This week I hiked a beautiful and cardio focused trail called Kealia Trail.  This trail is located on the north shore of Oahu near Kaena Point.  It is right behind Dillingham Airport.  To get to the trail drive into the airport and park your car in the small parking lot next to the airports tower.  Then start walking towards the mountains from the parking lot.  Follow the concrete and it will be obvious where you should be walking.  Once you get into the vegetation you will see a sign for the trail (see picture).  This trail goes up the mountain for 1 mile.  This is why I referred to it as a cardio focused hike.  That first 1 mile is up switch backs going back and forth across the face of the mountain.  This gives you great views of Dillingham airport below and several beaches all along the north shore.  Once you crest the cliff at the top the trail turns into a road.  This area is called Peacock Flats.  Keep an eye out for peacocks up here.  Keep going across the top of the mountain and at the end of this trail you'll be rewarded with a beautiful view of Makua Valley.  It is breath taking!
