When I visited Dusun Semilir, all I could enjoy was the Rainbow Slide. If you're bringing small children, you might be satisfied with the kids' playground. A place this large should have more places or rides.
Oh yeah, what I think is good is that before and after entering, there are souvenir shops with standard prices. Usually, souvenirs at tourist attractions are a bit pricey. Well, at Dusun Semilir, the prices are standard. Keep it up 👍
