10 Days Gulf Islands: Koh Samui, Koh Phangan & Koh Tao

Fly into Koh Samui airport and grab a taxi or songthaew to your hotel in Chaweng or Lamai — the ride takes about 15-20 minutes depending on your base. Check in, drop your bags, and head straight for the beach to shake off that travel fatigue. Book accommodation in advance during peak season as the best beachfront spots fill up quickly. Chaweng is the main beach with its long stretch of white sand, buzzing with restaurants, bars, and water sports operators calling out jet ski rentals. The water here gets choppy with boat traffic, but the energy is infectious. Lamai offers a more laid-back vibe with better swimming conditions — the bay is more protected, so the water stays calmer and clearer. Both beaches have plenty of loungers and umbrella rentals for about 100-200 baht per day. Spend your afternoon getting familiar with the island's rhythm. If you're staying in Chaweng, walk the main strip to scope out restaurants for later. Lamai folks should check out the quirky Grandfather and Grandmother rocks (Hin Ta Hin Yai) just a short walk south. Bring reef-safe sunscreen — the tropical sun here is no joke, even on cloudy days. As evening approaches, make your way to Lad Koh Viewpoint for sunset over the neighboring islands. The drive up takes about 15 minutes from either beach, and you'll want to arrive by 6 PM to snag a good spot. For dinner, try som tam (papaya salad) and grilled seafood at one of the beachfront restaurants. Chaweng has more nightlife options, while Lamai keeps things mellow with beachside dining.

Catch the 8:30 AM speedboat from Nathon Pier for the full-day trip to Ang Thong National Marine Park's 42 limestone islands. Book your tour the day before to secure a spot, as this popular excursion fills up quickly during peak season. The 45-minute journey offers glimpses of towering karst formations rising from turquoise waters. Your first stop is typically Mae Koh Island for the famous Emerald Lake viewpoint. The 20-minute uphill hike rewards you with panoramic views of the jade-colored saltwater lake surrounded by dramatic cliffs. Most tours then move to kayaking through secret lagoons where you'll paddle between towering rock walls and spot monitor lizards sunning on the rocks. Pack reef-safe sunscreen and water shoes for the rocky beach entries, as the limestone can be sharp underfoot. Afternoon brings snorkeling at Wao Island's coral gardens, where parrotfish and angelfish dart between brain corals and sea fans. The water stays shallow here, ideal for beginners who want to float and observe the reef life below. The enclosed waters stay remarkably calm, making this perfect even if you've never kayaked before. Swimming at Talay Nai beach caps off the day before the return journey around 4 PM. Back in Koh Samui by evening, head to Fisherman's Village in Bophut for dinner. Try the grilled prawns with garlic at Coco Tam's or the massaman curry at Happy Elephant. The beachfront restaurants here offer the perfect spot to watch the sunset while your sun-soaked skin cools down.

Start early at Big Buddha temple around 8am to beat the crowds and heat. The 12-meter golden statue sits atop a small hill with panoramic views over the northeast coast. From there, drive 15 minutes to Wat Khunaram to see the mummified monk Loung Pordaeng, preserved in a meditation pose since 1973. Rent a scooter or hire a taxi for the temple circuit — public transport is limited between these sites. The famous Grandfather and Grandmother Rocks (Hin Ta and Hin Yai) make for an interesting midday stop, where naturally formed stones have become fertility symbols for locals. The rocks sit right on Lamai Beach, so you'll hear waves crashing while vendors sell coconuts and snacks nearby. The formations really do look like what locals claim they resemble, and the surrounding beach offers a nice break from temple hopping. The afternoon calls for serious pampering at one of Samui's luxury spas. Book treatments at places like Kamalaya or The Spa at Four Seasons, where traditional Thai massage meets modern wellness in oceanfront pavilions with skilled therapists trained in ancient healing techniques. Wear comfortable clothes you can easily change out of, and arrive 30 minutes early to enjoy the relaxation areas. Evening plans depend on the day — if it's Friday, head to Fisherman's Village Walking Street in Bophut for handmade crafts and street performances. Other nights, explore Chaweng's night market for som tam (papaya salad) or grilled seafood from the stalls, then grab drinks at beachfront bars. Prices at night markets are negotiable, so don't accept the first offer.

