I’ve been to Ubin countless times and even camped overnight there with my girlfriend on the various beaches.
Sometimes, there is only us at the beach while camping.
And we have cycled through the regular bike trails as well as through the rugged paths.

There was an incident a few years back when a lady lost control of her bike, hit her head or something and died. But it was an accident, and things happen.

So please don’t go asking people not to visit Ubin.
Ubin is a beautiful and serene place, that I love.

As for respecting spirits, please note that EVERYWHERE you go, the rule of respecting the supernatural world applies. Not just in Ubin.
