Waioli offers breakfast, lunch, and a variety of pastries. The building has a large patio for outdoor seating, or you can opt to sit indoors and enjoy the historic tea room. They do add a 3% "training fee" to orders (which they will remove upon request). The fee basically offsets their expenses to train staff, which seems like a ordinary business overhead cost, but why not pawn it off on unsuspecting tourists?! Weird fees, but good food.

Manoa Falls is one of the most spectacular waterfalls on Oahu to see! The fall is 150 feet tall and cascades down into a lush jungle. You can swim in the pool formed at the bottom to cool off! If you enjoy climbing and seeing the less-traveled roads, Lā-'ī Road and Waiomao Road can help you sneak in that little bit extra!

Tantalus Lookout allows you to see all the way to Diamond Head in the east, and to Honolulu International Airport and Pearl Harbor in the west. This spot is particularly popular at sunset due to the west facing view. Once you get to the upper parking lot, you will have to push your bike a very short distance to get to the end of the lookout area.

Thomas Square is Hawaii's oldest city park. It is one of four sites in Hawaii where the Hawaiian flag is allowed to fly alone without the United States flag. Just north of the square is a gas station and a Mako's to restock on any food/drinks.

The Manoa Cliff Trailhead is located just a few yards away from the parking lot at Round Top Drive. Make sure to clean your shoes before entering the trail to prevent the spread of Rapid ʻŌhiʻa Death, a fungal disease.

Tantalus Lookout offers one of the nicest views on the whole island. While relaxing on a comfortable lawn, you can watch the sunset over Honolulu and Diamond Head. A spectacular view, that you won't forget that quickly.
