At Somnath, your Hotel guys will help you patch up with an auto rickshaw that'll take you around the perimeter, at different spots. it's typically a one evening excursion. Mainly temples and places of religious/spiritual significance.
It's more convenient than taking your own vehicle.
They typically take about Rs. 500/-
The next day you can do the abhisek at old Somnath temple. the kind of abhisek you choose depends on how much you're willing to pay for it. There are plenty of pandits near the entrance of the Somnath Temple. Pick one that you are most comfortable with. Dwarka is lovely. The temple is magical. Though, I'd recommend going there well before sunset. Morning time is the best.
Bet Dwarka has an old world Heritage like charm.
You'll also get 'Gomti-Chakra' for about Rs. 5/piece at road side stalls. They sell in Mumbai for about Rs. 75 / piece. They are believed to change ones fortunes and bring one good luck. Enjoy your Holiday. God bless 😇
