1. Enjoy a private candlelit dinner at Anantara Bophut Koh Samui



For couples celebrating a honeymoon, anniversary or proposal, Designer Dining at Anantara Bophut Koh Samui Resort transforms an ordinary dinner into a private experience created around the occasion.


Set directly along Bophut Beach, the resort offers two distinctive private dining locations. Couples can choose a candlelit table on the sand, framed by flowing white drapes, or an intimate sala overlooking the tranquil lotus pond. Both settings feature personalised table decorations, floral arrangements and music tailored to the occasion.


The experience centres on a carefully prepared multi-course menu. Options include Mediterranean-inspired dishes, Thai flavours and seafood, with examples such as Phuket lobster, aged beef tenderloin and rich chocolate desserts appearing on the published menu. Couples choose a shared menu selection, creating a coordinated dining experience.


What makes Designer Dining particularly appealing is the privacy. Rather than sharing a busy restaurant with other diners, couples can enjoy an evening dedicated to conversation, food and the atmosphere around them.


2. Enjoy a Couples' Spa Experience at Jai Spa, Mantra Samui Resort



Not every romantic experience needs an elaborate itinerary. Sometimes, the most enjoyable thing couples can do together is set aside a few hours to relax. Situated within the adults-only Mantra Samui Resort, Jai Spa offers a peaceful setting for couples seeking a break from sightseeing, busy schedules and everyday routines.


The spa provides traditional Thai massage, aromatherapy oil massage, foot reflexology, facials and body treatments. Natural ingredients and therapies delivered by experienced Thai therapists create an experience centred on physical relaxation and personal comfort.


Couples can choose treatments according to their preferences. A traditional Thai massage combines pressure and stretching techniques, while an aromatherapy oil massage offers a different experience using flowing massage movements and aromatic oils.

After a treatment, couples staying at the resort can continue their afternoon beside the infinity pool or enjoy a relaxed meal at The View Kitchen + Bar. The combination of spa treatments, ocean views and unhurried dining creates an appealing way to spend a romantic afternoon.


For couples celebrating an anniversary, a spa experience can be a welcome alternative to a full day of sightseeing. It also works particularly well after a boat excursion or an active morning exploring the island.


3. Explore Ang Thong National Marine Park on a romantic day trip


  • Departure Point: Boat tours depart from various Koh Samui piers, including Nathon Pier and Petcherat Pier in Bangrak, depending on the operator.

  • Vibe: Adventure & nature

  • Time needed: Around 1 day

  • Park opening hours: 08:00–17:00 during the operating season

  • Entrance fee: THB 300 per foreign adult; THB 150 per foreign child aged 3–14

  • Tour price: Boutique Yachting's full-day cruise aboard S/Y Naga costs THB 4,900 per person, including national park admission.


For adventurous couples, Ang Thong National Marine Park offers one of the most spectacular natural landscapes near Koh Samui. Located approximately 30 kilometres offshore, the protected archipelago consists of 42 islands surrounded by limestone cliffs, secluded beaches and emerald-coloured water.


A full-day boat excursion allows couples to explore the park together, from kayaking through sheltered bays to discovering Thale Nai (Emerald Lake) on Koh Mae Ko. One of the most memorable experiences is hiking to the viewpoint on Koh Wua Ta Lap, where sweeping panoramas of the surrounding islands provide a beautiful backdrop for photographs.

For couples seeking a more comfortable journey, Boutique Yachting's Ang Thong Discovery Day Cruise aboard S/Y Naga offers a sailing experience with scenic island views and opportunities to enjoy the marine park's natural surroundings. Its THB 4,900 package includes the national park entrance fee, making it easier to plan the overall excursion budget.


Ang Thong National Marine Park is generally closed from 1 November to 15 December due to seasonal monsoon conditions. Couples planning an island adventure should consider this when choosing their travel dates.


4. Take a private longtail boat to Koh Madsum (Pig Island)


  • Departure Point: Thong Krut Pier, southern Koh Samui, Surat Thani, Thailand

  • Vibe: Playful, tropical & adventurous

  • Time needed: Around 4–6 hours, including transfers

  • Best visiting hours: 08:00–10:00 for a quieter island experience

  • Island entrance fee: THB 50 per person, payable in cash upon arrival

  • Private boat price: Standard local longtail boats around THB 2,000–2,500 per boat; premium private longtail charters from THB 4,395 for 1–5 guests, excluding hotel transfers and meals


For couples who enjoy discovering somewhere a little different, a private boat trip to Koh Madsum, commonly known as Pig Island, offers a playful and memorable half-day adventure. Located off Koh Samui's southern coast, the island is famous for its friendly pigs roaming freely along white-sand beaches, creating an unusual tropical experience and plenty of opportunities for photographs together.


The journey begins at Thong Krut Pier, a small fishing village on Koh Samui's southern coastline. From here, a traditional longtail boat takes approximately 20–25 minutes to reach Koh Madsum. Most excursions also include a stop at nearby Koh Tan, where couples can snorkel in clear waters and discover tropical marine life before continuing to Pig Island.


Once on Koh Madsum, couples can stroll along the shoreline, watch the pigs exploring the beach or enjoy a refreshing drink beneath the palm trees. Arriving between 08:00 and 10:00 offers a more peaceful experience before larger tour groups begin arriving later in the morning.


