We went on a 3 day trip to Horanadu, Kalasa and Kudremukh from January 14th to 16th.
We started from Bangalore at around 5 in the morning. The route from Bangalore to Horanadu was mostly fine except for the last stretch. We took the following route to Horanadu: Bangalore (NH4) -> Nelamangala on to NH48 -> Kunigal -> Yediyur -> Channarayapatna -> Hassan -> continue on SH57 to Belur -> Chikmagalur -> Aldur -> Balehonnur -> Magundi -> Balehole -> Horanadu. The road from Magundi to Horanadu was not very good although it is very scenic. It is a stretch of about 40km.
You can very easily make out when you enter Chikmagalur district. The place becomes more green, you can see quite a few hills, lakes, areca nut trees, coffee plantations, and the air is cooler and pure. We clicked a few snaps on the way.
