Dwarka
Lord Krishna established Dwarka as his capital 5,000 years ago, just after he left Mathura. Lord Krishna spent one hundred years here. Modern-day Dwarka is a small city located at the western tip of the Gujarat peninsula on the Arabian Sea. Dwarka has a climate that is nice in the winter and not too hot in the summer. It is a peaceful place to stay for a few days.
Dwarka is a Saptapuri, one of seven main holy cities. The others are Ayodhya, Mathura, Haridwar, Kashi (Varanasi), Ujjain, and Kanchipuram. It is also one of the four holy dhamas in India, the others being Rameswaram, Puri, and Badrinath. Sanaka Rishi, Marici, Atri, Angira, and other sages are said to have performed penance here. Archaeological excavations indicate that Dwarka was built on four (some say five) former cities.
Much of the present town was submerged by rising sea levels. Marine archaeologist SR Rao discovered a 250kg anchor, indicating that a 120-ton ship may have used this port. There is evidence to suggest that the city was a large port at least as far back as the 15th century BC. If you are coming to Dwarka for a day trip, you could first visit the Dwarkadhish temple, then take bath in the ocean where it meets the Gomati River, see the Rukmini Temple, and then go for lunch.
You could then go to Bet Dwarka to see the temple there, which opens at 5 pm. Dwarka means door. One of the four original maths (mutts) founded by Sankaracharya is located in Dwarka. Both Ramanujacharya and Madhvacharya came here for pilgrimage.
