The Gredas de Bolnuevo make the landscape around Bolnuevo distinctive with their unusual shapes: they reach up to ten metres in height and are considered the most representative example of differential erosion in the Murcia region. In MazarrĂłn, they are protected both as a natural monument and designated as a site of geological interest. Those interested in landforms will find a clear focus for their stay here.
Gredas and Mountains: Nature Under Protection
The protected status also matters when visiting. The Gredas should neither be touched nor climbed, as this could seriously damage them. Viewing the formations while keeping your distance go hand in hand here. Bolnuevo’s natural setting can also be explored through the Sierra de las Moreras: Bolnuevo lies at the foot of this protected mountain area.
The Sendero Calas de Bolnuevo offers a different perspective. The trail is 7.1 kilometres long and runs through the protected area of the Sierra de las Moreras. Some of the protected islets in the Mediterranean can be seen from the route. This brings two different aspects together when planning nature activities: the geological formations of the Gredas and a designated hiking route with views of islets. The trail length is a concrete point of reference if you want to include a hike in your day’s plans.
For travel, there is a bus stop on the Mazarrón–Murcia line at Playa de Bolnuevo. If you plan to use this connection, check the timetable before your trip.
Coastal History and an Annual Event
The Torre de los Caballos offers a historical perspective on Bolnuevo. It was built in the 16th century to monitor the coast against possible incursions by Barbary pirates. As part of its musealisation, the exhibition content was updated and assembled, and new interpretive signs were installed. Check current visiting arrangements before you go, as details of the facility may change.
The pilgrimage also gives your trip a specific date to plan around. It takes place every year on the Sunday after 17 November, from the sanctuary in MazarrĂłn to the hermitage on the beach in Bolnuevo. Participants gather on the beach and grill sardines over improvised fires. If you want to include this event in your travel plans, check the programme for the relevant year in advance. This helps distinguish the recurring event from a visit planned independently of a particular date.
When choosing a holiday rental in Bolnuevo, your interests can guide your decision: geology and protected landscapes, a hike, or coastal history each offer a different focus. The pilgrimage is an additional event held on a set date each year. This selection can help you tailor your stay to the reason for your trip without assuming that every activity calls for the same day plan.
