Just a few minutes south of Honolua Bay on Honoapiilani Hwy, there are a few random parking spots with a staircase heading down to the water. These stairs will bring you down to a protected little beach called Slaughterhouse Beach.
Slaughterhouse Beach sounds scarier than it is, this is actually one of my favorite little spots in Maui. It’s part of the same preserve as Honoua Bay, but it’s a beautiful sandy beach with some fun shorebreak waves. In the winter, the shorebreak can get a little heavy, so be careful. The rest of the months, this is a great spot to swim out and chill with the turtles that hang out here. This spot is a lot less crowded than the other beaches on the west side of Maui.
