Visitors to Phu Quoc find a Vietnamese island paradise, so it's all too easy to lounge on the beaches but forget about exploring the lovely islands peppering the Gulf of Thailand. On this full-day cable car and speedboat excursion, you can see the highlights in just few hours with a trip to four different islands. On your adventure, try snorkeling, swimming, and fishing, ride the longest cable car system in the world, and enjoy lunch—all included.
