If you are looking for a short but rewarding walk on the Costa Blanca, the Cova Bolumini in Beniarbeig offers history, views and a fascinating natural phenomenon all in one route.
Located in the Serra de Segària, this cave has attracted walkers, history lovers and photographers for years. The site dates back 13,000 years and is believed to have been used by early settlers, making it one of the most interesting hiking destinations in the Marina Alta.
But what makes Cova Bolumini extra special is the summer solstice phenomenon, when sunlight enters the cave and illuminates the interior in a fabulous display.
A short walk: Rewarding finish
The walk to Cova Bolumini is relatively short, but the climb can be steep in places. Most walkers with a reasonable level of fitness can complete the route without difficulty.
The route from Beniarbeig covers just under 3 km one way, with an ascent of around 270 metres. The climb usually takes around 45 to 50 minutes, depending on pace. The final section is the most challenging, with uneven terrain and a steeper incline near the cave entrance.
The trail follows the PR-CV 415 route, which is well marked along most of the way.
13,000 years of history
Archaeologists believe the Cova Bolumini has been used since the Epipalaeolithic period, around 13,000 years ago. Its importance grew during the Bronze Age, when the cave was used as a burial site.
Inside the cave, researchers have discovered rock art, including painted lines on natural formations. These findings suggest the cave may have served as a spiritual or ceremonial space for early inhabitants.
The name Bolumini may also connect to the geology of the area. Some historians believe it comes from “bol armeni”, a type of clay found in the Serra de Segària.
The summer solstice
One of the biggest attractions of Cova Bolumini happens around 21 June, during the solsticio de verano (summer solstice).
At sunrise in the days surrounding the solstice, sunlight enters the cave and lights up the interior. This natural phenomenon creates an amazing visual effect and connects the site with seasonal changes.
Researchers rediscovered this event in the late 1990s, and further studies confirmed its accuracy. Although there is no definitive proof that prehistoric settlers designed the cave around the solstice, the alignment makes it a unique location.
Cova Bolumini, Beniarbeig: Route
Most walkers start the route from Partida Tossals in Beniarbeig, where parking is available. The trail begins with a small incline along the southern side of the Serra de Segària, offering views across the valley.
As you climb, you will reach a key junction. Follow signs towards the cave and continue upwards. A large garrofer (carob tree) provides a popular rest point before the final climb.
Near the end of the route, you will also find the Avenc de Bolumini, a geological feature worth a short detour. From there, the final stretch leads to the cave entrance at just under 300 metres altitude.
Walking tips
The southern face of Segària can become very hot, particularly in summer. It is best to avoid walking during the hottest part of the day.
Wear suitable footwear with good grip, as the final section is uneven.
The cave contains protected wildlife and archaeological remains, so avoid touching the walls.
