The historic centre of Sintra lies within the hills of the Serra de Sintra and a day trip here will involve a lot of walking up or down hills. While you can minimise the amount of climbing required, expect significantly more hill walking than you would find in Lisbon.

Insight: If you enjoy hiking then Sintra is the perfect destination for you, with many tranquil routes through the lush forests. Some of the best routes are detailed at the end of this guide.

If concerns about Sintra's hills brought you to this guide, be aware that there are many steep climbs, and the gradients are substantial. For many visitors, joining an organised tour proves the most comfortable way to explore the town's attractions.

About the only flat route is from the train station to the historic centre and the Palácio Nacional de Sintra. This 1km walk is flat and follows the Volta do Duche road, which has two wide footpaths. However, the real hill challenges begin when visiting other attractions, particularly the two most popular sites: the Palácio da Pena and the Castelo dos Mouros.

Both these attractions are situated high above the historic centre, and the only realistic way to reach them is by the tourist bus (service 434) or taking a taxi/Uber/Bolt/tuk-tuk. It is not advisable to walk from the train station up to these sights, there is a footpath, the Caminho de Santa Maria, but it is very steep and particularly gruelling during summer temperatures.

The Palácio da Pena
The Palácio da Pena is Sintra's most famous sight, but it also involves some of the most demanding hills. The main drop-off point for all tourist transport (including the 434 bus and Ubers) is at the main ticket entrance, but this is not the palace itself. From the entrance gates, visitors face a steep 10-15 minute uphill walk on a paved ramp just to reach the red and yellow terraces.

There is a short, optional bus service for this internal journey, but it requires an additional ticket (€3.50) and often has long queues during peak season.

Inside the wider palace grounds (Parque da Pena), you'll find yourself wandering through a thick forest on winding, hilly paths. This was an intentional 19th-century Romanticist design, creating a "maze-like" experience, but it means that exploring the park also involves navigating uneven terrain.

The Castelo dos Mouros
Of all of Sintra's sights, the Castelo dos Mouros is arguably the most physically demanding to explore. The main experience is climbing the ancient battlements and watchtowers, which involves navigating numerous stone steps and uneven surfaces, often without handrails.

The high stone walls snake across the mountain ridge, and walking the full perimeter requires significant effort. The castle's highest point, the Torre Real (Royal Tower), is a favourite for its panoramic views, but it requires a challenging ascent of 220 steps along the ramparts.

Given these physical demands, the fortress is best suited to visitors with good mobility and fitness levels.

The Quinta da Regaleira
The Quinta da Regaleira is conveniently located within walking distance of Sintra's historic centre. The route is relatively flat, making it accessible by foot, and most visitors will not need a Uber or the 435 bus service.

While the estate is easier to reach than the hilltop palaces, its famous gardens present their own challenges. The grounds are spread across a sloping terrain, with a maze of winding gravel paths, hidden steps, and grottoes. Most visitors want to experience the famous Poço Iniciático (Initiation Well), which involves descending a significant spiral staircase deep underground. This route often continues through a network of dark, uneven tunnels.

Palácio de Monserrate
The other notable palace, Palácio de Monserrate, sits about 3.5 km from the historic centre. Getting there requires either the 435 tourist bus or an Uber/Bolt, as the road winds through steep terrain. Once you arrive, the palace's magnificent exotic gardens are comparatively flat and much easier to explore than the hilly grounds of Pena.

The town centre offers numerous charming cafés and restaurants perfect for regular breaks during your exploration. The traditional Portuguese cobblestone pavements, while picturesque, require careful navigation - they become treacherous in wet weather and are unsuitable for high heels or thin-soled footwear. Regardless of your chosen mode of transport between attractions, robust walking shoes are essential for comfortable sightseeing.

For those with mobility concerns or who prefer to avoid hills, we suggest:
• Base yourself in the historic centre
• Use the 434 bus circuit for the main attractions
• Visit early morning or late afternoon to avoid the strongest sun
• Allow plenty of time between sights to rest
• Carry water, especially in summer months when temperatures can reach 35°C
• Consider splitting your visit over two days

The town has several steep side streets that can provide shortcuts, but these aren't recommended unless you're confident with hills. Many have handrails, but the steps can be worn and uneven.

