I recommend that you take the following items with you when joining Fethiye Boat Tours:

1. Swimsuit/Bikini: If you want to swim in the sea on the boat tour, it is important to take a swimsuit or bikini with you. This is an essential item for sea enjoyment.

2. Sunscreen: Sunscreen is essential to protect your skin against the harmful effects of the sun. You can protect yourself from sunburn by choosing a high factor sunscreen.

3. Hat and Sunglasses: It is important to take a hat and sunglasses with you to protect your head from the sun. These items can reduce the discomfort caused by the brightness of the sun.

4. Towel: It is important to take a towel with you to dry after getting out of the sea. Although some tours provided on the tour provide towels, it is useful to bring your own towel with you.

5. Waterproof Case: You can protect your phone, camera or other electronics by putting them in a waterproof case. This will prevent your belongings from getting wet while at sea or on the boat.

6. Lightweight Clothing: Choose light and cool clothing for comfort in hot weather. Clothing such as shorts, a T-shirt or a light dress will be appropriate.

7. Sea Shoes: In some bays, the sea floor may be slippery or stony. Therefore, wearing sea shoes will allow you to walk comfortably and safely in the sea.

8. Water and Snacks: It is important to have a water bottle with you so that you do not get thirsty during the tour. Also, having a snack or a light meal will provide a comfortable experience.

These items are the basic items that you may generally need on Fethiye Boat tours. However, it's also important to contact your tour company and ask for special needs or recommendations, as each tour can be different. You may also want to consider personal preferences such as camera, cash, spare clothes, and personal medication.
