Akuhini is a good dive for intermediate or advanced. Not so good for beginners as vis inside the breakwater/bay is nil and not a soft sand entry. I personally found entry very easy though: Always check out the general area, conditions, surf, swell, entry path, entry point before gearing up for any shore dive. At Akuhini there's a small clump of trees about 20' south of the break wall right at the edge of the parking lot and rocks. Just to the left of these bushes is the best way down over the rocks to the water. Look for the round post (for ship tie-up?). It sits on a flat concrete base. Just to the left of this base is a relatively flat black lava rock which is perfect for donning fins and giant stride entry into about 8' water. Be sure to have your BC inflated so that you don't hit bottom. Again go down and scope it out first, you'll see it. Surf was very high that Mid-April day, many times crashing over the break wall. But that wall made a very calm bay/entry point. I surface swam the 100 yds west past the end of the break wall to the swells entering the bay. After taking compass bearings (the wall/shore here runs nearly due east/west with shore to south) I submerged through nearly zero vis to the 30' bottom under the swells/waves. Perfect, no sweat! Swam directly north & vis greatly improved to 30'-50' in a few yards. The reef was just to the east/right with its edge running north/south. Swam north along the edge of the reef. Look for the large anchor chain and later a LARGE old fashioned double hooked anchor from some old ship. Fish life was good. I stopped and a sea turtle swam right up looked me over the went on about his business. Saw turtles on the surface inside the bay after I exited. Overall a very good intermediate level dive.
