Telo Islands, also known as the Batu Islands are situated almost directly atop the equator and are often calm and pleasant throughout the year. There are many white sand beaches and karst cliff formations and the area is often compared to a smaller version of Thailand or Raja Ampat.
The water clarity suffers a bit and sometimes takes on a green huge while at other times it is clear for snorkeling and diving. Surfing is almost always spectacular and of a more gentle nature than the raw ocean swell found in the Mentawais.
