Went to Ke'ei this past weekend. The road there is a bit bumpy but go slow and pretty much and car can make it. It is private land so be nice and friendly to all the locals there. The coves offer fantastic snorkeling with decent drop-offs if you enjoy deep freediving. Plentiful aquatic life with lots of eels visible. Actually saw a Yellow margin there that was 6+ ft in length and about a foot in diameter. Definitely the largest eel I have ever seen in Hawaii and it was not far off shore.
