Having witnessed the rise of Miri from simple oil town to an affluent middle class oil town masquerading as a tourist destination, she has since retired and now acts as a tourist spot and as a reminder of Miri's past.
Unfortunately, the petroleum museum next door has now closed and has reincarnated itself as a dinosaur exhibition, costing 10 ringgit. The walk up here is pretty arduous, so avoid it in the middle of the day; the best time to come is about an hour before sunset.
Perhaps take a couple of beers and park yourself on a couple of benches and watch the sun disappear over the South China Sea; there is a wonderful view of Miri from this vantage point. Bring some torches for the walk down or you might find yourself hitchhiking back.
