Despite the reopening, visiting the beach won't be the same as it was prior to 2018.
The Thai environment ministry said on its Facebook page that the number of tourists allowed at the site would be limited to prevent damage to the corals and natural habitat restored during the three years of closure.
According to CNN, only eight speedboats will be allowed to dock there at a time, and visits will be capped at one hour, with a maximum of 300 tourists allowed per round, from 10am-4pm daily.
The closure of Maya Bay had been criticised by the sector, given the popularity of Thailand's Krabi province with tourists.
Before the pandemic struck, tourism accounted for 12 to 20 per cent of Thailand's gross domestic product (GDP).
