Description of the walk

By car, park in the car park at the bottom of the village, on the west side, on the road to Vera.

(S/E) Start on the other side of the road; signs indicating the start of the various routes will help you. Choose the direction: From pass to pass.

Walk along the road for 10 minutes, then turn left onto a dirt track marked with yellow signs, which climbs quite steeply. After 700 metres, the track reaches a small plateau with wooden sheepfolds opposite and a magnificent stone house on the right, which we will see better further up. From there, climb up to the left along this path, which after 10 minutes passes in front of a water collector.

(1) Continue north-west on the main path, ignoring the paths branching off to the right and left. You will arrive at a grassy plateau from where you can see, to the north, the Nivelle river flowing into the bay of Saint-Jean-de-Luz.

(2) Continue along the path that climbs upwards, keeping the Rhune antennas in your sights. Ten minutes later, before reaching the railway line, turn left, then right, heading southwest, and join the GR®10.
>Walking along the railway line is strictly prohibited, at least during the period when trains are running.

(3) Follow it to the right, north-west, and arrive at the pass with several directions very close to the railway line.

(4) Just before the railway line climbs towards the summit, turn left onto the path (south), initially following the power line. You will reach the Col d'Athkalum (where you will see a mixture of puddingstone and flat, sloping rocks).

(5) Descend the path heading south and arrive at a large crossroads.

(6) Continue straight ahead, passing a stone sheepfold and crossing a stream.

(7) At the fork, turn right and then left 100 metres further on. A few minutes later, you will reach a gap, which is an ideal spot for a break.

(8) Continue downhill to reach Sare. At the foot of the mountain, you will find the old Olhain Chapel.

(9) Turn left (north). At the fork, leave the wide path and take a narrower path on the right. You will come to a wide track which you should follow to the right until you reach the road.

(10) Follow the road to the right for about 350 metres, then leave it on the left and take a stony path. Back on the tarmac, turn right and continue to the D406.

(11) Follow this road straight ahead to the car park (S/E).

A very pleasant route, quite challenging, with magnificent panoramic views throughout the climb to the Atakaleum pass. I recommend this climb to then continue on to the summit of La Rhune, which adds 60 to 90 minutes to the route but is well worth it in my opinion. I will be trying this alternative route soon.
The return trip is more leisurely and just as pleasant, with a few shaded sections, and largely follows the trails of the "La Rhune via the reservoir" hike.
I recommend this route (+ the climb to La Rhune), which is off the beaten track (not very busy) and offers the most beautiful views: the entire coastline and the surrounding peaks.

Advise following the tracks for 1 kilometre when there is a sign prohibiting walking along the railway line...? We had to take a detour, which significantly lengthened the journey

Walking along the railway line is strictly prohibited, at least during train operating hours. This route is marked and signposted (yellow PR), and the official route bypasses Mount Altsanga, then crosses the railway line again. After that, you have to descend a little to reach the edge of the pine forest. This route is magnificent, and as a bonus, you can see the little Rhune train passing by.

Very nice route, quite busy despite wet weather and strong winds!
I would advise against following the railway line, as it doesn't seem very safe and I even wonder if it isn't strongly discouraged or even prohibited. Of course, the trains aren't running at this time of year, but there may be maintenance work going on, and people tend to follow bad habits. So, rather than following the railway line, we went around Altsanga.

A beautiful route with superb views. It was very windy that day, but the sky was blue. We came across lots of Pottoks and spotted a few birds of prey.
The only downside was the final stretch (about 1 km) along a road.

A very pleasant route with beautiful panoramic views. I was lucky enough to see vultures up close. We always encounter magnificent pottocks on these mountains.

First of all, thank you for this itinerary, Jacques Bomassi!

I did this hike on 7 March 2024. It was a fairly sunny day but very windy.
I met four people during the half-day. The pottoks were there as expected!
Points 6-9 are not very clear, but by reading the landscape, you can quickly find the route. At point 6, do not turn right, but take the left path.

Enjoy your hike!

A very beautiful route with the Rhune peak just above.
Physically demanding from the start, as is often the case in the Basque Country.
Suitable for all good walkers, best done in good weather.
If you're feeling brave and motivated, you can climb up to the Rhune for a drink or to refuel, adding an extra challenge.

A very beautiful hike with magnificent views all the way to the Pic du Midi d'Ossau, and with an added bonus at La Rhune from the Athkalum breach.

I really like this hike, which I've done several times. It's varied and beautiful, even when it's cloudy. Average length, no real difficulties.
