Hiring a porter and guide for the Manaslu Trek and Tsum Valley is a practical and culturally enriching choice. To find experienced and reliable assistance, start by considering a reputable trekking agency based in Kathmandu or other major cities in Nepal. These agencies typically have well-trained guides and porters on staff and can arrange everything for you. Alternatively, you can conduct online research on which often feature recommendations and contact details for guides and porters. Local recommendations from fellow trekkers, guesthouse owners, or residents can also be valuable.
