Creating memorable & romantic surprises for your girlfriend or boyfriend in Thailand, specifically in Koh Phi Phi, can be an enchanting experience. Here’s a detailed plan that includes a scuba diving adventure, an underwater proposal, a romantic dinner on Long Beach, and stargazing by the shore:

Scuba Diving in Koh Phi Phi Marine National Park. A Bonding Experience:

• Begin the surprise by arranging a scuba diving experience in the Marine National Park of Koh Phi Phi. The park is home to stunning coral reefs and diverse marine life, offering a unique and immersive underwater experience. Diving together is not just a way to connect with your partner, but it offers you both the chance to discover a new world and a new activity that you can practice together on future holidays, or even weekends.

Underwater Proposal?:

• Work with a reputable local diving school to coordinate a special underwater proposal. Consider attaching a waterproof sign or using underwater communication to express your feelings while exploring the vibrant marine ecosystem together. Make sure to capture this magical moment with an underwater camera or hire a diving photographer.

Romantic Dinner on Long Beach in a Private Beachside Setup:

• After the scuba diving adventure, transition to a romantic dinner. 
• Long Beach is known for its serene atmosphere and offers a perfect setting for an intimate dining experience.
• Arrange for a private beachside dinner setup with a table for two right on the sand. Soft candlelight, fairy lights, and perhaps a bonfire can enhance the ambiance. Ensure that the dinner spot has a clear view of the iconic Phi Phi Leh in the background, creating a picturesque setting.

Catering or Local Cuisine:

• Choose a local restaurant or catering service that can provide a menu featuring authentic Thai cuisine. Enjoying a delicious meal with the sound of gentle waves and the breathtaking view of the Phi Phi Leh cliffs will add a touch of romance to the evening.

Stargazing on the Beach:

• Conclude the night by lying on the beach together and gazing at the stars. The absence of city lights on Koh Phi Phi makes it an ideal location for stargazing. Consider bringing a blanket or beach mat for comfort, and enjoy the tranquility of the night sky.

Capture the Moments:

• Whether with a hired photographer or a trusty smartphone, capture the special moments throughout the day. These photos will serve as cherished memories of your time on Koh Phi Phi.
