The cheapest way to travel in Dubai is the Dubai metro - one of the most advanced metro systems in the world. There are other public transport options such as taxis, buses, monorail or water taxis. Call Dubai taxi to book a ride or if you prefer app-based cab rides then go for Uber or Careem. You could also rent a car if you feel like driving around. Opt for hop-on hop-off bus if you want a city tour or go for regular buses. Buy a NoL Smart card for both bus and metro rides.
