1. Overview & Trail Geography
The Kasturi Round Trek is one of the best-kept secrets in Himalayan exploration. While hundreds of trekkers annually follow the well-trodden highway to Dzongri and Goecha La, very few venture beyond Dzongri onto the remote, wild loop that swings eastward through the deep, untamed core of Khangchendzonga National Park (KNP). Traversing through the high, isolated basin of Kasturi Orar (4,500 meters), this 70-kilometer wilderness circuit skirts the glaciated hanging amphitheaters of Mount Rathong, Kabru, and Mount Pandim before plunging down through untouched rainforest valleys to the sacred hilltop monastery of Tashiding.
The journey begins in the historic town of Yuksom, the 17th-century birthplace of the Kingdom of Sikkim where the first Chogyal was crowned in 1642. The initial ascent traces the thundering Prek Chu river through subtropical and temperate rain forests of magnolia, giant tree ferns, and towering hemlocks. Passing through Tshoka—an abandoned refugee village where Tibetan prayer flags flutter over mossy wooden shingles—the trail climbs through ancient rhododendron moss forests onto the open alpine grassland ridge of Dzongri (4,030m).
From Dzongri, instead of following the standard northeast route toward Samiti Lake, the Kasturi Round strikes eastward into an untouched, roadless wilderness. The path traverses high alpine scree terraces and glacial moraines beneath the looming precipices of Mount Pandim to reach Kasturi Orar (4,500m). Here, ancient stone rock shelters ('Orar' in local dialect) used by yak herders and traditional musk deer hunters overlook the vast, silent wilderness of the Rathong valley. The panoramic view of Kanchenjunga's eastern ramparts and the jagged tooth of Mount Jopuno from Kasturi is utterly breathtaking.
The descent from Kasturi is a sensational journey through biological history. The trail drops through pristine dwarf rhododendron scrub into the virgin river gorges of Labdang and Sinon, where giant Himalayan cedars, wild orchids, and bamboo thickets show zero signs of commercial tourism. The trek culminates at Tashiding Monastery, universally revered as the spiritual navel of Sikkim, where sacred water (Bhumchu) has been consecrated for over three centuries. Combining high alpine drama with deep biological and spiritual immersion, the Kasturi Round is the definitive connoisseur's trek of Sikkim.
