Kapaa Lookout

It’s a great spot for whale watching, just don’t forget your binoculars!
We went mid-​Jan, parked easily, and sat out on the rocks beside the parking lot for about 30 min and saw at least 6 whales and possibly a school of dolphins. The spot isn’t super elevated, so you’ll be mostly scanning for spouts then, if you’re lucky, a flipper or two in the same area. If you’re really lucky (which we weren’t) a breach.
There were very few people and plenty of parking when we went (lots of chickens too). There are no facilities and no shade, be warned!
