This trek is a combination of Manaslu High Circuit, with Tsum Valley and Larkya Peaks (Sano & Thulo).
Challeging but satisfying, Thulo Larkya Peak can really test your endurance.
Generally, people first climb Sano Larkya and if they think they actually climb Thulo Larya, they go for it.
Anyone with a good fitness level can do the the Manaslu High Circuit combined with Tsum Valley but to add Larkya Peaks (Sano & Thulo), you ought to have some serious climbing experience.
Although this trail was affected by the earthquake, it still is a fantastic option for camping trek.
