Anyone think in Malaysia unless you work near special areas like Diving site o beach there's a lack of special activities?

Most activities available during weekends usually Shopping, Cinema, Golf, Themeparks, Casino, General Sports, Food & Drink I think sums it up. These are generally General activities for the whole family, but not for you.

Since Malaysia is hot weather country i'm not expecting snow boarding/skiing on Mt. Kinabalu, but still got many other things not involving snow.

For example many countries like US/Aus/Japan has lots of race tracks for weekend drivers to fulfill their adrenaline needs, they just need to drive next town, here there's only Pasir Gudang & Sepang + some no name circuit where people rarely organize anything for public, so car clubs have to use public roads to organize events. If race tracks are too expensive, you rarely see any Go-Karts no more, there used to be some but seems either they charged too expensive or typical Malaysians just not interested but in many countries they are affordable you can even buy your own karts. If a Gokart circuit is still too expensive, can always ride dirt bikes in the Forests.

Beaches, Malaysia full of beaches, yet there's only a handful of beaches that actually suits beach activities like Penang & Sabah/Sarawak, places like JB has a good beach location yet it's designed for Look Sea only and the closest beach Johoreans have is Sentosa beach. In US almost any states along the seaside will have a proper beach for outdoor activities, malaysia have to pay & go to Sunway Lagoon or Desa Water Park...

Fishing, fishing ponds near non-existence now, used to be a cheap & peaceful way to pass time. now you have to drive to Kuala Selangor or somewhere remote, or be hardcore & rent a boat and go into the swamp areas, still possible but need to be hardcore enthusiasts.

Cycling, a very common  sports, but cycle lane is no where to be seen here. There's no place dedicated for cyclists like Singapore has. Even Langkawi which hosts Tour de Langkawi don't really have much cycling activity when there's no Tour de Langkawi.

Then we don't need to talk about other more expensive stuffs like yatching, horse riding, water jet packing, you may be able to find them in Penang & tourist hotspots which is 500km away..

these just few examples. even though some exists, they don't last long due to lack of support from locals, lack of tourism in major parts of Malaysia, and expensive price that people rather do the same thing over & over like shopping. but not bored meh? weekend even you have car also don't know where to drive to, drive all the way to Genting/Kuala Selangor also just to eat/gamble, drive to Seremban nothing to do, down to Melaka also eat only since most tourist place you usually go 1 or 2 times at most, even up to Penang, just Gurney Drive & eat & go to temple. even temple malaysia only got so many to visit. they should really make unique Mosques so it can become a tourist attraction like how people keep visiting temples after temples in China & Japan.

I think Putrajaya actually has lots of potential to become the weekend escape for KL people. It has the land, road & facilities to support, well until one day Putrajaya becomes overcrowded. Even if there's already one, most people probably never heard about it just like other White elephants.

But I'm guessing Malaysians so used to the hot weather they couldn't be bothered doing outdoor activities. But why is Sinkie different?

The problem is when something new comes up, they always ask for skyhigh price, it becomes not-so affordable and less people go, they lose money, close shop and people call it a day for that type of activity because they see how previous business tried & failed.

but you can choose:

1.Beach Volleyball
2.Boat Skiing
3.Sunbath
4.Build Sand Castle
5.jetskii
6.chilling out
7.baywatch

you are bored because Singapore has limited land, they can only offer you so much, but malaysia so big, yet so little things.
