Hanauma Bay is a marine nature reserve and one of Oahu’s most iconic snorkeling destinations. Glide through its crystal-clear waters to encounter shimmering schools of silver fish, vibrant parrotfish, and even curious sea turtles that might swim right up to you. As a protected marine-life conservation district, the bay is a haven for biodiversity, but its popularity also poses a challenge. The delicate ecosystem faces ongoing threats from the very visitors who come to admire its beauty, making responsible tourism essential for its preservation.

The bustling Hoi An market takes a little getting used to: it's distinctly more hectic than the downtown area and teems with local vendors and shoppers as much as it does with tourists. Abundant Asian herbs, souvenirs like lacquered coconut shell bowls, Vietnamese coffee-makers and traditional cone hats are some of the wares on sale. Of particular interest are the indoor food stands serving up scrumptious snacks at some of the lowest prices in town.

One of the Hoi An Ancient Town's most emblematic structures, the Japanese Covered Bridge dates back to the early 17th century, when it was first constructed by the Japanese community as a link to the Chinese quarters of Hoi An. Much of the original ornamental wood carvings remain preserved, and so do the sculptures of two dogs and two monkeys on either end of the bridge. Although the exact reasons for this particular animal selection aren't clearly identifiable, some explanations include the sacred status of the two in Japanese culture and birth years of Japanese emperors predominantly falling on either dog or monkey. Inside the bridge, there is a tiny temple of the northern god Tran Vo Bac De, who is believed to hold powers of controlling the weather. The Japanese Covered Bridge is included on the list of attractions one can visit on an Ancient Town Entry Ticket.
