Naturism in Malaysia isn’t widespread and outdoor nudism is actually illegal. Therefore as a nudist you shouldn’t be nude in public. But it is actually not illegal to be nude in Malaysia in technical terms, the reason is that there is no specific mention of nudism being illegal according to the Malaysian law.
The law says
The Laws of Malaysia, Act 336 (Minor Offences Act of 1955) Clause 28e states it is an offence only for:
Exposure of person with intent
(e) every person wilfully, openly, lewdly and obscenely exposing his person with intent to insult any other person;
Nudists have no intention in insulting other people, and most naturist in Malaysia is mostly private affairs.
Where can you go nude
The Malayan nudists are mostly located in Kuala Lumpur and are conservative.
There are two clothing-optional resorts in Malaysia. They are placed in Hulu Langat and Gombak (Kuala Lumpur). There are also some nude hiking events arranged by Alberty Yan, where the hike goes to Mt. Cheras.
