The unusual geography of this trek gives us two natural ways to complete it.
Indian citizens follow our standard Siliguri-to-Siliguri traverse. After approaching Sandakphu through Nepal, the journey continues through Aahl, Sabargram and Phalut before descending to Gorkhey, Rammam and Sepi. From Sepi we drive back towards Siliguri, NJP or Bagdogra.
International trekkers are normally offered a Nepal-only variation. They can meet us at Bhadrapur Airport, or arrangements can begin from Siliguri where their visa and formal immigration itinerary permit it. After reaching Sandakpur, they continue through Charrate and Phalelung rather than crossing informally into India at the high mountain border.
The Nepal-only journey finishes towards Panchthar and can connect onwards to Bhadrapur. This keeps immigration straightforward while still preserving the essential character of the trek: Ilam, Chintafu, Sandakpur and the remote Phalelung highlands.
International borders may look invisible on a mountain ridge, but immigration rules are not. We design the final route around the traveller's nationality, visa type and authorised entry and exit points.
Where an international guest holds appropriate visas and the required formal border movements are possible, a Siliguri-to-Siliguri journey can also be planned individually. We confirm those arrangements before booking rather than promising a border crossing that may not be legally available to every traveller.
The trek is best suited to reasonably fit walkers comfortable with consecutive mountain days, basic local accommodation and changing weather. March to May brings flowering rhododendrons and greener forests, while October to November generally offers the strongest combination of stable trekking conditions and clear Himalayan views.
Whichever ending is used, the purpose remains the same: to experience the Singalila landscape as a continuous Himalayan journey rather than simply reach Sandakphu by the shortest possible route.
