Mookini Heiau and Kamehameha Birthplace Trail is a 2.5 mile lightly trafficked out and back trail located near Hawi, HI. The trail is good for all skill levels and primarily used for hiking. Dogs are also able to use this trail.
Maybe you could drive it because it's not super rugged, but I'd stay safe and walk unless you have 4-wheel drive. Luckily it happens to be an easy walk that has the ocean right next to you.
