Mountain biking on the Old Silk Route
A high-altitude mountain-biking experience along the historic Old Silk Route near Zuluk (Dzuluk) in East Sikkim. Riders follow the zig-zagged ridge roads and the winding 'Old Silk Road' stretches that once linked India to Tibet, passing high-altitude meadows, rhododendron forests and dramatic vistas of the Kanchenjunga range. The trail mixes packed dirt, gravel and rocky stretches with several steep climbs and fast descents, offering both technical riding and unforgettable scenery. Typical altitudes range from ~2,800–3,600 m (9,200–11,800 ft), so acclimatisation is important.

Safety Requirements
Good aerobic fitness and previous off-road cycling experience recommended
High-altitude precautions: allow 24–48 hours for acclimatisation; watch for AMS symptoms
Full-face or sturdy helmet, gloves, knee and elbow protection, and layered clothing for temperature swings
Reliable bike with at least front suspension (hardtail) or full-suspension for rough sections; tubeless tyres or spare tubes and a pump/CO2 kit
Permits/permissions: some border-proximate routes require local permits arranged by tour operator (carry ID - passport/Indian government ID)
Vehicle support or a competent guide with local knowledge is strongly recommended
Emergency plan: oxygen canister availability, first-aid kit, charged mobile power bank (network can be intermittent)
Tips
Acclimatise in Gangtok/Rongli for a day before heading higher; drink plenty of water and avoid alcohol on the first night.
Use a bike with low gearing for long climbs; wider tyres (2.1"+) give confidence on loose gravel.
Pack windproof/waterproof layers — weather can change quickly above 3,000 m.
Carry cash (INR) and limited personal medications; ATMs and card acceptance are sparse in remote East Sikkim.
Book local guides and permits in advance during the high season; support a local homestay to benefit the community.
Respect restricted zones and Army checkpoints — always follow guide instructions and carry ID.
Leave no trace: take all litter back to villages and do not disturb sensitive alpine vegetation.
