Casma Province: Archaeology and Notable Sites

Playa Tortugas, Las Aldas, and Cerro Sechín offer different points of reference for planning a trip to Casma Province: a precise geographical location, an archaeological complex with a distinctive sequence of plazas, and a façade featuring carved stone images. Playa Tortugas is in the Comandante Noel District, north of the city of Casma and at kilometer 395 of the Panamericana Norte. This location helps distinguish Playa Tortugas geographically from the city of Casma. The archaeological sites, in turn, raise questions about historical functions, architectural forms, and visual art.

Las Aldas: Architecture and Access

Las Aldas was an urban center with administrative and ceremonial functions. The main temple consists of a series of rectangular plazas; one of them contains a large circular plaza. This sequence invites you to view the complex not just as a single structure, but as an interplay of basic forms. The transition between rectangular spaces and the circular plaza gives the architecture a concrete focal point for exploration.

The final approach to Las Aldas leads from the parking area along an 800-meter walking trail and takes about 15 minutes. Factor this approximate walking time into your plans, and check trail conditions before your visit. This allows you to account for the described route as a distinct part of your visit.

Stone Art and Cultural Heritage

At Cerro Sechín, the façade takes center stage: it consists of carved stone slabs depicting warriors in a procession. Alongside Las Aldas's spatial layout, this offers a second way to explore the archaeology of Casma Province—through images and their arrangement on a structure. Cerro Sechín was declared Cultural Heritage of the Nation by Peru's Ministry of Culture under Vice-Ministerial Resolution No. 239-2010-VMPCIC-MC, dated December 13, 2010.

The wider travel destination of Ancash is also home to the Chankillo archaeoastronomical complex in Casma Province. It is Cultural Heritage of the Nation, has been inscribed on the UNESCO World Heritage List since 2021, and is recognized as the oldest solar observatory in the Americas. The solar observatory consists of thirteen towers aligned from north to south along a hill. They track the sun's annual course, including the solstices and equinoxes. This adds further questions to those raised by architectural forms and stone images: how can the sun's course be read from a built structure?

Ancash in a Broader Context

Looking beyond Casma to the wider travel destination of Ancash reveals other landscapes and activity options. Huascarán National Park covers 340,000 hectares; its landscape features include up to 27 snow-capped peaks higher than 6,000 meters. Laguna Chinancocha is in the park, in a glacial valley between Nevado Huascarán and Huandoy. Visitors can go boating there and hike the Chinancocha interpretive trail.

Laguna 69 is also among the natural attractions in the wider destination of Ancash. It was formed by the melting of Nevado Chacraraju. The trail starts at Cebolla Pampa; the hike can be completed in a day. The time estimates for Las Aldas and Laguna 69 refer to different routes and destinations: the final approach to Las Aldas takes about 15 minutes, while the hike to Laguna 69 can take a full day. This difference can help you weigh archaeological visits against a longer hike when planning your trip.

When choosing a vacation rental in Casma Province, start with your interests: would you like to focus on archaeological forms and artworks, or place Playa Tortugas as a geographical point of reference? If you also plan to explore the natural attractions of the wider destination of Ancash, include them in your itinerary as a separate regional focus.
