In the following Article I am trying to provide the list of places which are close by and can be covered in a day trip.
Some words of caution:
1. Though the places would be interesting, the locals and the villagers are a bit apprehensive about people meddling with the peaceful lives.
2. Understanding and speaking Kannada would be advantageous. Many people do speak broken Hindi, English, Tamil and Telugu, but it is easier to deal with them in Kannada.
3. DO NOT indulge in drinking in these places. Not only you may get fined heavily, but also the place can be sealed off and made unavailable to any others to are interested to visit them.
4. There could be restrictions regarding visiting. For example, there are reports of people trekking to Skandagiri during night (as far as I know, there's a ban on trek at Skandagiri) and getting caught by police. So please verify before visiting any place.
Here comes the list:
Madhugiri - The second largest monolith hill in Asia. One can trek to the top of the hill where the ruins of a fortress can be seen. The trek is a bit hard, and can a test for your fitness. On an average, one would require around 2 hours to trek from the foot to the top.
Distance: 100 km
Chennarayana Durga: Located on the way between Devarayana Durga and Madhugiri. Can be trekked to the top.
Distance: Around 80 km
Thattekere: Located on the farther side of Bannerghatta forest area, Thattekere is a very calm and relaxing place, and is unknown. The route itself is very scenic.
Distance: Around 40 km
Huliyuru Durga: I haven't been here. But several blogs say it is a relatively easy climb.
Distance: 85 km
Makali Durga: Another short trek
Distance: 70 km
(OK, enough of hills and treks!)
Janapada Loka: On Mysore Road, a few kilometers after the town of Ramanagara, you can find this place on your right. The word JANAPADA in Kannada means folklore, and this place is a folk museum and is the brainchild of Sri. H. L. Nagegowda, a famous folklorist and a civil servant.
Distance: 55 km
Kabbala Durga: An unheard place in a remote location. I'll leave the fun of finding this place to you :-)
Distance: 85 km
