Hi, Assuming you will start from Bengaluru but not come back to bengaluru Day-1 bengaluru to shravan bela, Hasan floating church halebeedu
Day-2/3 halebeedu to Belur, chickmangluru
Day-4/5 chickmangluru to Coorg to dharamsthala
Day-6/7 dharamsthala to mangaluru My personal opinion Coorg is overrated and so is Mysore
