Sikkim is better known for monasteries and mountain views than for adventure sports, but the state has a small set of genuinely good adventure activities — Teesta river-rafting (grade III-IV rapids), paragliding from above Pelling, bungee jumping at Singshore bridge in West Sikkim, mountain biking from Gangtok to Aritar, and short ropes-and-rappelling experiences. Most of these operate seasonally and the operator quality matters enormously. This is the local guide to what is genuinely worth doing, what season each works in, what it costs, and who to actually book with.
Teesta and Rangit river-rafting
The Teesta river runs roughly 309 km through Sikkim and West Bengal. The rafting stretches are in the lower Teesta around Melli and Bardang, and in the smaller Rangit river around Jorethang. Grade III-IV rapids in peak season (March-June and October-November). The standard rafting trip is a 2-hour float from Melli to Triveni or from Bardang to Singtam with 8-12 named rapids. Rangit river is calmer (grade II-III), more family-friendly. Operators provide rafts, paddles, helmets, life jackets and a safety kayaker. Cost: ₹1,200-1,800 per person for the standard 2-hour trip.
- Best months: March-June for high water (after snowmelt), October-November for moderate water and clear weather
- Avoid: July-September monsoon (river too high and dangerous), December-February (water levels too low for rafting interest)
- Trusted operators: Bumchu Adventures (Melli base), Himalayan Tunes Adventures (Jorethang base)
- Suitable for: ages 12+ with basic swimming ability; up to age 60 with normal fitness
- Combine with: Tsomgo permit day from Gangtok, or as a leg on the drive from Gangtok to Pelling
Paragliding above Pelling
Paragliding in Sikkim operates above Pelling, with tandem flights launching from the Bhaledhunga ridge and landing on the lower meadows toward Geyzing. Flight duration: 8-15 minutes depending on conditions. On clear days the flight includes Kanchenjunga views from above the cloud line. The pilot does all the technical work; you just sit in the harness. Cost: ₹3,500-4,500 per person for the standard tandem flight; ₹5,500-6,500 for the "Kanchenjunga panorama" longer flight. Operating season: October to mid-December and March to mid-May. Closed in monsoon. Bring a windbreaker — even on warm days the takeoff ridge is windy.
Singshore Bridge bungee
The Singshore bridge near Pelling is the second-highest bridge in Asia (220 m / 720 ft above the river below). Bungee jumping operations were introduced here in 2019 and have been running seasonally since. Cost: ₹4,500-5,800 per jump. Safety equipment is imported (Australian, New Zealand-standard certified harnesses). Operating season: same as paragliding — October to mid-December and March to mid-May. Age limit 18-50 typically; weight 45-110 kg. Bring photo ID. Walk-in same-day booking sometimes works on weekdays; weekends and peak season need 3-7 days advance.
Mountain biking — Gangtok to Aritar and Old Silk Route
Mountain biking is a small but growing scene. The standard biking routes: Gangtok → Aritar (75 km, 2-day route, mostly downhill), Pelling → Yuksom (35 km, gentle climb-and-descent), and the Old Silk Route from Rongli to Zuluk for serious riders (220 km, 4-5 days, includes the 32 hairpins). Bike rental from Gangtok at HMI Outdoors Centre (₹800-1,500 per day for hardtail mountain bike with helmet, gloves, repair kit). Guided multi-day rides through Bumchu Adventures: ₹4,500-6,500 per day inclusive of bike, guide, accommodation. Best months: same window — October to early December and March to early May.
Rappelling, rock climbing and other shorter experiences
- Rappelling at Bumchu Adventures (Reshi) — short cliff-face rappels, 15-25 metres, ₹650-950 per person, 1-hour session
- Rock climbing at the HMI Tenzing Rock (Darjeeling) — beginner-friendly, ₹450-700 for a 2-hour intro, equipment provided
- Yak rides at Tsomgo Lake — popular but ethical question — see notes below
- Caving at Lhamu Cave near Pelling — small but interesting, ₹250-450 for guided hour-long tour
- Hot air balloon over Gangtok — operating sporadically since 2023, ₹4,500-6,500 for a 30-minute flight (check current status before booking)
A note on yak rides — please skip
Yak rides are heavily marketed at Tsomgo Lake (East Sikkim) and we politely recommend skipping them. The yaks at Tsomgo are tied to the back of pickup vehicles and driven up daily; they spend long hours in cold cement-floor enclosures with limited care. The ride itself is a 100-metre walk on a tethered animal — not a meaningful animal-experience. The same money supports a different kind of tourism. If you want to encounter yaks, the working yaks at Nathang Valley and Chopta in their natural high-altitude grazing grounds are a much better experience — no riding, just observation.
Seasonality summary
- October to mid-December — peak adventure season; all activities running, weather stable
- March to mid-May — second window; rafting on snowmelt high water, paragliding clear, bungee on
- Mid-May to mid-September — most activities closed (monsoon water levels, poor visibility for paragliding, slippery rocks for climbing)
- Mid-December to February — paragliding and bungee mostly closed (cold and wind); mountain biking still possible but cold; rafting water levels too low
