"An amazing view!!! Follow the path to the marker, then go down the rocks to the right. Take time to enjoy the many other amazing sights besides the blow hole. You will not regret the effort. Wear good shoes."
Jared Hopkins
"A wonderful place to start you hike to the cliffs and blowhole. The parking spots might be limited, but we were lucky that we got a spot in the middle of day in May, close to the road side. The trail was not well marked, so we had to figure out the way as we hike. “Stay as close to the sea but not too close to the cliffs” was the advice given by a returning hiker, and was proved to be wise through our own experience when we started hiking to the first portion. The view is unique and marvelous. Definitely worth of your a couple of hours while visiting the island."
Xin Chen
"While the view is spectacular, the trail is not marked at all and difficult to navigate. Sharp, rocky, steep scrambling. We took our toddler, thinking it was a leisure trail, and was a little concerning. Ended up bushwhacking through grass and fields because we couldn't find trail. Trail very exposed on the cliffs. Reco to go early morning or evening to minimize burning sun."
