Those interested in trekking in India can choose from a broad palette, from relatively easy one-day treks to multi-week treks to winter mountain expeditions. Those interested in easier treks can consider trips through some of the mountain valleys that are accessible by car, such as the Kulu Valley in Himachal Pradesh. More challenging treks are easy to find. Multi-day or multi-week treks can take the traveler well away from road, up and down mountain switchbacks, with considerable elevation gain. During longer-term treks, accommodations are normally rudimentary lodges, often with beautiful mountain views.
The Indian Himalayas offer long and short treks at a variety of elevations. For those prone to altitude sickness, elevation may be a consideration. Elevation also affects climate, as higher elevation zones stay cold longer into the spring. While low elevation trek often travel through heavy forest, high elevation treks in places like Ladakh often travel above the tree line, and are generally quite rigorous. In contrast, a trip through the lush Tons Valley in the Himalayan foothills offer the possibility of relatively low altitude multi-day treks.
The Indian Himalayas extend through multiple climate zones, with elevation adding another variable. In the north of India, most trekking companies operate from May to October. Treks earlier or later in the year are available in Sikkim or Arunachal. The northwest will tend to receive more snow throughout the year, with India's eastern Himalayas receiving more rain. The trekking season in Ladakh start the latest, in June, with the best conditions generally in September.
The regions in India have a variety of unique ethnic cultures, from predominantly Hindu cultures in Himachal Pradesh and Uttar Pradesh, to the Nepalese influence in Sikkim, to the Tibetan Buddhist culture in Ladakh. Those considering treks may also be interested in additional activities, such as whitewater rafter, visiting mountain temples or holy sites such as Rishikesh, or wildlife sanctuaries such as Corbett Park. Trekkers should be aware that most treks travel over rugged terrain far from roads, hospitals, and other means of support should a problem occur. Therefore, it is important to plan carefully, find treks at the correct level of ability during the right time of the year and to have basic medical supplies in case of mishaps.
