Heritage Traveler Tip: Most cultural sites (citadels, temples, and sanctuaries) are concentrated along the Central Heritage Route, easily linked via scenic coastal trains and domestic airports. Natural sites in the north and north-central regions are best explored by overnight cruise or multi-day guided nature excursions.
