Hi... you can go gadisar lake & vyas chattri in the evening try to see sunset at gadisar lake it's quite close to main city next day you can go to kuldhara village & sum sand dunes. both places in a same way first go to kuldhara then in the afternoon you can visit sum sand dunes see sunset there & if possible try to stay at least a night in the camp site. beware of safari guys (camel walas) bargain with them. if you have more days then you can go to tanot mata temple along with longewala indo pak border . roads are awesome there. cheers & good luck ✌
