At only, it is a small park that is only open during the daytime. It provides picnicking facilities and restrooms, but there is no drinking water. Fishing is allowed but swimming is discouraged due to the rocky shore and cliffs and strong currents. A hiking trail follows the old Hawaiiancoastal path, "the King's Highway", and passes the mouths of lava tubes. The park contains the largest grove of ironwood trees in Hawaii which were planted in the 1930s by ranger Albert J. MacKenzie, who after his death at age 21 became the namesake of the park. The park is considered part of the Malama Ki Forest Reserve.
