You can drive through the large garden and stop at different areas within the garden to take a walk and see unique plants. One of the best parts of this botanical garden is that it has incredible views of the mountain ridges.
5. Hike to Waimano Falls
A 3-mile round trip hike leads you to Waimano Falls. Waimano Falls is a beautiful clear blue waterfall that drops into a pool that you can swim in. The hike can be slippery so make sure to wear shoes with good traction. I hiked with these Salomon Hiking Shoes for this trail as they are light and have good traction. The trail starts on a paved road, which later turns into dirt and rocks. Follow the river upstream, and you will first see a small waterfall with a small pool. Make sure to continue up the trail to see a view of the full Waimano Falls with the bigger pool. If you choose to swim in the pool keep in mind that it does require a dangerous climb down into the pool.
6. Sunset Cruise in Waikiki
One of the best things to do on Oahu is to watch the sunset from the water. There are several different sunset cruise operators you can choose from depending on what you are looking for and how much you are willing to spend. Enjoy a relaxing evening watching the sunset from a boat with views of Diamond Head and Waikiki Beach. This BYOB sunset cruise is a great budget option.
7. Hike Kuliouou Ridge
One of the best things to do on Oahu is to hike up one of the ridges for views of the windward side. Kuliouou Ridge takes you to an incredible viewpoint with Hawaii Kai on one side and Waimanalo on the other. The trail starts from the end of a neighborhood valley with many switchbacks. You will then reach a pine forest and continue walking up to the ridge where you will have to climb countless stairs to get to the top. As you are climbing you will see views of Koko Head and Hawaii Kai harbor. The clouds often pass through so if it is cloudy when you get to the top try to wait it out a bit.
8. Relax at Lanikai Beach
Located on the windward side of Oahu, Lanikai Beach is one of the most popular beaches on the island. Lanikai Beach has views of the Mokulua Islands and very clear blue water making it the perfect scenic beach for a swim. The beach can get very crowded, so try to visit during on a weekday. Be respectful of the residents when parking in the neighborhood and be aware of the signs.
9. Explore Kualoa Ranch & Private Nature Preserve
Kualoa Ranch is a private nature preserve and a working cattle ranch. Since the 1950’s there have been over 70 Hollywood movies filmed here including Jurassic World, Jurassic Park, Jumanji, Godzilla and 50 First Dates. There are a variety of tour options to explore this beautiful area including a UTV tour, boat tour, and a Jurassic adventure tour.
10. Snorkel at Three Tables Beach
One of the best things to do on Oahu is to snorkel at Three Tables Beach on the north shore. The name comes from the three flat reef formations in the water. Make sure to bring snorkel gear so you can enjoy this top snorkeling destination. The best place to snorkel is close to the reef formations as that is where you will see the most fish and sea turtles. Be careful because the waves can push you towards the reef. You will have the chance to see a variety of colorful fish here such as the Humuhumunukunukuapua’a (Hawaii State Fish), parrot fish, cornet fish, blue tang, yellow tang, and more.
11. See Incredible Ocean Views from Makapu'u Point Lighthouse Trail
This 2.5 mile roundtrip trail on Oahu is known for views of the lighthouse, Rabbit Island, Waimanalo Beach, Olomana (three mountain peaks), and more.

On a clear day you can also see the nearby islands of Molokai, Lanai, and Maui as you are hiking up the trail. The top of the trail has three viewing platforms where you can enjoy views of Oahu and in the winter it is possible to spot whales.
12. Kaneohe Sandbar
Kaneohe Sandbar is a raised area of sand in Kaneohe Bay off the coast of Oahu that is about 1 mile wide and 3 miles long. How exposed the sandbar is depends on the tides. Usually during low tide the water is ankle deep, while at high tide it is waist deep. It is rare that the sandbar is completely exposed, but the shallow water makes it even more beautiful since it is a clear turquoise color. Kaneohe Sandbar also has reefs nearby which makes it the perfect place to snorkel. You can get to Kaneohe Sandbar by kayak or boat. Follow this guide for how to kayak to Kaneohe Sandbar.

16. Visit Secluded Beaches on the West Side
The west side of Oahu has beautiful secluded beaches that are worth checking out. Visiting these beaches on the west side is a good option if it is raining on other parts of the island as this is the dry side and it is more likely to be sunny here. First visit Makua Beach which is the second to last beach on the west side of the island. This beach has beautiful sand and is surrounded by mountains. It doesn’t usually get too busy because it is located far from other sights. Next, continue to Keawaula Beach, the final beach on the west side of the island. This scenic beach has beautiful blue water that is really nice to swim in and is also surrounded by large mountains.

Chinaman’s Hat Island, also known as Moloki’i island is a small islet off the coast of the windward side of Oahu.
