There are a lot of easy scenic treks ideal for November. Of course, the Himalaya are the best option, but also consider travelling south for a change of scenery and an equally great experience.
My first suggestion would be to go to Kasol in Himachal Pradesh for the Sar Pass trek. A five-day adventure, this is a trail that goes through the Dhauladhar and Pir Panjal ranges, along snow-capped peaks and evergreen forests.
For a similar terrain, head to Chopta for the four-day Chopta Chandrashila trek, where you will encounter narrow passes and snow-clad forests on the way to the peak.
In the south, there is Araku Valley in Andhra Pradesh. You can walk up to Galikonda Viewpoint, the second highest peak in the Eastern Ghats, and go on to Borra Caves or Katiki Falls. The beauty of the valley and views of coffee plantations are sure to make your vacation memorable.
In Kerala, Wayanad’s Chembra Peak is a steep, three-hour walk to the top. Surrounded by lush forests, the peak has a heart-shaped lake, called ‘hridhayathadakam’, that is rumoured to have never dried up. The trek is moderately easy, but overnight camping at Chembra Peak is not allowed. There are several government and private buses that will take you to Kalpetta, from where you can continue to Chembra. A quick search will help you find operators to assist you with your trek. Check Thrillophilia. There are also several tour operators that offer women-only treks across India. For instance, Gio Adventures organises a three-day trek to Nag Tibba , while F5 Escapes offers personalised itineraries to many destinations.
