Hi Somya, Gokarna is just best for relaxing and taking a break from urban life. There are so many local vendors who can provide you camping on beaches (under different budgets). The camps are equipped with basic amenities and provides food and bonfire also. You can checkout camping facilities provided by Gokarna Adventures, Shiva Camping Resort, Trippr Gokarna, White House Beach Resort. Budget may vary according to services and quality of camps you want to stay in. Have a memorable weekend!