Catch the morning ferry to Koh Phangan — the 30-minute ride from Koh Samui gives you time to plan your island exploration. Head straight to the scooter rental shops near Thong Sala pier; getting wheels early means beating the crowds to the best spots. Most rental shops open by 8am, and grabbing a bike before 9am guarantees better selection and prices starting around 200 baht per day. By midday, you'll be cruising toward the north coast where Haad Salad awaits with its crescent of white sand and swaying palms. The water here shifts from turquoise to deep blue as you wade out, and the beach stays blissfully uncrowded. Bottle Beach, accessible via a bumpy dirt track, offers even more seclusion — just you, the waves, and maybe a handful of other travelers who made the journey. Spend your afternoon beach-hopping or exploring inland trails that wind through jungle and rubber plantations. Keep your tank topped up and bring plenty of water — some remote beaches don't have facilities. The roads can be steep and winding, so take it slow if you're new to scooter riding. Wear closed shoes for better grip, and always keep your helmet on even for short rides. Evening calls for either Thong Sala night market, where som tam and grilled fish hit the spot, or a beachfront bar in Srithanu watching the sunset over a Chang beer. The night market fires up around 6pm with the best papaya salad stalls clustering near the main entrance. Try the khao kriab pak moh — sticky rice dumplings that locals queue up for at the third stall from the corner.

Start your morning early with a yoga class at one of Srithanu's beachfront studios around 8am. The beach town has become Koh Phangan's wellness hub, with several excellent options along the main strip. Most classes cost 400-500 baht and you can walk or rent a scooter to get there from anywhere on the island. Book ahead during high season as popular instructors fill up quickly. Head to Phaeng Waterfall next, the island's biggest cascade tucked into the jungle interior. The 20-minute hike through dense forest leads to a multi-tiered falls where you can swim in the natural pools. The water stays refreshingly cool even on hot days, and the mist creates perfect relief from humidity. The sound of rushing water drowns out everything else, making it feel completely isolated from the world outside. Spend your afternoon at one of the quieter beaches away from the crowds. Bottle Beach or Thong Nai Pan Noi offer white sand and clear water without the party scene. Bring snorkeling gear if you have it, as the coral near the rocks is worth exploring. Pack water and snacks since beachside restaurants can be pricey at these remote spots, and wear reef-safe sunscreen to protect the marine life. For dinner, try som tam and grilled fish at the local spots in Srithanu village. The night market near Wat Pho temple serves excellent pad kra pao and mango sticky rice at half the price of tourist areas. If tonight happens to be Full Moon night, fuel up well because the party at Haad Rin kicks off after 10pm and runs until sunrise.

A day with no plan. Start your morning around 8am with fresh fruit and coffee at your hotel before the heat builds up too much. Most songthaews to Thong Nai Pan Noi cost 150 baht from the main towns, so grab one by 9:30am to beat the crowds and secure the best kayak spots. By 10am, head to Thong Nai Pan Noi Beach on the island's northeast coast for kayaking. The protected bay offers calm waters perfect for paddling, with limestone cliffs rising from emerald shallows. Rent kayaks directly from beachside operators for about 200 baht per hour. The gentle splash of your paddle and distant bird calls from the jungle create a meditative rhythm that washes away any lingering stress. After working up an appetite on the water, treat yourself to a traditional Thai massage right on the sand. Beach massage ladies charge around 300-400 baht for an hour of skilled hands working out every knot. Bring a sarong to cover up afterward and stay hydrated - the combination of sun and massage can be more tiring than expected. The afternoon shade under beach umbrellas makes this the perfect time for reading in a hammock or trying stand-up paddleboard. Evening calls for som tam and grilled fish at one of the beachfront restaurants. Try the pla pao (salt-crusted whole fish) with sticky rice while your feet sink into cool sand. Most places here close early, so aim for dinner by 7pm to avoid disappointment.

Catch the morning ferry north to Koh Tao — departing around 9:30am gets you there by 11:30am without the afternoon rush. This tiny island punches way above its weight, where more people get scuba certified than anywhere else on earth. The ferry docks at Mae Haad pier, and songthaews wait right there to whisk you to your accommodation. Book your ride before boarding since drivers sometimes hike prices for walk-ups. Head straight to Sairee Beach, the main strip where most of the action happens. The white sand stretches for nearly two kilometers, backed by dive shops, restaurants, and that classic Thai beach energy. You'll hear a dozen languages as instructors prep their students for afternoon dives. The water here stays calm most of the year, perfect for a quick swim before lunch. Grab a spot under the casuarina trees — they provide better shade than umbrellas and won't cost you 100 baht. Spend your afternoon snorkeling at the southern beaches, particularly around Chalok Baan Kao or Freedom Beach. The coral sits close to shore, so you don't need a boat trip to see parrotfish and angelfish cruising the reefs. Bring reef-safe sunscreen — many shops here sell it, but it's pricier than Bangkok. The rocky headlands between beaches offer decent snorkeling spots if you're comfortable swimming in deeper water. For dinner, try Barracuda on Sairee Beach for their massaman curry with tender beef, or head to Pranee's Kitchen for authentic som tam that'll clear your sinuses. The beachfront bars fire up around sunset — Fizz Bar does excellent mojitos while Maya Beach Club draws the party crowd after 10pm.

