Other nations are envious of the Himalayan Kingdom of Bhutan because it is the only carbon-negative country in the world, has never been subject to foreign rule, is ruled by a monarchy, and is populated by ecstatic people.

Following the outbreak of COVID-19, the Bhutanese government, which has a firm grasp on the tourism industry and foreign relations, imposed strict regulations on travellers. Now, Bhutan has loosened restrictions to attract tourists from around the world. The new policy makes it more affordable for travellers to spend more time in the Himalayan nation.

In an effort to attract more travellers, Bhutan has relaxed regulations regarding the payment of the Sustainable Development Fee (SDF), which was increased from 65 dollars to 200 dollars per day last September. And this SDF reduction will continue until the end of 2024.
If tourists pay the SDF for one week, they may remain in Bhutan for an additional seven days without paying the charge. In addition, payment of SDF for 12 weeks will result in a fee waiver for the subsequent 18 days.

Additionally, the website announces that the new programme will begin on June 1. The Bhutanese Immigration Department has also established methods for calculating the amount of money conserved by tourists through various incentive programmes.
