the palace grounds, courtyards, and terraces. We could still see a lot of the palace this way, without paying to go inside.

• Pena Palace Interior: If you want to see the inside of the palace, you need to pre-book a ticket with a specific timeslot. You can book your ticket here on the Palace’s office website. Time slots can sell out quickly, especially in peak season, so booking several days in advance is recommended. 
• You can order standard entry and fast track tickets ahead of time, which include an audio guide via the Zoomguide app (available in Portuguese, English, Spanish, and French)
• Combo tickets: There are often combined ticket options for Pena, Moorish Castle and Regaleira that can save money.

Castelo dos Mouros (Moorish Castle)

The Moorish Castle offers a completely different perspective on Sintra. These rugged ruins snake along a dramatic ridgeline high above the forest, creating one of the most striking silhouettes in the region.

Originally built around the 8th century by Muslim rulers occupying the Iberian Peninsula, the fortress served as a strategic watchtower over the Atlantic coast and northern territories. Its position alone explains its importance – from here, you can see for miles in every direction.

Before you even reach the castle walls, you’ll walk through peaceful forest paths, surrounded by greenery and birdsong. Then suddenly, the imposing stone towers appear above you. Climb up the narrow steps and you’ll emerge onto castle battlements that feel straight out of Game of Thrones. Walking the walls and staircases is exhilarating, windy and slightly exposed. From the top, you can see Pena Palace rising above the trees, the town of Sintra below, and the vast landscape stretching toward the coast.

Practical Tips for First-Time Visitors

• Go early: Pena Palace is the most popular site, and buses fill up quickly in the morning. 
• Plan your loop: Decide in advance which sites you want to prioritise, since the one-way system means you can’t easily hop back. I suggest starting early with Quinta da Regaleira or Pena Palace to avoid the heaviest crowds.
• Getting around: Use the 434 bus from the train station to reach the hilltop sites. Walking is steep and time-consuming.
• Combine routes: Many visitors take Bus 434 in the morning (for Pena & Moorish Castle) and Bus 435 in the afternoon (for Regaleira & Monserrate)
• Uber in Sintra: Uber/Bolt operate in Sintra and can be useful for uphill routes and avoiding queues for the buses.
• Book ahead: Buy tickets online in advance, especially for Pena Palace, to secure a time slot.
• Time needed: Plan at least a full day. Many sites take several hours, particularly those with large gardens.
