From Thumel Village to Basei Pass
1)- Basic Itinerary n° 1: from Villeneuve Municipality to alternative Valsavarenche/Rhêmes Valleys with Regional Road; from fork towards Introd, Brenloz/Tache Hamlets, Rhêmes-Saint Georges Commune, Proussaz (1445m; Holiday Farms"Le Baton 'Or" and "Le Vieux Creton" nearby Creton (1447m, 1548m) and"Edelweiss" (1600m), below Melignon, Artalle (1654m), Carré (1664m) Villages to Main tourist center Rhêmes-Notre Dame (1723m). Continue on asphalt road towards Bruil (1723m), Moulin de Chaudanne/Pellaud (+; 1811m) Villages to Thumel Villages neighbor the torrent into a grassy plaine (1879m; great dirt parking immediately before the same in altitude 1848m; signal no passage). From this, before with dirt farms road to winding road 1901 metres (various signals, panels), after through path in South and towards Saint Pantaléon (2010m; + chapel; *** fork paths to Grand Vaudala(z) Walloon) and immediately after a winding road North/South to following Barmaverain Pasture (2037m). Continue through false level route with a long diagonal in South below the waterfalls (2051m) and subsequent (2087m); crossing Roman Bridge, by dirt road also with a shortcut of path to Benevolo Refuge (2280m), above Lavassey Pasture (2227m; (F+; 3h '30/4h '15).
2)- Exceptional Via n° 1: from Refuge go before South and, crossing two stony small bridges on Rhêmes Doire, after change twice Northwest/South passing Sauches Alp (2313m) and following fork (2420m; in South path to Granta Parei/Tsantàleina Lakes); from cross instead tourning Northwest to overhanging rocky pomontory (2615m; in South Normal Route to Granta Parei). Abandoning this last, continue on small path in Southwest reaching the effluent of Goletta Loch (2698m). Doubling North the same e with route always Southwest, climb amongst moraines below South Face of Pointe Bassac Déré (keep a suitable distance due to the danger of falling rocks); reaching a zone more steep to cross towards a small trace into a serie of blocks and boulders rotten and broken. The subsequent slope should be carried out zigzagging between them (source hidden into rocks) and with a short traverse to the left to reach a small plateau, usually snowy. To cross with diagonal ascent on Southern border up to the final part under the pass; through an easy track to Bassac Déré Hill (3082m); continue South on watershed Rhêmes/Valgrisenche and, through traces on North Ridge, after two Quotas (3191m, 3158m) to Becca of Traversière (3337/8m) (D-; 4h '30/5h '15).
3)- Minimum Route n° 1: from Rhêmes Notre Dame (1723m) with Municipal Road in South to winding road 1901 metres (stony fountain) neighbor Thumel; from this to Barmaverain-Saint Pantaléon (2010m, 2037m) Alps through dirt road in West (better) also path more in East and above Rhêmes Doire (T; 1h '30/1h '45; 2h '00 on dirt road).
4)- Intermediate step n° 1: from Thumel, with three previous routes, to a first series of Waterfalls (2051m; E; 1h '45/2h '15. Note: from Alp avalanches danger; requesting the snow is transformed), just after Barmaverain Pasture.
5)- Intermediate step n° 2: from shelter through path to rocky promontory 2615 metres and following Goletta Lake (2699m), under Glacier and North Face of Granta Parei (3387m; F+; 2h '45/3h '15; same preceding remarks).

