Start:When you reach Montaña Blanca, follow the signs to the church. The car park is right next door.
(S/E) With your back to the church, turn right up Calle La Degollada. After the tarmac, continue straight ahead on the path (GR®131).
(1) Spot the return path on the left and go straight ahead. Pass the small pass and continue to a crossroad.
(2) Leave the GR®131 by taking a trace to the left, visible in the lava. Continue straight ahead along the side of the volcano, still following the track.
(3) Turn right towards the road on the most visible track.
(4) At the track junction, turn left onto the path parallel to the Tias-San Bartolomé LZ-35 road.
(5) At the intersection, take the track on the left (Calle Las Rosas), towards the cattle pen. Drive past it.
(6) At the intersection, turn left, then immediately right to follow the track.
(7) At the crossroads at a building, continue straight ahead, crossing the crater on your left to climb to the top of the volcano, following the tracks in the lava.
(8) At the top, climb down past a cross and rejoin the building.
(7) Continue along the path opposite, passing the cross and continuing on to a track.
(9) Turn right.
(10) Just before the first house, turn left as soon as possible to rejoin the original path.
(1) Keep right as far as the church and return to the car park (S/E).
