Description of the walk

Refuge Aterbea car park (1,138 m) on the right after the D301.

(S/E) From the car park, follow the GR®10. Head south on the D18 for about 800 m. Pass the Pedro chalet on your left.

(1) At the fork, head west on the GR®10.
Turn west onto the GR®10 and head for the Occabé plateau, at around 1,430 m.

(2) Leave the GR®10 by turning left, heading south, and reach the summit of Occabé.

(3) Descend northwards, join the GRT09 and turn right to visit the Occabé plateau and the Occabé Cromlechs Megalithic Site.

(4) Return via the GR®10 trail, heading south for about 200 m, approaching the crest of the plateau. Reach a fork in the trail at an altitude of about 1,385 m and leave the GR®10 trail.

(5) At a hollow, head down eastwards along the path that joins the forest below.
Follow this wide path through the forest until you reach the D301.

(6) Continue right on the D301 for about 500 m until you reach a right-hand bend. Look for a path on the left.

(7) Leave the D301 on the left and follow the path that heads east, then south-east into the valley.
Continue along this path, which passes partly through the forest, and join the D18, then follow it to the right to return to the car park (S/E).

We really enjoyed this circular walk starting from Chalet Pedro, as mentioned in the title, but please note that on the route map, the start and finish are always at the Aterbea refuge.
We loved this whole plateau section where the mountains are covered in a blanket of grass. We had our dog on a lead (which, apparently, not everyone still understands...).
We settled down at the summit of Occabé, alone in the world, for a picnic with a view of the snow-capped peaks! The sections through the woods are very pleasant. It’s towards the end, when you have to follow the road, that the paths aren’t always suitable. We had a brilliant time.

I would just suggest a slight change to the parking arrangements to shorten the route a little. Park opposite Chalet Pedro, where there is a large car park, and take the GR 10 trail, which starts just next to it and climbs steeply.
From the plateau, return via the forest path downhill, which joins the D 301 to complete the circular route back to Chalet Pedro.

A magnificent hike combining forest, mountain pastures and small streams... a splendid 360° view from the summit, surrounded by sheep and horses roaming free. Be sure to bring protection from the wind at the summit... easy-to-follow directions. There is a slight uncertainty at point 5 when descending into the "basin", but this is indeed the correct direction, as the path becomes immediately apparent once you reach the forest.

A very beautiful hike with stunning panoramic views.
Best done in good weather when it's not too hot.
The cromlechs are mysterious...

A beautiful and varied hike. Forest trails alternate with magnificent 360° panoramic views. There are a few good climbs and descents, but nothing impossible. No particular difficulties and beautiful scenery. Thank you for this route.

A good climb through the superb Iraty beech forest, with a few steep sections, took us to the flanks and then to the summit of the Okabe. On the eve of Ascension Day, a sunny day with mild temperatures, we were treated to a 360° panorama as green as ever. The snow-covered Pyrenees were clearly visible that day. The reward after the 4km effort was magnificent. The descent required good footwear: pebbles, damp areas and even mud in places. We always follow the GPS route (downloaded) and this loop proved to be very pleasant and interesting. Thank you for this lovely route, which was very little used that day.

A very pleasant hike in a rather cool May with quite a bit of rain beforehand.

As a result, all the landscapes were a vibrant green on a sunny day. We thoroughly enjoyed ourselves. The beech forest was magnificent.

We did the walk with a 10-year-old child (who is used to going on walks from time to time) and took it fairly easy. It only took us 25 minutes longer than the indicated time.
Thank you for this lovely walk.

A very beautiful hike, with varied and pleasant landscapes and paths. Well marked. However, it was very crowded (almost too crowded...) for a Halloween weekend. The entire descent is along the river, which is really nice! The hike is more than manageable despite a steep climb at the beginning. I highly recommend it!

This walk is best enjoyed on a day with clear skies. Cloudy conditions can make the scenery very disappointing.
A steep climb from the outset, followed by the splendour of the Basque countryside.
Return and stop to buy cheese.
Downloading the route is essential, as there is very little mobile phone coverage.

A lovely loop; even the slightly monotonous track at the start is forgotten thanks to the beautiful beech forest.

Hike completed with a group of more than 20 people, including adults and children. The moderate difficulty level meant that even children and adults who are not particularly athletic were able to keep up without too much difficulty . The hike is varied and the scenery is superb. The weather was sunny and quite warm, but there are several shaded sections and a few nice spots for a picnic. Surprisingly, there weren't many people, even though it was the middle of the week of 15 August. The icing on the cake was the last section along the river, which was very nice and ended at a cheese shop and bar with tables by the river (unfortunately closed that day).

Very nice, the return off the marked trail allows you to be alone in the forest and adds something extra.
