Hawaii is expensive—like “this pineapple costs how much?!” expensive. So, naturally, I was all about tracking down some fun free things to do on Oahu! Whether it was marveling at the island’s stunning scenery or finding activities that didn’t leave my wallet crying, I made it my mission to soak up as much as possible without shelling out a fortune during my summer living on Oahu.
From epic beach days to hidden gems I stumbled upon purely by accident (because I got lost), these budget-friendly finds are all about enjoying Oahu without the price tag! So pack your bags (I suggest Level8 😉) and get ready to experience the beauty of Hawaii on a budget!
Free Things to Do on Oahu
1. Cliff Jumping at Waimea Bay
Cliff jumping at Waimea Bay is one of the most exciting free activities on Oahu! Even if you skip the jump, this North Shore gem has stunning golden sands and vibrant blue waters, offering a more relaxed vibe than Waikiki’s bustling beaches.
Climbing to the top of the cliff might test your nerves, but the adrenaline rush after the leap is unforgettable! Plan to arrive early as parking fills quickly, and always check water conditions for safety.
Whether you dive in or simply soak up the views, Waimea Bay is one of the best things to do on the North Shore!
2. Watch the Sunset at Tantalus
Tantalus Lookout is my favorite spot on Oahu for catching a breathtaking sunset with minimal effort! From this scenic overlook, you get incredible views of the Waikiki skyline and Diamond Head volcano.
To make taking in the views even better, pack a blanket and some wine for a cozy picnic. The parking lot is small, so be sure to arrive early, especially before sunset. Just remember, the park closes promptly at 7:45 PM, so make sure to head out before the gate locks!
3. Watch Pro Surfers at Banzai Pipeline
If you’re not ready to try surfing yourself, the Banzai Pipeline on the North Shore offers a thrilling experience just watching the pros! Known for its massive waves, this reef break forms large, hollow curls ideal for tube riding.
The best time to visit is between November and February when the waves reach up to 30 feet. In January, the Billabong Pipeline Masters takes place here, attracting top surfers from around the world!
4. Fireworks in Waikiki
You don’t need to wait for the Fourth of July to enjoy fireworks in Hawaii! Every Friday, the Hilton Hawaiian Village Waikiki Beach Resort hosts a free, public firework show. We spent an unforgettable evening attempting to surf, watching the sunset from our boards, and then paddling in to catch the spectacular display. It’s a hard evening to beat in Waikiki!
5. Wiliwilinui Ridge Trail
If you’re looking for a hike with some serious views, the Wiliwilinui Ridge Trail should be on your list! It’s 4.7 miles of adventure, with some uphill climbs and stairs that will get your heart racing. The weather turned cloudy when we reached the top, but the views along the way were totally worth it.
Just be sure to wear solid hiking shoes (I’m obsessed with my Columbia ones!) and check the weather before you go—this trail gets super muddy after rain! Grab water, sunscreen, and bug spray, and you’re all set!
It typically takes around 3 hours to complete. To get here you’ll enter through a gated community. The guard will write down your license and give you a parking pass. Bring plenty of water, and put on sunscreen and bug spray. Check out our experience here!
6. Kuliouou Ridge Trail
Kuliouou Ridge Trail is another amazing Oahu hike! It’s a 5-mile out-and-back trail that’s a little less steep than Wiliwilinui, but you still get those breathtaking coastal views that make you want to take a million photos. It took around 3 hours to complete.
Unlike the cloudy day I got for Wiliwilinui, Kuliouou treated us to clear skies, which made the views even more epic. The hike isn’t as intense but still gives you that feeling of accomplishment with great scenery all along the way! At the top, you’ll be rewarded with epic views of Hawaii Kai, Koko Crater, Waimanalo Beach, and more.
Wear sunscreen and bug spray as some of it is through wooded areas and some of it is open.
7. Sharks Cove
Don’t worry, Sharks Cove doesn’t get its name because you’ll find sharks here. But it is one of the best spots for snorkeling in Oahu! And it has a fraction of the crowd that Hanauma Bay gets (plus there’s no admission fee!).
Known for its underwater rock formations and vibrant marine life, it’s a great place to see tropical fish and even turtles! It’s best visited in summer when the water is calm. Remember to bring reef-safe sunscreen, water shoes, and quality snorkels for the best experience!
8. Dole Plantation
Did you know the Dole Plantation is on Oahu? While you can explore the plantation for free, I recommend making a stop for the Dole Whip and chocolate-covered pineapple. Trust me, they’re worth every penny! I mean, who knew chocolate-covered pineapple was a thing?!
9. Lanikai Pillbox Hike (aka Kaiwa Ridge Trail)
The Lanikai Pillbox Hike is one of the best hikes on Oahu and offers some of the most breathtaking views! If you’re an early bird, I highly recommend tackling it at sunrise. The 1.8-mile hike is moderate, but totally worth it when you reach the top and get to climb on the military bunkers for that perfect view.
