I was picked up in Seminyak at 6:30 AM and arrived around 7:10 AM. We had to fill out some paperwork, and then we were told the boat would depart at 9 AM, so we had a lot of free time. There's only one unisex restroom in the Sanur Port building, and I heard there's a paid restroom if you go to the other side. I took motion sickness medication before 8:30 AM. The boat ride to Nusa Lembongan Island took about 40 minutes, and we had to disembark on the beach. You need to be careful because the waves make the boat rock a lot. We then took a truck to the restaurant. We had to wait about 30 minutes for other teams to gather, then we put our luggage in lockers and went snorkeling. On the way to the first point, we were lucky enough to see a pod of dolphins, haha. For manta rays, since they are in deep, wavy waters, it's probably best for those who are good swimmers or have snorkeling experience to go in. I went in, but only saw the blue sea and unfortunately no mantas, and the waves were so strong it was a bit scary, haha. The second point was a beach in a bay, with lots of colorful corals and fish. The waves were calm, which was perfect. The third point was right next to a cliff, and it also had many fish and calm waters. After snorkeling, they gave us towels, so we wrapped them around ourselves and headed to the restaurant. There was a hose with water gushing out, so we rinsed off the saltwater from our snorkeling gear and changed clothes in the changing room. For lunch, there was Nasi Goreng, Mie Goreng, Chicken Curry, and some vegetable dish with rice. I had Nasi Goreng and Chicken Curry. Maybe because I had just been in the water, it tasted delicious. Drinks are included, so enjoy a Coke or Sprite. After eating, we took a 15-minute boat ride to see the mangrove forest, and then another truck ride for a tour of Nusa Lembongan Island. Devil's Tear and Dream Beach were so beautiful, but the sun was really strong, so a parasol or hat is a must! For the return boat trip, we had to take off our shoes and board a small boat, then transfer to a larger boat. Perhaps the large boat couldn't come to the beach. But when I entered the sea on the beach without shoes, there were so many shells that I got a cut on my toe. The pickup was in Seminyak, but the drop-off was in Ubud. Our guide, Widi, could speak Korean, so communication was smooth, and he took many photos and was very kind, which was great! It was my first time snorkeling, and the tour itself was great value for money and very satisfying!
