From the village of La Thuile, take the road to the ski lifts and head up the valley to La Joux.
Park at the first car park, just before the restaurant.
(S/E) From the car park, join the path on the left signposted Alta Via No. 2 (a ‘2’ on a Yellow Triangle), No. 3 (Refugio Deffeyes) and No. 8 Laghi di Bellacomba. Follow this pleasant path until you reach the first waterfall.
(1) Turn left and, still following the Alta Via No. 2, continue to a junction signposting thethird waterfall (Terza Cascata del Ruitor).
(2) Leave the path to the waterfall on your right and continue to the left until you reach another fork where paths No. 3 and No. 8 split.
(3) Carry on straight ahead towards the refuge (signposted AV2 and No. 3). After a few bends, you’ll gradually emerge from the woodland onto a small plateau (Pian de la Liere) and reach the small Glacier Lake, a perfect spot for a break.
(4) From this point, the rest of the route is easy to follow. Resume the ascent towards the refuge and, via numerous bends through the rocky terrain, reach the Alpeggio del Ruitor, a small pass offering panoramic views of the Mont Blanc massif to the north-west and the Ruitor Glacier to the south-east. Continue along the path to the Rifugio Deffeyes, which is now very close by.
(5) Walk round the refuge and, heading south-west, take the path leading to the Santa Margherita Al Rutor Chapel.
(6) Return to the path towards the western end of Lago Inferior del Ruitor and continue to the left.
(7) Still heading south-west, walk towards another lake, Lago dei Seracchi. Walk past it and come to a fork in the path.
(8) Leave the path for the standard route up the Grand Assaly on your left, and continue westwards on the path signposted ‘Laghi di Bellacomba’. Enter the Vallone Di Bella Comba, reach a small bridge over a stream and cross it.
(9) Turn left onto path No. 8 towards the first Lake Bellacomba.
(10) The second lake is easily reached.
(11) Return along the same route.
(9) Stay on the left bank of the stream, following path No. 8 straight on, and descend to a junction.
(12) Turn right towards the east and, still on path No. 8, continue to another junction.
(13) Ignore the path on the left, cross the Ruitor stream and rejoin Path No. 3, which you used for the ascent to the refuge.
(3) Take your time returning along the same route you took on the way up to the car park (S/E).
