The most famous temple in Gujarat that is the Somnath mahadev temple is close here and so if you are in this part of Gujarat, you have to visit it. We were a bit out of schedule but i would suggest one to reach Somnath temple early in the morning. The spiritual experience that you have there is something i am a huge fan of. After visiting the main temple building, you can relax in the temple campus which is also a sea-view so just sit there and relax for sometime and enjoy the calmness. Also there are various mythological descriptions inside the temple campus. If incase you reach this temple on the evening, a light and sound show will welcome you to the temple after the evening aarti. (As no phones and cameras are allowed in the temple campus, i only have shots from outside the campus).
From Somnath, we moved to Diu which is about 50kms. Diu is an island city which still has the essence of the Portuguese community that lived here pre independence. Diu can be termed as the Goa of gujarat. It is a very beautiful city. It is calm, has pleasent climate, good food, and for the gujaratis, ALCOHOL IS LEGAL HERE. The place is a heaven for anyone who wants to chill, get relaxed and away from their busy usual schedule. Also it is not very expensive so living here for a few days is a good option. The city has a beautiful Fort, caves, churches, many beaches and some very cool restaurants and cafes. Just get a speaker and some food, some beer, go to a beach with your friends in the evening (try jalandhar beach as its a quite place) and have some dinner with music. A very magical thing to experience.