Start early at 7:30am when dive shops open and visibility is at its best. Most operators pick up directly from your hotel, so book your spot the evening before as popular sites fill up quickly. Certified divers can head to Chumphon Pinnacle for whale shark encounters during season (March-May), while Sail Rock offers the Gulf's most impressive underwater landscapes with its chimney swim-through. The underwater world here delivers serious wow factor — imagine floating above Sail Rock's vertical walls where barracuda spiral in silver tornadoes, or watching blacktip reef sharks cruise the shallows at Shark Bay. Snorkelers shouldn't feel left out; Japanese Gardens lives up to its name with colorful hard corals resembling a manicured underwater garden. Water temperature stays around 28°C year-round, making for comfortable extended sessions. Afternoon dives target Southwest Pinnacle, known for larger pelagic species and excellent macro photography opportunities. Between dives, boats typically stop at Hin Wong Bay where you can snorkel directly from the beach. Pack reef-safe sunscreen and a rashguard — the tropical sun reflects intensely off the water, and you'll burn faster than you realize. After a day underwater, grab dinner at Barracuda Restaurant on Sairee Beach for their famous red curry with prawns, or try New Heaven for wood-fired pizzas with a view. Most dive shops offer evening Nitrox courses if you're planning more diving tomorrow.

Start early with the hike to John Suwan Viewpoint — the classic Koh Tao postcard shot that everyone's after. Head out around 7am when it's still cool and the light is perfect for photos. The trail starts behind the health center near Mae Haad pier, and it's about a 20-minute climb through jungle paths. Wear proper shoes since some sections get slippery, especially after morning dew. Once you've captured that iconic shot of Koh Nang Yuan connected by its narrow sandbar, rent a kayak from Mae Haad to paddle over to Freedom Beach. This tiny slice of sand is only accessible by water, making it refreshingly quiet compared to the main beaches. The turquoise water here is perfect for snorkeling, and you'll likely spot parrotfish and angelfish around the coral patches just offshore. The paddle takes about 15 minutes, so bring a dry bag for your valuables. Spend your afternoon at Tanote Bay for some cliff jumping action. The rocks on the right side of the bay offer jumps from 3-8 meters high — start small and work your way up. The locals will show you the safe spots to leap from. Pack water shoes since the rocky entry can be tough on bare feet, and bring a waterproof bag for your phone. End your Koh Tao adventure watching the sunset from the rooftop bars along Sairee Beach. AC Bar has the best elevated views, while Fizz Beach Lounge serves excellent pad kra pao gai. Try their fresh barracuda if it's on the menu — the fishing boats come in daily with the catch.

Wake up early for that final morning swim before the island gets busy. The water at Sairee Beach is calmest around 7-8am, perfect for a peaceful last dip. Pack your bags and check out, but most accommodations will store luggage while you enjoy your final hours on the island. Around midday, the salty breeze carries the sound of longtail boats puttering across the bay as you soak up those last rays. The white sand between your toes and the gentle lapping of turquoise water against the shore create the perfect send-off from this diving haven. Grab a final coconut shake from one of the beachfront bars – they're cheaper here than at the ferry pier. Head to Mae Haad Pier by 1pm for afternoon departures, giving yourself plenty of buffer time. The ferry back to Koh Samui airport takes about 2 hours via Koh Phangan, or you can catch the 1.5-hour direct ferry to Chumphon for the overnight bus combo to Bangkok. Book your onward transport in advance during peak season to avoid disappointment. If catching an evening flight from Samui, the airport's small but decent – try the tom kha gai at the departure lounge restaurant. For the overnight journey to Bangkok, stock up on snacks and water at Chumphon pier, as options on the bus are limited and overpriced. The AC on these buses runs cold, so pack a light jacket even though you're leaving tropical weather behind.
