7 Hidden Gems Along Portugal's Silver Coast A Two-Week Journey from Nazaré to Aveiro - São Martinho do Porto Bay A Natural Swimming Pool with Year Round 70-Degree Water





São Martinho do Porto Bay is a remarkable natural wonder, a sheltered cove that maintains a remarkably consistent water temperature of around 70 degrees Fahrenheit throughout the year. Located on Portugal's Silver Coast, this bay's unique, shell-like shape creates a naturally protected haven, often cited as one of the safest swimming spots not just on the Silver Coast, but on the entire Atlantic coast of Portugal. The calm waters and soft, white sands attract families seeking a tranquil getaway.

While its popularity has been growing, São Martinho do Porto still retains an air of authenticity, a testament to its history as a former fishing village intertwined with the legacy of the nearby Alcobaça Monastery, a UNESCO World Heritage site. Beyond swimming and relaxing, the area offers opportunities for exploration—walking trails wind around the bay, ideal for quiet strolls or enjoying a sunset picnic with spectacular views. If you are seeking an authentic Portuguese coastal experience, a blend of natural beauty and local culture, away from the more touristy spots, São Martinho do Porto is a truly hidden gem.

São Martinho do Porto Bay, nestled within the Leiria district on Portugal's Silver Coast, presents a compelling natural phenomenon.

7 Hidden Gems Along Portugal's Silver Coast A Two-Week Journey from Nazaré to Aveiro - Praia da Tocha Beach and Its Original Wooden Fishing Houses from 1945





7 Hidden Gems Along Portugal’s Silver Coast A Two-Week Journey from Nazaré to Aveiro

Praia da Tocha, situated on Portugal's Silver Coast, offers a charming blend of natural beauty and a strong sense of local heritage. Its most distinctive feature is the collection of original wooden fishing houses, known as "Palheiros," built in 1945. These structures, which are a testament to the area's fishing past, provide a unique backdrop to a beach that spans about 12 to 15 kilometers of golden sand.

While Praia da Tocha has grown in popularity and now offers facilities like an aquapark, it retains a strong connection to its fishing roots. Local fishermen continue to practice the traditional "xvega" fishing method, a testament to the area's history and a fascinating aspect for visitors to observe. The beach itself, with its wide expanse of sand and consistent waves, has become a haven for various water sports including surfing and bodyboarding.

The village of Praia da Tocha retains a relaxed atmosphere, with an emphasis on community and family values. This, combined with its unspoiled charm and authentic cultural elements, sets it apart from many of the more tourist-focused areas along the coast. It's a lovely place for those seeking a more genuine Portuguese coastal experience, where the legacy of fishing traditions and the simple pleasures of a stunning beach remain central to the experience.

Praia da Tocha, a beach nestled along Portugal's Silver Coast, holds a unique charm stemming from its historical connection to fishing. Since 1945, the beach has been marked by the presence of original wooden fishing houses, locally known as "Palheiros." These structures, built on stilts, are a fascinating example of how fishermen adapted to the coastal environment, crafting functional yet aesthetically pleasing shelters. The choice of wood, a readily available material that provides both insulation and resilience against coastal winds and storms, highlights the ingenuity of the early fishermen. Analyzing the design offers insight into the evolution of coastal architecture in a relatively untouched setting.


While the region has transitioned from a purely fishing village to one that includes tourism, Praia da Tocha has retained its original identity and cultural heritage. This is somewhat remarkable, as it is less than 20 kilometers from the more tourist-heavy city of Aveiro, frequently described as the "Venice of Portugal". The relatively low impact of mass tourism allows visitors to experience a more authentic aspect of Portuguese coastal life.


The beach itself is a dynamic landscape, consistently reshaped by the tides and winds. This constant movement of sand creates ever-changing patterns and formations, making the beach's beauty a continuously evolving spectacle. The dynamic nature of the sands and the substantial waves that form here have also made Praia da Tocha a popular spot for surfers. This active environment attracts surf schools as well, allowing visitors with varying skill levels to engage with the power of the Atlantic in a somewhat controlled and safer setting.

Furthermore, the region offers opportunities beyond the typical beach experience. Bird watchers, for example, can experience a unique aspect of the region's ecology, as it lies on a major migration path for a variety of bird species, particularly during spring and autumn.


