Description of the walk

Park in the Muandes de Bourlinche car park.

(S/E) Take the Pépinières trail opposite the car park, indicated by a sign. Begin a steep climb on this winding trail through the woods. Join a track and continue on the Pépinières trail. You will soon reach a crossroads.

(1) Take the right-hand path, make a large bend before rejoining the Sentier Widman. Take it to the left and continue along this path to reach the Chapelle des Séyères.

(2) Continue straight ahead, quickly reaching a fork, then turn right, still on the Sentier Widman. You will reach a hairpin bend marked by a cairn.

(3) Turn left and continue along three large hairpin bends to reach the summit of Mont Guillaume and its chapel.

(4) Take the path opposite and follow the ridge.

(5) Reach Mont Guillaume, then the summit of this ridge.

(6) Then begin the descent and quickly reach the Col de Trempa-Latz.

(7) Turn right onto the path that descends into the valley, then follow the Torrent de Sainte-Marthe to Séyères.

(2) At Séyères, follow the route taken on the way up to return to the initial crossroads passed on the way there.

(1) Leave the route you have already taken and take the path on the right, cross the Torrent de Sainte-Marthe ford, and continue along this path, keeping to the left at the next crossroads. You will come to a forest track.

(8) Turn left onto this track to return to the Muandes de Bourlinche car park (S/E).

Clear map for a superb route with magnificent scenery. The trail on the eastern slope of the Tempra-Latz pass is excellent despite the fairly steep gradient. Starting from the Muandes de Bourlinche car park is an interesting option, with fewer cars than at the forest car park.

Very beautiful route, magnificent hike. No difficulty (if you are reasonably fit).
On 4 August, there were quite a few people, but nothing too bad. Thank you!

A very beautiful hike. Be sure to follow the route. Both chapels are open to the public and have water available. Be aware that it can be quite windy at the summit, so bring warm clothing if you plan to stop for a picnic. The 6-hour estimate includes breaks and lunch, but experienced hikers can complete it in 4 hours. The view from the summit is exceptional. A must-do!!

A very beautiful hike. Moderately difficult due to the elevation gain of over 1,000 metres.
Very rich biodiversity at this time of year in terms of alpine flowers.
Best enjoyed in the off-season due to high visitor numbers in July/August.

despite the 1,000m elevation gain, the trail climbs gradually in switchbacks and what a reward when you arrive at the chapel with views of Lake Serre Ponçon, of course, but also the Viso, Brec de Chambeyron, Roche Brune, Bric Bouchet... A breathtaking 360° view, very windy on the ridge

Superb hike. Easy to follow path as Mont Guillaume is clearly signposted throughout.
The car park isn't easy to find if you're not familiar with the area... Maps isn't very good at showing forest trails! From Embrun, just follow the signs for Mont Guillaume, continue along a small road and then a forest track. Suffice to say, it's not recommended for vehicles that are too "sensitive".
A slight variation is to park at the Para viewpoint, 3 km further by car, then return via a well-marked trail. It doesn't add much to the length of the hike and is really worth a look!

This comment is a bit late, but since I plan to climb Mont Guillaume again, I'll summarise. On 19 June 2021, sand blown in from the Sahara greatly obstructed the view, so I'll have to do it again because this hike is very interesting.
On that day, there was still too much snow to complete the circular route via the pass, so we shortened the circular route.
One downside for the return between points 1 and 8: although a comment indicates recent logging, before the logging, finding the right path was a real adventure... not to mention the passage that was not so easy to spot and very slippery. I therefore agree with gfeller's comment that it is better to stay on the path you took on the way up

A beautiful circular route, better than the classic return trip to the chapel. However, the alternative descent between 1 and 8 is no longer of interest, as the track has been ruined by recent logging. It is preferable to stay on the ascent path
