By virtue of its varied geography and long history, Karnataka hosts numerous spots of interest for tourists. There is an array of ancient sculptured temples, modern cities, scenic hill ranges, forests and beaches. Karnataka has been ranked as the fourth most popular destination for tourism among the states of India. Karnataka has the second highest number of nationally protected monuments in India, second only to Uttar Pradesh, in addition to 752 monuments protected by the State Directorate of Archaeology and Museums. Another 25,000 monuments are yet to receive protection.
The districts of the Western Ghats and the southern districts of the state have popular eco-tourism locations including Kudremukh, Madikeri and Agumbe. Karnataka has 25 wildlife sanctuaries and five national parks. Popular among them are Bandipur National Park, Bannerghatta National Park and Nagarhole National Park. The ruins of the Vijayanagara Empire at Hampi and the monuments of Pattadakal are on the list of UNESCO's World Heritage Sites. The cave temples at Badami and the rock-cut temples at Aihole representing the Badami Chalukyan style of architecture are also popular tourist destinations. The Hoysala temples at Belur and Halebidu, which were built with Chloritic schist (soapstone) are proposed UNESCO World Heritage sites. The Gol Gumbaz and Ibrahim Rauza are famous examples of the Deccan Sultanate style of architecture. The monolith of Gomateshwara Bahubali at Shravanabelagola is the tallest sculpted monolith in the world, attracting tens of thousands of pilgrims during the Mahamastakabhisheka festival.
The waterfalls of Karnataka and Kudremukh are considered by some to be among the "1001 Natural Wonders of the World". Jog Falls is India's tallest single-tiered waterfall with Gokak Falls, Unchalli Falls, Magod Falls, Abbey Falls and Shivanasamudra Falls among other popular waterfalls.
Several popular beaches dot the coastline, including Murudeshwara, Gokarna, Malpe and Karwar. In addition, Karnataka is home to several places of religious importance. Several Hindu temples including the famous Udupi Sri Krishna Matha, the Marikamba Temple at Sirsi, the Sri Manjunatha Temple at Dharmasthala, Kukke Subramanya Temple and Sharadamba Temple at Shringeri attract pilgrims from all over India. Most of the holy sites of Lingayatism, like Kudalasangama and Basavana Bagewadi, are found in northern parts of the state. Shravanabelagola, Mudabidri and Karkala are famous for Jain history and monuments. Jainism had a stronghold in Karnataka in the early medieval period with Shravanabelagola as its most important centre. The Shettihalli Rosary Church near Shettihalli, an example of French colonial Gothic architecture, is a rare example of a Christian ruin, is a popular tourist site.
Recently Karnataka has emerged as a hot spot for health care tourism. Karnataka has the highest number of approved health systems and alternative therapies in India. Along with some ISO certified government-owned hospitals, private institutions which provide international-quality services have caused the health care industry to grow by 30% during 2004–05. Hospitals in Karnataka treat around 8,000 health tourists every year.