Praia da Tocha's culinary scene, somewhat surprisingly, remains rooted in tradition. Seafood, as one would expect, plays a prominent role, highlighting the connection between the people and the sea. This focus on fresh, local ingredients creates a unique dining experience, one less affected by the homogenizing influence often seen in highly touristic destinations.


Accessibility to Praia da Tocha has also improved with the rise of budget airlines serving the region. This, combined with the existing attractions, makes Praia da Tocha an increasingly desirable and cost-effective option for travelers seeking experiences away from more crowded tourist destinations.

The wooden fishing houses remain a centerpiece of Praia da Tocha's cultural heritage. Community efforts to maintain these structures are testament to the strong ties locals feel to the sea and their fishing traditions.


Finally, the landscape surrounding Praia da Tocha is a haven for those who appreciate exploring beyond the beach itself. Numerous trails are well-suited for leisurely walks, bike rides, or even horseback excursions, offering panoramic views of the coastline and highlighting the natural beauty that has shaped the area. The region showcases that while it's not actively marketed to tourists, it possesses a range of attributes that makes it a hidden gem.



7 Hidden Gems Along Portugal's Silver Coast A Two-Week Journey from Nazaré to Aveiro - The Ancient Salt Pans of Aveiro Now Producing Premium Fleur de Sel





The historic salt pans of Aveiro, with their roots stretching back to the 9th century, are experiencing a renaissance, now producing the coveted Fleur de Sel. This premium sea salt, prized for its fine texture and ability to enhance flavors, is harvested using age-old methods. The process depends on perfect weather—sun, wind, and specific temperatures—to create the delicate salt crystals that float on the surface of the seawater.

These salt pans, nestled within the stunning Ria de Aveiro, are a fascinating blend of tradition and natural beauty. They have become a draw not just for food enthusiasts, but for anyone who enjoys discovering how things are made. Guided tours offer a peek into the historical techniques used to harvest the salt and provide insight into the wider environment of the Ria, a winter haven for a massive number of migratory birds. Further adding to the area's unique appeal is a mud spa using the salt-rich mud that's found there.

While Aveiro is best known for its canals and its charming cityscape, these salt pans are a hidden treasure within the city. As travelers search for more authentic, local experiences, the resurgence of Fleur de Sel production adds a compelling layer to Aveiro's already attractive landscape.

The salt pans of Aveiro, located in Portugal's Ria de Aveiro, have a history stretching back to Roman times. They represent a fascinating intersection of human ingenuity and the natural environment. This region has been producing high-quality salt for centuries, a practice that was crucial before modern refrigeration became widely available. It's intriguing how these ancient techniques remain relevant today.

One of the key products emerging from the Aveiro salt pans is Fleur de Sel, a premium variety of sea salt. Fleur de Sel, literally "flower of salt," forms on the surface of seawater under specific conditions. It's collected manually, showcasing the labor-intensive nature of this unique salt. The texture and flavor profile of Fleur de Sel differ markedly from table salt, as it retains several trace minerals like magnesium and potassium. This gives it a subtle but distinct flavor appreciated by chefs and discerning eaters alike.

The production process relies on specific meteorological conditions, primarily the balance of sun, heat, and wind, which dictates the evaporation rate and ultimately, the quality of the salt produced. The weather in this area, coupled with the geography of the Ria de Aveiro, shapes the nature and quantity of the salt harvested each year. It’s a constant dance between nature and the expertise of the salt producers.

The salt pans' presence adds an interesting dimension to the ecosystem of the Ria de Aveiro. Being a lagoon system with diverse habitats, the pans support over 20,000 migratory birds during the winter months, highlighting the ecological role of these seemingly simplistic operations.

Beyond ecological importance, there's a cultural and tourism component to Aveiro's salt pans. It's become a point of interest for those seeking to experience the local culture and learn about traditional salt making. One salt flat, Noeirinha, even incorporates a mineral-rich mud spa. The notion of therapeutic mud and salt treatments is not new, and this speaks to a potentially wider range of applications for the salt itself beyond food.

The salt industry in Aveiro hasn't been without its challenges. Competition from industrialized salt production and a changing environment have put pressure on traditional methods over time. The adaptation of these ancient practices is an interesting study.

From a historical standpoint, the Aveiro salt pans have been instrumental in the local economy and have played a critical role in food preservation techniques. It’s curious that, today, the Aveiro salt pans are attracting international attention for their artisanal, Fleur de Sel. This illustrates how the ancient tradition of salt production continues to be relevant in the face of change. It’s a perfect example of a traditional activity merging with a modern desire for authentic and natural products.



