Beaches Bai Dai & Bai Thom
These are both remote beaches: Bai Dai is in the far northwest and Bai Thom is on the northeastern coast. A new road to Bai Dai cuts down on motorbike time and red dust in your face. You can rest assured that neither beach will be crowded.
Both are in military areas, but Bai Dai is open to the public and has a couple of restaurants, The military usually opens Bai Thom to civilians on Sunday but you must leave your passport with the military receptionist while you're on the base. In any event, do not try to sneak onto the beaches: make local inquiries and obey the rules.
Bai Cua Can & Long Beach
The most accessible beach, Bai Cua Can is in the northwest. It's 11km from Duong Dong.
Long Beach (Bai Truong) is indeed a long, spectacular stretch of sand from Duong Dong southward along the west coast, almost to An Thoi port (20km). The southern end of the beach is known as Tau Ru Bay (Khoe Tau Ru). The water is crystal clear and the beach is lined with coconut palms.
Long Beach is easily accessible on foot (just walk south from Duong Dong's Cau Castle), but you will need a motorbike or bicycle to reach some of the remote stretches towards the southern end of the island. The beach around the family-run guesthouse area is a particularly popular spot. There are a few bamboo huts where you can buy drinks, but bring water if you're planning a long hike along this beach.
Bai Sao & Bai Dam
Two beautiful white-sand beaches along the southeastern part of the island are Bai Sao and Bai Dam, situated just a few kilometres from An Thoi. There are a couple of beachfront restaurants at Bai Sao.
Just south of these beaches is undeveloped Bai Khem, one of the most beautiful beaches on the island and also, sadly, a military area that's closed to the public.
SUOI DA BAN
Compared with the waterlogged Mekong Delta, Phu Quoc has very little surface moisture; however, several springs originate in the hills. The most accessible of these is Suoi Da Ban (Stony Surface Spring). Basically, it's a white-water creek tumbling across some attractive large granite boulders. There are deep pools and it's pleasant enough for a swim.
FOREST RESERVE
Phu Quoc's poor soil and lack of surface water have disappointed farmers for generations, although their grief has been the island's environmental salvation. About 90% of the island is forested and the trees now enjoy official protection. Indeed, this is the last large stand of forest in the south. The forest is most dense in the northern half of the island. The area is a forest reserve (Khu Rung Nguyen Sinh). You'll need a motorbike or mountain bike to get into the reserve. There are a few primitive dirt roads, but no real hiking trails.
AN THOI ISLANDS
Off the southern tip of Phu Quoc are the tiny An Thoi Islands (Quan Dao An Thoi). These 15 islands and islets can be visited by chartered boat, and it's a fine area for sightseeing, fishing, swimming and snorkel-ling. Hon Thom (Pineapple Island) is about 3km in length and is the largest island in the group. Other islands here include Hon Dua (Coconut Island), Hon Roi (Lamp Island), Hon Vang (Echo Island), Hon May Rut (Cold Cloud Island), Hon Dam (Shadow Island), Chan Qui (Yellow Tortoise) and Hon Mong Tay (Short Gun Island). Most boats depart from An Thoi on Phu Quoc, but you can make arrangements through hotels in Duong Dong. The Tropicana Resort has a large boat for charter that can make the trip directly from Long Beach. . Boat charters are seasonal and generally do not run during the rainy season
DIVING & SNORKELLING & KAYAKING
Though Nha Trang gets the biggest billing as Vietnam's best dive destination, diving opportunities also abound around Phu Quoc - but only during the dry months of November to May. The reputable Rainbow Divers has a dive centre on the island and offers a wide range of diving and snorkelling trips. Find it at Saigon-Phu Quoc Resort.
Other dive outfits are Coco Dive Center ( 58 Tran Hung Dao Str ) and Vietnam Explorer ( 36 Tran Hung Dao Str).
There are several places to rent kayaks along Bai Sao beach, and its protected, fairly calm waters make for a smooth ride. In addition to locals who hire out boats, you can ask at either restaurant along the beach.