For couples seeking privacy and flexibility, a private longtail boat is an excellent choice. Standard local boats offer a more affordable way to explore the islands, while premium charters feature decorative seating, comfortable cushions and photography-friendly arrangements. Premium private boats start from THB 4,395 for up to five guests, with hotel transfers, meals and island admission charged separately.


Beyond meeting the island's famous residents, the experience is about enjoying the journey together, from snorkelling around Koh Tan to relaxing on Koh Madsum's tropical beaches.


5. Share a peaceful beach morning at Silver Beach (Crystal Bay)


  • Address: Silver Beach, 205 Moo 4, Maret, Koh Samui 84310, Thailand

  • Vibe: Peaceful beach escape & slow romance

  • Time needed: Around 2–4 hours

  • Best visiting hours: Before 10:00 or after 15:00

  • Entrance fee: Free public beach access

  • Additional costs: Basic beach chairs around THB 100 each; Crystal Bay Beach Club loungers THB 500 per day with a towel; snorkelling equipment around THB 200 per half-day; kayak rental around THB 300–500 per hour.


Silver Beach, also known as Crystal Bay, is a sheltered 250-metre cove between Chaweng and Lamai on Koh Samui's eastern coastline. Framed by tropical greenery and large granite boulders, its soft white sand and clear turquoise water create an intimate setting for couples seeking a quieter beach experience.


Start your morning with a leisurely walk along the shoreline before swimming together in the bay's sheltered waters. The sandy central section is particularly inviting for a refreshing dip, while the rocky edges offer opportunities to spot tropical fish while snorkelling. Water shoes are useful when exploring these areas, especially where submerged rocks are exposed at low tide.

For a more active date, couples can rent a double kayak and paddle along the coastline, discovering a different perspective of the surrounding granite formations. Alternatively, settle into a sun lounger at Crystal Bay Beach Club, where you can enjoy refreshments, Thai cuisine and beachfront relaxation.


The beach is free to access, with optional facilities to suit different budgets. Basic beach chairs are available from around THB 100, while Crystal Bay Beach Club offers loungers with towels for THB 500 per day.


Because Silver Beach is relatively small, it becomes livelier as day visitors arrive. Visiting before 10:00 offers a more peaceful atmosphere, with time for swimming, photographs and a relaxed beachfront breakfast or lunch.


6. Sail into the sunset with Boutique Yachting Koh Samui



Watching the sunset from the water offers a different perspective of Koh Samui, particularly for couples looking for a special experience to mark an anniversary or romantic getaway.


Boutique Yachting Koh Samui offers sunset sailing experiences aboard the Naga, a traditional-style wooden yacht designed for leisurely cruising around the island.


The advertised sunset itinerary departs from Petcherat Pier in Bangrak and follows Koh Samui's northern coastline. As the boat moves through the bays, couples can relax on the open deck, enjoy refreshments and watch the changing colours of the evening sky.


The slower pace is one of the experience's main attractions. Instead of travelling quickly between sightseeing stops, guests can enjoy the journey itself, with time to take photographs, appreciate the coastal scenery or simply sit together watching the horizon.


The scheduled sunset cruise includes hotel transfers, a welcome drink, finger food, soft drinks, water, towels, insurance and an English- or German-speaking guide. For couples planning a more exclusive celebration, Boutique Yachting also offers private sunset charters. These allow greater flexibility over the itinerary and onboard arrangements, with additional food and beverage options available by request.


Private charters are particularly suitable for proposals, anniversaries and other special occasions where couples want to create a more personalised experience.


The operator's published sunset itinerary runs from 17:00 to 20:00, although scheduled departures depend on availability. Private charter requests can be made directly through the operator.


7. Reconnect as a couple through a wellness experience at SAOL



Not every romantic experience in Koh Samui has to involve a candlelit dinner or a sunset cruise. Sometimes, the most meaningful moments come from slowing down, trying something new together and enjoying time away from everyday routines.


Set within the peaceful hillside surroundings of Mantra Samui Resort, SAOL Wellness Retreat offers couples an opportunity to reconnect through shared wellbeing experiences inspired by the Simple Art of Living philosophy.


Couples can choose from wellness activities that combine movement, relaxation and time in nature. For those looking for something more immersive, the SAOL Connection programme is particularly suited to couples, bringing together Muay Thai fitness, water boxing and curated nature and cultural experiences that encourage meaningful connections.

After a day of activities, couples staying at the resort can unwind beside its infinity pool overlooking the Gulf of Thailand, where the peaceful hillside setting offers a beautiful backdrop for spending unhurried time together.


Whether enjoying a mindful activity or embarking on a longer wellbeing journey, SAOL offers a refreshing alternative to conventional romantic experiences, allowing couples to create shared memories while caring for their wellbeing.


8. How to plan a romantic day in Koh Samui


For a leisurely day, begin with a swim at Silver Beach or enjoy breakfast overlooking the coast. In the afternoon, unwind with a couples' spa treatment at Jai Spa before heading to Taling Ngam for a sunset dinner.


Couples who prefer adventure can dedicate an entire day to Ang Thong National Marine Park, combining kayaking, viewpoints and island scenery. A half-day trip to Koh Madsum offers a shorter alternative, leaving the afternoon free for relaxation.


It is also worth considering the location of each experience. Anantara Bophut and Mantra Samui Resort are in the northern part of Koh Samui, while Taling Ngam and the departure point for Koh Madsum are farther south. Silver Beach lies on the eastern coastline, between Chaweng and Lamai.
