Reach it by a local boat trip and plan around tide and weather rather than treating it like a shore entry.
Koi island is a short boat ride from the Kri area and is best treated as a shallow reef and sandbank site for snorkelers and beginner divers. The reef top is easy to scan on calm days, with coral gardens, small reef life, and a low-tide sandbank window that makes the place feel relaxed rather than technical. The outer edge can step down a little more sharply, but the main plan is slow and easy.