It’s a bit of a rocky path, so make sure to bring a headlamp (check out my other Hawaii packing list recommendations) if you’re starting before dawn. Parking can be tricky. Your GPS is most likely going to take you to the trail entrance right by the Mid Pacific Country Club, where there is usually a security guard letting you know you can’t park there. Finding parking along the streets has been easy enough in the early mornings!
It’s one of my favorite free things to do on Oahu and I do it every time I return to the island!

10. Byodo-In Temple
The Byodo-In Temple in Kaneohe feels like stepping into a serene slice of Japan right in Hawaii. It’s a smaller replica of the historic temple in Uji, Japan, built in 1968 to honor the first Japanese immigrants.
While not free, it’s only $5 for admission—a steal for the tranquil beauty and history you’ll experience! We spent around 45 minutes soaking in the peaceful surroundings, admiring the koi ponds, and marveling at the temple’s architecture. It’s a truly unique and affordable way to experience a cultural gem on Oahu!
11. Ho’omaluhia Botanical Garden
Once you’ve soaked in the tranquility of the Byodo-In Temple, head just 20 minutes south to the breathtaking Ho’omaluhia Botanical Garden. Nestled in a lush rainforest, this paradise is framed by majestic mountain ranges, often enhanced by a dreamy mist that ups the drama.
With trails, serene lakes, and plants from tropical regions around the globe, it’s a must-see for nature lovers. Don’t miss the collections highlighting Hawaii, Polynesia, and the tropical New World—this spot is pure botanical magic!
This is a must-see that should be at the top of your list of things to do in Kaneohe!
12. Friendship Gardens Trail
Friendship Gardens Trail is a peaceful, kid-friendly loop trail that’s just 0.5 miles long—perfect for a quick nature walk. Be careful, though, as it connects to a larger loop marked by pink ribbons, which we accidentally followed and ended up hiking much more!
This lush, shaded trail is lightly trafficked and features a stunning lookout spot. Bug spray is a must, and be prepared for mud if it’s rained. Parking is limited (3-4 spots right by the trailhead), but you can park at the bottom of the hill and walk up if needed.
13. Crouching Lion
The Crouching Lion hike, about 25 minutes outside of Kaneohe, earns a strong runner-up for one of the best hikes in Oahu! Though only 0.4 miles, this out-and-back trail packs a punch with its steep climb and jaw-dropping views.
Avoid hiking after rain—it gets dangerously slippery. The warning signs at the entrance aren’t just for show, as there are sheer drops near the summit.
The hike took us a little over an hour, including time spent soaking in the stunning panoramas. Parking was easy on the roadside during our weekday afternoon visit!
14. Diamond Head
Lē‘ahi, better known as Diamond Head, isn’t just iconic—it’s the superstar of Hawaii hikes! This 0.8-mile trail is short, sweet, and oh-so-rewarding, with jaw-dropping views of Waikiki waiting for you at the top.
The hike is moderate, so it’s perfect for most adventurers, and you can conquer it in under an hour (bonus points for working up a sweat!). Along the way, you’ll get a little history and geology lesson. Plus, no tour is needed, so it’s a budget-friendly way to soak up some of Oahu’s best scenery!
15. Hit the Beach
No trip to Hawaii is complete without some beach time, and with over 112 miles of stunning coastline, this island offers a wide variety of awesome beaches to choose from! Here are some of my favorites:
- Lanikai Beach: Perfect for dreamy sunsets and exploring charming Kailua town nearby.
- Laniakea (Turtle) Beach: The best place to spot Hawaiian green sea turtles—just keep an eye out from the road!
- Waikiki Beach: Iconic for its surf-friendly waves, Diamond Head views, and downtown vibes.
- Electric Beach: A snorkeling haven where you might spot spinner dolphins—It’s one of the best things to do in West Oahu.!
16. Cockroach Cove
Ready for a secret slice of paradise? Cockroach Cove is one of Oahu’s hidden gems, tucked between Hanauma Bay and the Halona Blowhole. The beach is a serene haven, perfect for swimming and soaking up views of the blowhole in action.
To get there, you’ll have to navigate a narrow staircase (but trust me, it’s worth it!). Once you’re there, the photos and the peaceful vibes will make the extra steps totally worth it.
17. Pearl Harbor
Pearl Harbor is a historical site honoring the 1941 attack that led the U.S. into World War II. It’s one of Hawaii’s top attractions, with over a million visitors each year. The USS Arizona Memorial, where many lives were lost, is the main draw for visitors, though there are several other points of interest on the site.
It’s a poignant, educational experience, offering a glimpse into the events that changed the course of history.
