Spouting Horn is interesting itself, but what I found more interesting was the waters around Spouting Horn. Each time I was there I saw large Sea Turtles. There are also, merchants there selling their wares, like neckless and ear rings, and lots of other stuff. This is a nice place to stop. you won't send a lot of time here.

we went driving from our hotel and ended up here about 10mins from poipu, cool to see the spot, for like 10 mins then moved on. great views of the area

The blowhole isn't really all that exciting, but maybe that was because I've seen many others and I could actually walk up to them. But, it's worth stopping off. What makes it worthwhile is that it is an excellent spot from which to spot whales during whale season. We spotted four! That made it all worthwhile.

It was ok. Easy to get to from Poipu. A good thing to do on my first day or make a side trip to. But wouldn't spend all day trying to get here.