Rainfall transforms Sintra's steep cobblestone streets into particularly challenging terrain. We strongly advise against visiting during wet weather, particularly in winter months. If planning a trip to Sintra in the winter, always visit Sintra on the driest day, and it is best to have flexible plans.

The 434 Tourist Bus

For visitors planning to explore the main attractions, the 434 tourist bus service is invaluable. The 3km walk from the historic centre up to the Palácio da Pena is along a very steep hill and is not suitable for most visitors, especially in the heat of summer.

The bus runs in a one-way loop that connects the train station to the hilltop sights of the Palácio da Pena and Castelo dos Mouros, before returning to the historic centre (Sintra Vila) and then back to the station.

A 24-hour ticket for the 434 tourist bus costs €13.50. During the high season, buses depart from the train station approximately every 15 minutes.

It is important to be prepared for the journey. The 434 bus becomes extremely crowded, and you will likely have to stand. The journey from the station to the Pena Palace is surprisingly long, taking at least 30 minutes, and can be over 40 minutes in peak season. This is because the bus must use a narrow, one-way ring road that gets clogged with tourist traffic.

Important: Taking a taxi, Uber, or tuk-tuk up the hill will not be any faster, as they are stuck in the same traffic on the same road. Drivers may even decline the fare due to the traffic.

Despite these minor issues, the 434 bus remains the best and most practical way to travel from the train station up to the Palácio da Pena.

Santa Maria Trail (Caminho de Santa Maria)
The Santa Maria Trail stretches 2 km from Sintra's historic centre up to the Castelo dos Mouros, and can continue to the Palácio da Pena. This challenging route follows ancient cobblestone paths through dense forest and craggy rocky outcrops.

The trail begins from the Palácio Nacional de Sintra, but most visitors pick it up from the top of the Parque da Liberdade. From the Igreja de Santa Maria, it rises steeply through a series of historic stone steps and winding paths.

The ascent typically takes between 45-60 minutes, though many walkers require longer due to the consistently steep gradient. During summer months, the trail becomes particularly demanding, with temperatures often rising above 30°C by mid-morning. The dense tree canopy provides some shelter, but proper preparation is essential. Early morning starts are strongly recommended to avoid the heat. The path can become treacherous after rainfall, as the historic cobblestones turn slippery.

The reverse of the route is a pleasant way to return to Sintra after exploring the Castelo dos Mouros, and avoids the hassle of catching the 434 bus.

Capuchos Monastery Trail
The Capuchos Monastery Trail extends 7 km from Sintra town to the Convento dos Capuchos. This moderate to challenging route passes through some of the region's most pristine native woodland, offering a genuine glimpse into the natural environment that has shaped Sintra's character for centuries.

The route follows the N375 out of Sintra to the Palácio de Monserrate (approximately 3 km) and then heads south along gravel paths to the Convento dos Capuchos, passing the Lagoa dos Mosqueiros lake.

The destination, Convento dos Capuchos, stands as one of Sintra's most unique monuments. This austere monastery, with its cells lined with cork for insulation, provides a stark contrast to the opulent palaces elsewhere in the region. The trail follows historic paths used by monks, passing natural springs and ancient stone markers. Walking time averages 3-4 hours depending on fitness levels and stopping frequency. The return journey can be made via the same route or by taking public transport from near the monastery.

A shorter version is possible by catching the 435 bus to the Palácio de Monserrate.

Cruz Alta Circuit
The Cruz Alta Circuit is a shorter route within the grounds of the Palácio da Pena. This 4.5 km circular walk begins from the palace and passes through the highest sections of Pena Park. This moderate difficulty trail circles the summit of Serra de Sintra, offering spectacular views across to Lisbon and the Atlantic coastline.

The circuit's highlight is the Cruz Alta monument itself, standing at 529 m above sea level. This stone cross marks Sintra's highest point and provides a natural rest stop with panoramic views. The trail surface alternates between well-maintained gravel paths and sections of original stone paving. While the route includes some elevation changes, these are generally gentle compared to other Sintra trails. The entire circuit typically takes 1-1.5 hours, allowing time for sightseeing and rest stops.
