Why travel to Coorg or Chikmagalur wen it's affordable n accessible nearer to Bangalore? An excellent farm amidst coconut plantation. Get to see the real world agriculture and it's practices. Depends on season for activities such as Bullock cart ride, tractor ride, fishing, boating, walk through the farm. If you're lucky enough you could spot wild peacocks, boars, deers, dholes. Temp wise cooler during winter n warmer during summer. Catch the kokkarebelur bird sanctuary nearby.
Good place for trekking 2 hills in the vicinity.