7 Hidden Gems Along Portugal's Silver Coast A Two-Week Journey from Nazaré to Aveiro - São Pedro de Moel Lighthouse Trail and Secret Beach Access





7 Hidden Gems Along Portugal’s Silver Coast A Two-Week Journey from Nazaré to Aveiro

São Pedro de Moel, a charming coastal village nestled along Portugal's Silver Coast, offers a delightful mix of natural beauty and relaxed vibes. A hike along the São Pedro de Moel Lighthouse Trail reveals stunning coastal scenery and hints at the area's historical importance. This trail is a great option for anyone interested in combining outdoor exploration with a touch of cultural discovery.

The trail is also a gateway to some rather secluded sandy stretches, offering a hidden beach access experience. These coves are often peaceful and perfect for a relaxing day or for enjoying some of the area's calmer surf conditions. In fact, the calmer waves and larger sandy beaches make it a good choice for board surfing, especially if you are new to this water sport.


Surrounding São Pedro de Moel, the extensive Pinhal de Leiria pine forest provides a great opportunity for leisurely activities, such as cycling along the coastline or enjoying peaceful hikes in a remarkably old forest. This forest is one of the largest pine forests in Portugal and a key part of what gives the area its unique character.


São Pedro de Moel strikes a lovely balance between untouched nature and a slower, more relaxed coastal atmosphere. Travelers who prefer to avoid crowded tourist hotspots will find a great escape here, especially compared to some of the more well-known destinations like Nazaré. While still accessible, this spot feels secluded and authentic in a way that helps to define it as a real hidden gem along Portugal's Silver Coast.

São Pedro de Moel, a small coastal village north of Nazaré, presents a compelling blend of natural beauty and history, nestled within the vast Pinhal de Leiria pine forest. It's an area that's largely bypassed by mass tourism, offering a tranquil escape for those seeking a genuine Portuguese coastal experience.

The São Pedro de Moel Lighthouse, erected in 1903, is a prominent landmark, standing at 24 meters tall. Its Neoclassical design, a style favoured during the early 20th century, suggests a desire for both robustness and elegance—essential attributes for a structure guiding ships away from the hazardous coastline. Its beam can be seen for 22 nautical miles, a vital navigational aid in these waters.

The trail towards the lighthouse itself is fascinating, traversing a landscape shaped by limestone and sandstone formations, remnants of a far older geological timeline. These rocks reveal layers that are millions of years old, providing a glimpse into the region's fascinating history. It's a journey through time in a sense.

The path leading to the 'secret beach' also offers a compelling botanical component. Maritime pines, with their remarkable adaptability to the saline environment, dominate the vegetation. These trees play a critical role in soil stability, preventing erosion and preserving the integrity of the coastal trail. This is particularly fascinating from an engineering perspective, as it illustrates a natural way to solve issues that would otherwise require human intervention.

This 'secret beach' itself offers a fascinating look into the local biodiversity, serving as a habitat for a variety of marine species and avian life. It's a testament to the ecological richness found away from the more frequently visited parts of the coast. It's certainly an environment that deserves more attention, if only from the perspective of biological engineering.

The ocean's tides are a constant element in the area, creating diverse micro-habitats. They reveal and conceal areas of the coastline, creating unique conditions that foster a variety of marine life, especially during periods of low tide. The dynamic nature of this environment can be a real source of wonder for researchers.

Near the lighthouse trail, one can also discover evidence of the region's historic role as a stone quarry. These quarries, which were integral to Portugal's construction industry in previous centuries, are now remnants of a different economic era, highlighting the constant shift in human resource usage.

The summer months also present an interesting phenomenon: upwelling. In this process, cold, nutrient-rich waters rise from the ocean depths, nourishing the local marine ecosystems and supporting a strong local fishing economy. It's a natural process that highlights the delicate balance of the region's ecosystems.

The 'secret beach' is not easily accessed, requiring a descent down steep, and in some areas, unmarked paths. This factor, in a way, enhances its allure as a destination for those seeking a bit of seclusion and respite from crowded tourist beaches.

The area is becoming more accessible thanks to the growth of budget airlines operating in the region. This opens up the potential for tourists who may not be willing to spend a fortune to explore the area, fostering wider interest in this fascinating spot. In a sense, the growing ease of access presents a great opportunity to study the impact that human interaction can have on such a pristine environment.
