One of our favorite things to do with our dogs is find new adventure hikes. We have done many hikes across Maui with the pups (see some of them in the links below). Recently I got out my Maui hike book to look for something new and we realized we have never done the hike to the Olowalu Petroglyphs.
Park at the Olowalu General store. Go to the left of the store (when facing mountain side) and follow the road past the water tanker that goes up towards the mountains. When you reach a fork in the road, stay to the left. The sign was hidden by tall grass and we did not see it until we came back. Look for the small white building structure and follow the road toward the rock wall. There you will see the petroglyphs.
This is a very easy hike. It will take you maybe 20-30 minutes each way. I would recommend going early in the morning or later in the afternoon as the area does get very hot during the day. Don't forget to bring your water (especially if you're hiking with dogs). This is a great, easy hike that includes amazing views of the ocean and mountains, plus the petroglyphs of course.
