I went to Maui this January and stayed in the Kaanapali area. Very touristy side of the island, but the beaches and sunsets are amazing so great ocean photography.
My favorite food place was Leoda’s Kitchen and Pie Shop. Great food and quick for take out.
Iao Needle was a great hike with lush mountains and streams. Nakalele Blowhole on the far north of the island was a pretty drive and there’s a local guy who makes and sells the most amazing banana bread ever.
I wish I had spent more time in the upcountry - I did a quick drive through there but I would definitely return to explore next time. And of course, the road to Hana is the best place for lush greenery and waterfalls. But very crowded and touristy.
The best big surf is on that side of the island - Ho’okipa Beach is famous. I heard that Mama’s Fish House near Paia is amazing (and reservations are a must.)
Whatever you do, it will be amazing. It’s so beautiful. Have fun!
