Buses stop at just over 900m (2950ft) at Degollada de Peraza, where there is a map-board and nearby bar restaurant. Follow Ruta 29 downhill for La Laja, soon keeping left at a junction to leave the GR131. The steep, winding, stone-paved path offers splendid views across the valley. Agaves, cistus and asphodel grow beside the path, with pines and tabaibal further down, and palms later.
Pass a ruined caseta and prickly pears. After turning round a side valley there is a good view of La Laja, with pines rising to the domes of Los Roques. Stone-paved zigzags drop into a valley. Climb up the other side, cross a slight gap and pass an almond tree. The path zigzags down past palms and reaches the first few houses in La Laja. Turn left as signposted for Los Roques. If starting from La Laja, find an electricity transformer tower on a road bend. Go down steps and turn right. Cross a concrete bridge over a stream. Zigzag up past houses and turn right as signposted for Los Roques.
Looking towards the domes of Los Roques from a high part of the walk
The path rises, with some level stretches and a water pipe alongside. Reach another junction and turn left up a stone-paved path beside pines. The path turns a corner and crosses a dip. Steps and tight zigzags climb through a forested side-valley, where stout eucalyptus trees have been felled or burnt. Leave the valley and start a climbing traverse across a slope of pines, crossing a couple more side-valleys on footbridges. There is a slight drop into another side-valley to cross another footbridge then the path climbs through the forested valley. A gap and a crumbling caseta are reached, with the mighty domes of Los Roques beyond.
Stone steps are climbed to join a main road near Roque de Agando
Turn left up a path and pass a ‘limite del parque’ notice. Heather trees appear as the path climbs the forested crest. The Roque de Agando comes into view and the broad path ends with flights of stone steps climbing to a main road. For a closer view of Roque de Agando turn right; otherwise turn left to return to Degollada de Peraza. The GR131 runs beside the GR131 beside the main road. See the middle of Walk 27 to follow the GR131 back to the start.

Risco de la Fortaleza is completely surrounded by cliffs on a rocky ridge high above San Sebastián and Playa de Santiago. A rugged path approaches it, and an interesting circuit takes in ruined farmsteads on exhausted, arid terraces at Morales and Casas de Contreras.
Little casetas are passed soon after the start of the walk alongside Risco de la Fortaleza
Buses stop at just over 900m (2950ft) at Degollada de Peraza, where there is a viewpoint, map-board and a nearby bar restaurant. Between the viewpoint and the bar, steps drop down from the road, passing a little house. Follow a path down into a barranco, passing palms and agaves, to around 750m (2460ft). Climb gradually to reach a junction on a ridge, beside ruined casetas at Berruga. Turn left to continue along the combined Rutas 25 and 28.
Go down rugged and easy stretches of path, passing palms, agaves, prickly pears, cistus, tabaibal and tagasaste. The path is mostly downhill, but there are a couple of short, steep, stone-paved ascents on the slopes of Alto de Tacalcusie. Eventually, the path turns gradually left and levels out among palms and agaves. Rise past terraces to reach a gentle gap at Llano de la Cruz, at 722m (2368ft).
There is a path junction, and the plan is to turn left along Ruta 28, return to this point later on Ruta 25 and then retrace the route back to Degollada de Peraza. First, turn left as signposted for Morales. The path climbs gently before descending, Note a solitary ruin, but keep an eye on yellow flashes as the path crosses old terraces covered in tabaibal. Drift towards the edge of the Barranco del Cabrito, then away from it, then back towards it.
Walk down towards a ruin, but watch for a sudden right turn away from the barranco. The path leads down to another ruin, then afterwards turns left at a junction to pass yet another ruin. Level out and reach a signpost at the ruined village of Morales, around 520m (1705ft). The buildings are worth exploring, but take care as some are close to collapse.
The Bar Restaurante Degollada de Peraza and Alto de Tacalcusie
Turn right, as signposted for the GR132 for Casas de Contreras, down a rocky path to cross a barranco, then up across a slight gap. Go down to cross another barranco then up across a terraced slope. The path drifts down to a rock wall, which is climbed using a breach; then a gentle descent crosses a terraced slope. A rugged path drops into a barranco and climbs up the other side past a ruin. Watch carefully at a corner, turning right to drop into a deeper barranco. Climb the other side to a ruined mansion at Casas de Contreras, at 400m (1310ft).
Turn right at the crumbling ruins of Casas de Contreras as signposted uphill for the Ruta 25 back to Degollada de Peraza. Climb past the house and the prickly pears behind it. Go up a rocky, boulder-paved path that rises along a low, rocky ridge between terraces covered in tabaibal. Keep climbing to pass three ruins and the path finally levels out at Llano de la Cruz, returning to the path junction reached earlier in the walk. Turn left downhill, as signposted and simply retrace the earlier steps of the day to return to Degollada de Peraza.
