I did a preview trek two days back and trip log + some photos are
here: http://usandeep.com/trekking/kalladi.html
We can plan a camping @ Swargakkunnu if there are atleast 3 people.
Schedule like this:
Saturday morning @ Thamarassery (overnite bus from Bengaluru)
Take a bus to Muthappanpuzha
A dip in the river, breakfast at a local hotel, pack lunch and get
ready from Josettan's place
Trek upto Swargakkunnu and reach there by noon
Camp and cook/campfire overnite
Next day morning trek towards Kalladi
Get to Kalladi by eve and to Meppadi by bus/jeep
Return to Bengaluru by overnite bus (one or two guys may need to go to
Kozhikode and board the bus from there. The rest can take a room here)
We can actually get an additional person to carry some luggage till
Swargakkunnu so that we need to carry less. Lemme know if anyone is
interested
