The Ermita de Santa Ana is located in the port area of Castro Urdiales. It's easily accessible on foot from the town center, particularly the Puebla Vieja area. Parking might be challenging in the immediate vicinity, so walking is often recommended.

Parking directly at the hermitage can be limited. It's advisable to look for parking in the main town or port areas and then walk to the site.

Access to the exterior and the viewpoints is generally free. The interior, which houses a small museum, may have specific opening hours and potentially a small admission fee, though some reviews suggest it's free. It's best to check locally for current access policies.

The exterior and views are accessible at all times. The interior museum's opening hours can vary, and it's recommended to check locally or with the Castro Urdiales tourism office for the most up-to-date information.

Access involves climbing a few steps to reach the hermitage and its viewpoints. While the steps are described as well-maintained, individuals with significant mobility challenges might find it difficult.

For photography, early mornings or late afternoons (golden hour) offer the best light for capturing the coastal scenery and the hermitage. These times also tend to be less crowded.

The viewpoints offering panoramic views of the port, the Lighthouse Castle, and the Cantabrian Sea are the most photogenic. The exterior architecture itself also makes for interesting shots.

Originally built as a watchtower, the hermitage has maritime traditions and may have Roman origins. It served as a meeting place for navigators and sailors. The current building is a reconstruction from 1941, incorporating older archaeological remains.

Inside, you can find well-explained archaeological remains with signage, including remnants from the Solutrean, Roman, and medieval periods. There's also a short video detailing its history.
