The route through Elorrio’s Historic Quarter begins in a parking area located between the town centre and the start of the historic ensemble, providing convenient access to the itinerary. From this point, visitors enter an area where the first stone houses and historic buildings begin to appear, integrated into a calm urban setting.

A few metres ahead is a small triangular square known as Plaza del Crucero de Santa Ana, where this heritage element is located. From here, the route leads into the main square of the historic quarter, one of the largest and most representative spaces on the itinerary. This square is home to the Basilica of the Immaculate Conception of Santa María. Access to the square includes a central staircase, but there is also a lateral ramp with a very gentle slope that allows the level change to be negotiated comfortably by people with reduced mobility, pushchairs, or mobility aids.

Under the basilica’s porticoes, the stone paving is somewhat irregular, as is typical in historic environments; however, it is not particularly difficult to navigate and can easily be avoided by using the more homogeneous perimeter routes around the square. During opening hours, it is possible to enter the interior of the church, a spacious area of great heritage value.

From the main square, the route continues along the principal street of the historic quarter, which is pedestrian in character and has carriageway and pavements at the same level, without kerbs or steps. Along this stretch, high-contrast wayfinding tiles (white and red) are integrated into the paving, indicating the location of historic façades, palaces, notable buildings, churches, and facilities such as the tourist office. These points include QR codes, which can be downloaded in advance from the tourist office—located opposite the basilica—and provide interpretive information during the walk.

The main itinerary continues a short distance further along this pedestrian street and then makes a brief return to the church square. From there, the route proceeds along a parallel street, allowing visitors to complete the visit by discovering additional palaces, stately homes, and historic buildings, closing the circuit comfortably and without significant slopes.

The complete route is approximately 700 metres long, mostly flat, and set within a compact urban environment. Along the way there are numerous food and drink establishments, particularly around the main square and adjacent streets, making it easy to take breaks and complement the visit with leisure and dining options.
