• Thangu Valley– Located 30 km north, it offers accommodation options and is adorned with wildflowers during the summer and monsoon.
• Chopta Valley – A relatively untouched region rich in alpine flora, rhododendrons, and pristine rivers. Known for its religious monuments and biodiversity, Chopta is ideal for trekking, birdwatching, and wildlife spotting.
