let’s explore Koh Khai Nai, affectionately called “Cat Island”! This tiny island is part of the Khai Islands near Phuket in southern Thailand. Despite being only about 50 meters long, it offers soft white sand, crystal-clear shallow waters, and over 80 friendly cats roaming freely.

We can spend the day swimming, snorkeling, or just relaxing on the beach while watching the cats explore the sand. The island’s compact size means everything is within a short walk, making it perfect for a quick getaway or a day trip from Phuket.

Best Time to Visit

The ideal months are November to April, Thailand’s dry season, when the weather is sunny and the sea calm. To avoid crowds, it’s best to visit early morning (8–10 AM) or late afternoon (3–5 PM). Morning waters are calmest for snorkeling, while late afternoon offers soft sunlight perfect for photos.

Things to Do on the Island

Koh Khai Nai offers a mix of relaxation and adventure:

- Relaxing on the Beach: Sunbeds and umbrellas can be rented for $4–$6 per day. We can simply lay back, enjoy the soft sand, and watch the cats wander around.

- Snorkeling: The shallow, calm waters make it perfect for beginners. Snorkeling gear rental is around $3–$5. Although there aren’t as many colorful fish as on other islands, it’s a safe and scenic spot.

- Water Sports: For a more active day, jet skis, banana boats, and kayaks are available from $12 per 30 minutes.

Remember, feeding the fish is illegal across the Khai Islands, so we should enjoy the wildlife without disturbing it.

Family-Friendly Fun

Families will love Koh Khai Nai! Children can safely play in the warm, shallow waters. The beach is a gentle introduction to snorkeling, helping kids learn to float and observe marine life.

Ice cream stands are scattered along the beach, with prices around $1.50–$2.50 per scoop. Small restaurants also offer Western-friendly meals, typically $4–$9, making it easy to feed hungry little adventurers.

Meeting the Cats

Over 80 cats live on the island, freely roaming and often hanging around restaurants for scraps. We can pet and observe them, but feeding is not recommended since their vaccination status is uncertain. The cats are playful and make for a unique island experience that’s both fun and relaxing.

Dining Options

The island has a few simple restaurants and bars:

- Restaurants: Thai meals $4–$9 per person.

- Cold Drinks: Soft drinks or coconut water $1.50–$3.

If we’re on a tight schedule, it’s wise to tell restaurant staff before ordering so our meals come quickly.

Restrooms and Facilities

Toilet facilities follow the typical Thai style. A small fee of $0.60 is required, so it’s handy to have some cash on hand.
