Estepona — Sierra Bermeja Loop
About this Route
A brutal and beautiful loop from Estepona harbour that climbs Sierra Bermeja's red peridotite flanks to 969 metres — with views of Gibraltar and the African coast — before winding through the white villages of inland Andalusia and descending back to the Mediterranean. One of the most concentrated climbing experiences in southern Spain, compressed into 89 kilometres.
The opening sets the tone: the road climbs straight out of Estepona harbour and barely lets up for the first 22 kilometres. The MA-8301 is legendary for having virtually no straight sections — an endless succession of hairpins through dense Pinsapo forest, a protected Spanish fir that grows almost nowhere else in the world. By the time the summit area at Los Reales opens up at 969 metres, over a thousand metres of climbing are in the legs and the coast is far below. On clear days the view stretches from Gibraltar to the Moroccan Atlas — two continents visible from the same saddle.
What comes next is what makes the route. After the descent into the Andalusian interior, the landscape shifts entirely — from red peridotite rock to the olive groves and whitewashed hilltop villages of the Pueblos Blancos. Gaucin is the natural lunch stop, a quiet square with a couple of good restaurants well suited to cyclists on a long day. From here the return leg is anything but flat: another 500+ metres of climbing through a series of ridges, with Peñas Blancas as the sting in the tail before the final descent back to the Mediterranean.
Sierra Bermeja traps heat in summer — spring and autumn are the ideal seasons, and the winds (Levante from the east, Poniente from the west) can be real on the exposed upper sections. Come when the temperatures are moderate, pace yourself on the lower slopes, and this is one of the finest mountain days in southern Spain.
I rode this in July 2025. Sierra Bermeja in summer is not the textbook choice — the heat builds fast on the lower slopes and the upper sections are exposed — but we started early and it was more than worth the effort.
Beautiful surroundings and an endless number of hairpins. That is how I would describe this route in one line. It is quite a hard day out — I will not pretend otherwise — but so worth it. The climb out of Estepona is relentless. The hairpins just keep coming, one after another, winding up through the pine forest with the sea dropping away behind you. There are hardly any flat metres to recover on. At the top, though, the views make the effort make sense — the Mediterranean on one side, Africa visible on a clear day, Gibraltar down the coast.
Gaucin is the right place to stop for food on the return. There are a couple of restaurants to choose from on the square and it breaks the ride up at the right point. One warning: do not start too hard. There is a lot of climbing after Peñas Blancas that catches people out if they have spent everything on the first summit.
Kilometre by Kilometre
The route leaves Estepona harbour and wastes no time. The climbing begins within the first kilometre and builds relentlessly up the MA-8301 — a road with virtually no straight sections — through dense Pinsapo forest to the Los Reales summit area at 969m. Over 1000 metres of elevation in 22 kilometres. The views back over the Costa del Sol and across to Africa open up progressively as you climb.
After the summit the route descends into the Andalusian interior. The landscape changes completely — from the red peridotite rock of Sierra Bermeja to a quieter, more sheltered valley with olive groves and the classic white villages (Pueblos Blancos) clinging to the hillsides. Gaucin is the natural stop for food and water at around the halfway point.
The return leg is far from flat. The route climbs back through a series of ridges and valleys with another 500+ metres of ascent across this section. The roads are quiet, the scenery is Andalusian at its finest, and the legs are starting to feel the morning's efforts. Peñas Blancas is the key climb to navigate in this section — take it steady.
The route finds its way back down to the coast through a series of sweeping descents. The Mediterranean comes back into view and the air warms noticeably as you lose altitude. The final kilometres bring you back through Estepona and to the harbour where the ride began.

Key Climbs
Tips & Local Knowledge
- Start from Estepona harbour and grab a café con leche before you begin — the climbing starts almost immediately.
- Don't go out too hard. The first major effort comes early, but there is significant climbing again after Peñas Blancas — pace yourself accordingly.
- Gaucin is the natural lunch stop in the white villages section — a couple of good restaurants on the square.
- The Pinsapo forest near the top of Sierra Bermeja is a protected and rare species of Spanish fir found almost nowhere else in the world — worth stopping to take in.
- On clear days you can see Gibraltar, the Moroccan Atlas mountains and two continents from the upper sections of the climb.
- Avoid the hottest summer months — Sierra Bermeja traps heat and midday temperatures on the climb can be extreme. Spring and autumn are ideal.
- Be aware of strong winds (Levante from the east, Poniente from the west) on the exposed upper sections of the route.
