Why Coimbatore works for Kotagiri
The Coimbatore–Mettupalayam approach keeps Kotagiri practical for a private Nilgiris package.
For Kolkata travellers, the long-distance connection and the private ground package are deliberately separated. That keeps the advertised 2D/1N, 3D/2N or 4D/3N duration focused on the actual destination tour rather than counting the origin journey as sightseeing time.
