Though there are many places of interest at Mount Abu but other than that Trekking/Mountaineering Institute/Meditation Centre in Mount Abu I found also exists within the hill town and nearby location.
Harvinder Singh (Harry) is one such person who organizes trekking. Once you reach M. K. Circle and walk towards Nakki Lake (approx. 50 meters) you will find his shop on the left-hand side. Either he himself will join you for trekking or will arrange someone for you. And charges I find economical.
I did two treks. One was the Trevors Tank trek close to Dilwara temple about 1 hour 30 minutes trek passing through Trevors Tank > Abu View Point (122 steps) > Valley View Point (63 steps) > Crocodile Point > Wild Watch Hut > Valley of Death Point > Mini Nakki Lake and finally ending at Chimney.
The second one was Lakh Chaurasi > Sone Singh Cave > Upper Kodra Dam and finally Gaumukh road. Approx. One hour 30 minutes trek.
If you want to know which was the best trek I have to say both were the best. Reaching Upper Kodra Dam is tiresome a little but once you reach the very first glimpse of Kodra dam and clouds touching silent water – amazing to watch.
And how much I pay?
I was the only one with the trekking guide. I paid Rs. 300 for each trek.
Other than trekking once while passing through Arya Samaj Road, nearby Nakki Lake I saw rock climbers. I inquire and my knowledge was enhanced by one of the present instructors. They are from Swami Vivekanand Institute Of Mountaineering, Gaumukh Road, close to Gujarat Bhawan where one can take admission to join various mountaineering courses.
Adventure Camp, Gaumukh Road – During the trek of Upper Kodra Dam while ending and coming towards the hotel I saw another display board talking about conducting various activities such as rock climbing, repelling, horse riding, night trekking, boating, and more…
And Meditation at Spiritual Research Institute (Sambodhi Upavan), Gaumukh Road, Mount Abu. I met Mr. Surane. I was told about various upcoming meditation courses. Currently, all seats are full but yes, for October one can write to enroll. The institute location is excellent – very peaceful.
In short, will say: Mount Abu is not only a hill area with a cool green environment within Rajasthan but also a location for trekking, mountaineering, and meditation. One should visit once.