6)- Exceptional Via n° 2 (Granta Parei Tour): from refuge to fork 2420m; continue South reaching before the small Granta Parei Lake (2576m). Crossing the effluent and doubling West Truc de Tsantelèina (2640m) to rocky promontory 2706 metres before with path, after through a small trace less and less evident amongst the boulders; climbing on debris reach the point 2706 metres just above Tsantelèina Loch (2699m), below the vertical East Wall of Granta Parei. Passing over Western shore, through blocks and moraines, to reach the Tsantelèina and Sauches Glaciers. With delicate traverse on the same and bending more Southwest to Tsantelèina Pass (3154m), between Pic Goletta/Tsantelèina Summits (M+; 4h '15/4h '45). Descent: before in Northwest on Rhêmes-Golette Glacier, after in North crossing completely the Northern Golette Glaciers bending Northeast below Granta Parei West and North Faces and above Goletta Lake; reached the Standard Route of the same to the base of the Northeast Ridge, with preceding routes through traces-path, to Benevolo (see the two next B&W pictures; F; 3h '00/3h '15 from pass to refuge.
*** Special footnote: all the aforesaid crossing glaciers requires extreme caution, especially so for those to be carried down; this tour is not open to all and requires experience and knowledge of glaciers to a certain level; also sometimes, it is not practicable due to the state of the glaciers; in this situation is preferable return with same via.

7)- Intermediate step n° 3: from shelter to point 2756 metres just over the Northeastern emissary of Goletta Lake; from this to Bassac Déré Pass (3082m), between Becca of Traversière/Bassac Déré (3353m) Summits (M+; 4 '00/4h '30. Remark: this path can be considered a variant of the previous shortened route; typically is the busiest via).
8)- Variant n° 1: from Thumel, leaving South the path to Shelter, crossing small wooden bridge on Dora Rhêmes (splendid canyon) and through a subsequent footbridge, through small path neighbor a series of waterfalls, to overcome the first ramp into forest; after a very narrow gorge and getting closer and closer Vaudaletta Torrent reach an alternative (2500m; in East to homonym walloon to Leynir Hill 3084m, below Taou Blanc 3438m) nearby Vaudaletta(z) Alp (2443m) and under the Forest Rangers P.N.G.P. Cabin (private; 2480m); F+; 3h '00/3h '15).
9)- Variant n° 2: from fork just before Saint Pantaléon Alps (about 2005 metres), crossing twice on small bridges up Dora Rhêmes and Vaudala Torrent, through path zigzagging in Southeast on Vaudala Walloon to Grand Vaudala Alp (+; 2338m) at the entrance upper part of walloon (in East-southeast path along the torrent and following walloon to Rosset Hill 3023m, between Leynir 3230m/Rosset 3100m Summits; E; 2h '50/3h '10 from Thumel).
10)- Exceptional Via n° 3: from refuge through path in South-southeast and towards Basei Desot and Damon Pastures (2309m, 2412m), crossing various small walloons, to promontory 2429 metres over the sources of Doire; bending more Southeast and crossing two secondaries torrent below Gran Croux (2720m), with diagonal route amongst other height torrents and brooks reach the altitude 2707 metres. From this, decisively East-southeast route above Northern flank of Lavassey Glacier, to fork around 3020/30 metres under the two passes; in Northeast through path to 1)- Nivoletta(z) Pass (3130m). In Southeast through not always too obvious traces and very rotten blocks to 2)- Basei Hill (3176m); from this through North Crest (better to remove snowshoes), crossing the Quota 3196 metres, to terminal part. Doubling left (Est) and overcoming a small wall (exposed and equipped passage) towards final part of ridge to Basei (+ great Cross; 3338m; D+; 4h '30/5h '15 from refuge; F; 8h '00/8h '15 from Thumel).
11)- Exceptional Via n° 4 and Variant n° 3: from Basei Pass to 1)-, with traverse on watershed Rhêmes/Nivolé Tableland, to Nivoletta Pass and neighbor Southern, Northern Summits (3163m, 3209m; M+; 1h '00/1h '15). Variant n° 3: also from fork around 3020/30 metres through semicircular route Northeast/Southeast to pass and subsequent preceding route on enough easy South-southwest Crest. Possibility, good conditions, combine the pathways, but keep in mind that the hike is already very long for one of the two peaks: high degree of training required.
