Route Overview
The PR1 PDL Sete Cidades Circular Trail begins and ends at the Vista do Rei viewpoint, which is easily accessible by car and near public transportation links. From this elevated starting point, the clearly marked loop trail heads northward along the rim of the volcanic caldera, following an undulating path that offers frequent access to high viewpoints over Lagoa Azul, Lagoa Verde, and the surrounding landscape. The route then gently descends toward the caldera floor, taking hikers through open meadows, forested stretches, and the picturesque Sete Cidades village at roughly the halfway mark, where services such as restrooms and refreshment stops are available.
After passing through the village, the trail follows rural tracks and secondary roads that hug the lake shore before gradually climbing back up the western rim, returning to Vista do Rei. Along the way, hikers will encounter other points of interest, such as the Aqueduto do Carvão, wooded sections filled with endemic Azorean flora, and multiple signed viewpoints including Miradouro da Boca do Inferno and outlooks toward Lagoa de Santiago.
The trail covers approximately 12 km and is typically completed in 4 to 5 hours at a moderate pace, with an elevation gain of around 450 meters. Trail surfaces include dirt, gravel, and rocky paths, which can be uneven or slippery when wet. Waymarking along the main route is consistent, but the use of GPS or an offline map is recommended to avoid confusion at certain junctions, particularly near the village and wooded sections. This hike is generally rated as moderate in difficulty and suits hikers with a reasonable fitness level seeking a full, scenic day out in the Azores.
Historical Context of Sete Cidades and the PR1 PDL Trail
The Sete Cidades region is steeped in legend and history, with the twin lakes—Lagoa Azul (Blue Lake) and Lagoa Verde (Green Lake)—at the heart of one of the Azores’ most enduring tales. According to local folklore, the lakes were formed from the tears of a princess and her shepherd lover, who were forbidden by the king to be together. Their sorrow birthed the two differently colored lakes, symbolizing their eternal bond and the richness of Azorean storytelling.
Beyond legend, the caldera itself is a remarkable geological formation, created by a series of volcanic eruptions that shaped São Miguel Island over millennia. Archaeological findings and early records indicate that the area was settled soon after the Portuguese discovered the Azores in the 15th century. Sete Cidades village, nestled within the caldera, became known for its pastoral charm and strategic position as an agricultural hub. Today, remnants of stone aqueducts and rural architecture along the trail serve as a testament to the region’s agricultural heritage and resilience against natural challenges.
As you hike the PR1 PDL trail, you’re retracing routes that were once vital for connecting isolated farming communities, transporting local produce, and forging the cultural identity of São Miguel. The landscape’s historical and mythological layers add depth to the breathtaking beauty, making each step a journey into both the natural and cultural legacy of the Azores.

Challenges to expect
The PR1 PDL (Sete Cidades Circular Trail) features some moderate elevation changes, with certain sections of the caldera rim involving sustained ascents or descents that can be physically demanding. These portions may be challenging for those unaccustomed to longer hikes or uneven terrain. The trail surface varies from dirt to rocky and gravel paths, which can become slippery, particularly after rain, so sturdy hiking footwear is strongly recommended.
Weather conditions in the Azores are famously unpredictable, even during the optimal hiking seasons in spring, summer, and autumn. Sudden rain showers and mist are common, sometimes reducing visibility along exposed ridgelines. It’s important to come prepared with rain gear and extra layers, and always check the local forecast before starting your hike.
Sections through forested or densely vegetated areas can sometimes be muddy or overgrown, requiring careful navigation. While the trail is generally well-signed, occasional intersections or side paths may require attention to avoid veering off course. A GPS device or offline trail map can provide added reassurance, especially for first-time visitors.
