Kaiwainui Marsh has a long winding paved walkway that goes through an expansive marsh. We saw many ducks and birds today and caught the light of the magic hour at sunset. The light on the water was magical and so inspiring. It is a secret spot on Oahu well worth the visit. I lived in Kailua for a year and this was one of my favorite spots. It's great for running or walking and the there is a dog park at the entrance so you will experience lots of dog happiness energy as you start your journey.
