Happened to go on 2 treks in the last 3 weeks. Both in the Western Ghats, around the Charmadi Ghat region. The first one was to a mountain named Amedikallu near a town called Shishila. Shishila is ~20 KM from the holy place of Dharmasthala. The trek didn't involve covering much distance, like Kumaraparvata. But was real steep & extremely tiring. And things don't get better if one gets multiple bee stings, do they? It is one trek I would definitely think more than twice before attempting again.
The second one, more recent was from Durgadahalli (the village of the fort) to Ballalarayana Durga, to Bandaje falls and terminating at Mundaje (near Dharmsathala). Ballalarayana Durga was built by Ballala Raya (as the name suggests), but apprently was later captured by Tipu Sultan. The trek was via Bandaje Falls. About 600 feet high. The view looking down from the top of the falls was awesome.
The trek was planned so that it would be mostly climbing down. So it was not tiring. But as usual, the ankles and knees took a severe beating.
