Day by Day Breakdown
Drive: Dehradun to Sankri
Pick up at 7:00 AM. Guesthouse stay. Use this day to register with the Forest Dept. Technical: A massive drive through winding river valleys. The Netwar section is the transition from standard villages to the tribal Supin valley. Avoid heavy meals before the Mori-Sankri hairpins. Safety: Final gear check in Sankri. If you are missing microspikes or a headlamp, buy/rent them in the village market tonight.
Key Landmarks
Trek: Sankri to Seema (via Taluka)
First night in tents at Seema. Excellent for river-side acclimatization. Technical: Level trail along the Supin river. Mostly dusty path but some slippery sections near river bridge crossings. Keep a steady pace; save energy for the 14k+ gain later. Safety: Taluka road is landslide-sensitive. If blocked, expect to trek on the road. Keep rain-covers handy.

Trek: Ruinsara Tal to Odari (Rock Cave)
The 'Col' (Pass) is now visible. Nervous energy at camp is common. Technical: Short but steep distance. Moving across glaciated boulders. The 'Rock Cave' acts as a wind-deflector for the camp. Cold winds are constant here. Safety: Temps drop to -10C at Odari. Check for symptoms of AMS (HACE/HAPE) before sleeping. Descend back to Ruinsara if necessary.

The Crossover: Base Camp - Bali Pass - Lower Dhamni
Reach Lower Dhamni by 4 PM. Celebration of survival and summit! Technical: Summit push is on hard snow. The crux is the descent towards Yamunotri: A 60-degree drop on snow/scree. Ropes and microspikes are mandatory. Don't look down; focus on your footwork. Safety: Descent Alert: 80% accidents occur here. Never descend alone. One slip on the scree requires an immediate self-arrest (Ice-axe/Poles).
