Good to know that there are Kudremukh packages organised from Mangalore. I am a Mangalorean.
We had been to Kudremukha trekking last year. It was a wonderful trek, especially on the monsoons. I have written a blog, sharing it here. It might be helpful for those planning for Kudremukha. It would be a good idea to hire a private vehicle so that you can cover nearby places.
