When I landed in Oahu, I expected beaches and sunsets. What I didn’t expect? Just how diverse this island would feel. One day I was hiking lush rainforest trails; the next, I was touring Pearl Harbor or sipping cold brew in a tucked-away café on the North Shore.
If you’re planning a trip and wondering about the best things to do in Oahu, I’ve pulled together my personal favorites—spots that made me pause, breathe, and whisper “Wow.” This guide blends nature, culture, food, and fun, all through a first-person lens. Whether it’s your first time in Hawaii or your fifth, here’s how I’d explore the island again.
🏖️ Relax at Waikiki Beach
Yes, it’s popular—and for good reason. Waikiki Beach is where I stayed my first night, and the buzz of surf lessons, sunset catamarans, and beach bars gave me my first taste of Oahu’s charm.
Tip: Walk down past Kuhio Beach if you want a quieter stretch.
🌄 Hike Diamond Head Crater
This is one of Oahu’s most iconic hikes, and it’s worth every sweaty step. The climb isn’t long (under an hour), and the panoramic views of Honolulu at the top are unforgettable.
Start early to avoid the heat and crowds. Trust me—I made the mistake of starting at noon once!
🐠 Snorkel at Hanauma Bay
If you’re dreaming of colorful coral and swimming with fish, Hanauma Bay is the place. I saw parrotfish, sea urchins, and even a sleepy sea turtle in the shallows.
Reminder: Reservations are required and it’s closed on Mondays and Tuesdays.
🌺 Visit the Byodo-In Temple
Tucked into the foothills of the Koʻolau Mountains, this peaceful spot felt worlds away from Honolulu. I lit an incense stick, rang the giant bell, and soaked in the stillness.
It’s a replica of a 950-year-old Japanese temple—and it feels sacred in the best way.
🌊 Spend a Day on the North Shore
The North Shore of Oahu felt like a completely different island. Slower, quieter, more laid-back. I watched surfers tackle waves at Banzai Pipeline, then had shrimp scampi from a food truck in Kahuku.
If you’re visiting during winter, this is where you’ll find the world’s biggest waves.
🍍 Explore the Dole Plantation (and Eat the Whip)
Is it touristy? Yes. Did I love it? Also yes. I took the Pineapple Express train tour (adorably cheesy), got lost in the garden maze, and devoured a bowl of cold, creamy Dole Whip.
🏛️ Tour Pearl Harbor
It’s hard to put into words how emotional this visit was. Touring the USS Arizona Memorial felt sobering and powerful. If you’re a history lover, give yourself a full half-day here.
Book tickets online in advance—they fill up fast.
🛍️ Wander the Boutiques of Haleiwa
Haleiwa is the kind of town I could spend an entire day in. Cute surf shops, local art galleries, shave ice stands (don’t miss Matsumoto’s), and breezy cafés—this is where I slowed down.
Perfect spot to pick up souvenirs that don’t feel mass-produced.
🌿 Hike Manoa Falls
Only a short drive from Waikiki, Manoa Falls trail winds through jungle-like forest. It’s an easy walk, about 1.6 miles round-trip, ending at a tall, misty waterfall. I went early in the morning, and the trail felt magical.
Wear hiking shoes—it can get muddy!
🌅 Catch Sunset from Tantalus Lookout
One of my last nights on the island, I drove up to Tantalus Lookout. As the sun dipped behind Diamond Head and the city lights of Honolulu flickered on, I felt a lump in my throat. It was a moment that didn’t need any filters.
