Riding the Trisuli: Nepal’s Classic Whitewater Between Kathmandu and the Hills
Glacial water, roadside culture, and wave trains—Nepal’s most accessible whitewater run delivers.
The road unwinds from Kathmandu like a ribbon tossed over green shoulders. Terraced hills step upward to the horizon, and the Trisuli River—silver, insistent—keeps pace below the guardrail, nudging boulders and braiding around islets of sand. By the time you reach the put‑in near Charaudi or Fishling, the morning chill has lifted, the river is talking, and the Himalaya’s snowmelt is inviting you in. The Trisuli doesn’t whisper. It hums. It urges. And once the raft noses from shore, it dares you to paddle with intent.
Trail Wisdom
Dress to swim, not to stay dry
Wear quick-dry layers, secure sandals or river shoes, and avoid cotton. You will get soaked; staying warm starts with the right fabric.
Monsoon changes everything
From June to September, flows rise and rapids upgrade to stronger Class III–IV; choose guides who run safety kayaks and be honest about your comfort level.
Protect from the high-altitude sun
Bring reef-safe sunscreen, a cap under your helmet, and polarized sunglasses with a retainer to cut glare and protect your eyes.
Plan the shuttle wisely
Kathmandu traffic can be unpredictable—leave early to beat delays and expect 2.5–3.5 hours each way via the Prithvi Highway.

Conservation Note
Hydropower projects and litter pressure the river corridor—pack out all trash, skip single-use plastics, and support outfitters who practice Leave No Trace.
The Trisuli’s name references Shiva’s trident (trishul); local lore says the god opened the river’s source at Gosaikunda, a sacred alpine lake in Langtang.
Seasonal Guide
spring
Best for: Balanced flows, Warm days
Challenges: Midday glare, Variable winds
March–May brings moderate water levels and comfortable temperatures—ideal for first-timers and mixed-skill groups.
summer
Best for: Big volume rapids, Expert paddlers
Challenges: Heavy rain, Landslide delays, Stronger currents
June–September monsoon swells the river, turning features punchier and raising difficulty; trips may adjust put-in and take-out points.
fall
Best for: Clear mountain views, Reliable levels
Challenges: Popular dates book up, Cooler mornings
October–November is peak season with stable flows, crisp air, and the steadiest whitewater—plan ahead for availability.
winter

Challenges: Cold water, Lower flows
December–February runs are chillier with reduced volume; still fun and splashy, but pack extra layers and expect more rock dodging.

Common Questions
How long is the drive from Kathmandu to the Trisuli put-in?
Most put-ins (Charaudi/Fishling) are 2.5–3.5 hours by private vehicle depending on traffic and roadworks along the Prithvi Highway.
What class are the rapids on the Trisuli?
In spring and fall, expect mostly Class II–III with occasional III+; in monsoon, sections can push into solid Class IV and require stronger paddling.
Can non-swimmers join a trip?
Yes—guided trips outfit you with Type V PFDs and helmets, and guides brief rescue positions. Comfort around water is important; monsoon trips may have stricter requirements.
What should I wear on the raft?
Quick-dry or neoprene layers, secure sandals or water shoes, and a hat under your helmet; avoid cotton. Wetsuits are often provided in cooler months.
Is lunch included on day trips?
Most day tours include a riverside lunch; check your specific booking to confirm. Overnight trips provide dinner, breakfast, and camping gear.
Where do overnight trips camp?
Common camps are on sandy river beaches near Kurintar and downstream; locations shift with season and river levels to ensure safe, comfortable sites.
What to Pack
Quick-dry layers to stay warm when soaked; secure water shoes for rocky banks; reef-safe sunscreen and a hat for intense sun; a compact dry bag with a warm change of clothes for the ride home.
Did You Know
The Trisuli River is fed by the sacred Gosaikunda Lake in Langtang National Park and takes its name from Shiva’s trident—trishul—rooted in local legend.
Quick Travel Tips
Leave Kathmandu before 7 a.m. to avoid highway congestion; bring small cash for roadside snacks or temple detours; confirm whether your operator provides wetsuits in shoulder seasons; plan buffer time if continuing to Chitwan or Pokhara after the run.
Local Flavor
Post-paddle, order dal bhat or a plate of Malekhu river fish with chilies and lemon. Tea houses along the highway pour hot chiya, and Newari snacks like yomari sometimes pop up at roadside stalls. Skip alcohol before rafting—save the celebratory beer for camp.
Logistics Snapshot

Permits: None for rafting. Age: Often 12+; check operator. Add-ons: Manakamana cable car or Chitwan safari.
Sustainability Note
