The trail is hard to find because there is no sign for the trail but if you follow this simple instruction you'll not be lost.First park at Halona Blowhole Lookout then cross the highway then follow the rail, at te end of the rail you'll see a big rock on your right, keep on walking then if you see the end of the rock from their you can climb the rock and on top of the rock you'll see the trail head going up to the arch. You will not missed it, it's on your right side. You'll have to have a good pair of shoes ( hiking shoes if possible ).
