Beach Cleanliness Criteria
The department evaluated Thailand’s beaches according to the following four criteria:
- Plastic and oil pollution and residue;
- Coastal and beach trash management;
- Condition of reefs and national park resources;
- Environmental control, and tourism management.
Not surprisingly, none of Thailand’s cleanest beaches are lined with five-star resorts.
Does the lack of well-developed tourism infrastructure have anything to do with the high rankings of Thailand’s cleanest beaches?
In fact, many of these beaches are within national parks. Not only are these beaches well-managed.
In addition, they are closed off during the off season. Therefore, the natural environment can rejuvenate itself.
Cleanest Thailand Beaches
Other beaches can only be reached by the occasional ferry. You might even have to rent or charter boats to reach some of them.
Accommodation ranges from simple hotels to guest houses to campgrounds to homestays. At some of them, there are a few bungalows with bathrooms, air conditioning, hot water, and televisions.
Will you be able to stay online and post selfies?
Generally speaking, don’t expect infinity swimming pools, lavish buffet breakfasts, and cocktails on the veranda at sunset.
For the intrepid ecotourist, however, exotic flora and fauna, stunning scenery, fantastic snorkeling, amazing treks, and a chance to reconnect with nature – far off the well-beaten tourism track – awaits.
