2022 update: Porta-johns now gone. :( Cute park with parking and porta-johns. It's the entrance to Kawainui Marsh Trail. Great, easy, mostly paved (some areas are gravel) and pretty flat hike along Maunawili Stream.

Fine if you live nearby or are driving past, but not ideal for biking and definitely nothing to go out of your way for. "Bike Trail" is a misnomer. It's about two-thirds (across) gravel not suitable for biking, and a bit of paved road (after a stretch towards the beginning that's all gravel). There are signs saying pedestrians have the right of way, and they will. not. move. for cyclists, so passing is tricky, stressful, and generally annoying.

There's plenty of parking. There are two fairly nasty portable toilets by the...
