Wake up to watch the sunrise before the tourists arrive!
Since the big resorts are on the opposite side of the island, most visitors to Maui travel the Hanna Highway as a day trip. Camping on the eastern shore along the highway at Waianapanapa State Park means you get to wake up early, watch the sunrise, and get a start on your day's adventures before the rest of Maui's visitors arrive for the day.
The location is the best thing that Waianapanapa has going for it. It's a pretty basic campground which looks more like a park set right along the coast. There's some small beach inlets you can explore, but it's mostly lava rock and cliff with the campground set up high.
You'll need a permit to camp. The cost is $18 per night for up to 6 people, and there is a discount if you're actually from Hawaii. You can get the permit online and you'll need to print it out and attach it to your tent once you arrive. The process is super easy but requires a little bit of pre-planning.
There aren't many (if any) actual sites- but there are a few grills scattered around that people tend to make camp around. We picked a "site" near a couple of trees so we could sleep in our hammocks of course. The campground does have bathrooms and cold outdoor showers.
My favorite part of camping at Waianapanapa was waking up in the morning to watch the colors of the sunrise and then exploring the park while it was still pretty quiet. There are blow holes, lava tubes, some caves you can swim in, and a hike up and around the coastal cliffs. And of course, there is everything else on the Hana highway just a super short drive away.
