Goa Carnival is India's only Carnival celebration, introduced by Portuguese colonizers and held before Lent. It features parades, music, dancing, and street festivals, reflecting Goa's unique Portuguese colonial heritage. Assam, Kerala, and Kashmir have their own distinct cultural festivals but no Carnival tradition. The Goa Carnival typically occurs in February or March and attracts tourists from across India and abroad, making it a signature cultural event unique to Goa.
