Koh Krok is a small island in Pattaya Bay and a satellite island of Koh Lan. It is located in the city of Pattaya, in the Na Kluea subdistrict, Bang Lamung district, Chonburi province. The island is about 600 meters from Koh Lan and slightly southeast of Koh Sak.

The island is known for its short, white sandy beach, only about 100 meters long, making it an ideal snorkeling spot with numerous coral reefs and sea turtles. It is a popular destination for speedboat trips or chartered boat tours, often combined with excursions to Koh Lan and Koh Sak.

Main activities on Koh Krok:

Snorkeling, fishing, and kayaking are popular activities. Since most of the island is rocky, only the small sandy beach on the east side is suitable for mooring boats and relaxing.

There are no regular public ferry services to Koh Krok.

Most tourists rely on chartered speedboats or day trips.

The journey from Laem Bali Hai Pier takes about 15-20 minutes.
