From Triund one side you will see Dhauladhar ranges and the other side you will have the Mcleodganj with it's scenic beauty that would steal your heart away. If you're a serious enthusiast then you can head towards the Lahesh Cave which is 3550 km And Then Towards Indrahar pass (4316 m) which is again one of most famous trekker's destination.
You can of course go for a bonfire at night, and enjoy the calmness of the night.
Next day, You can leave early morning after a mesmerizing Sunrise. It'll take around 1 hour 30 mins to get down.
When You start your trek, The Galu Devi point, there you find two roads diverging. One that leads to triund, and the other that goes for a waterfall. you can also have this short adventure.
If not then, Get back to have a trip towards dal lake but It's not really well maintained and clean. So if you have time and you have planned a longer trip than you can make your way towards Dharamkot or towards Kareri village and Kareri Lake which is again a trek but a smaller one.
So, for Kareri, i'll write another blog. But in short, it commences from Ghera village.
Since You've decided Mcleodganj and Triund trek, i wish you happy Journey and enjoy every moment of this trip.
Life is short! stay happy, stay safe and travel a lot!! And yes, That's us!! (Me on the extreme Right).
