The Ultimate Guide to Diving in Indonesia: Explore the Tropical Seas with the World's Greatest Marine Biodiversity: Exploring the Tropical Seas with the World's Greatest Marine Biodiversity

Indonesia, the world's largest archipelago, is a true diver's paradise!

The tropical seas around Indonesia's 17,000 islands span several ecological zones and host the greatest variety of marine life and biodiversity found anywhere on this planet. These warm, crystal-clear waters are home to stunning coral reefs, deep trenches and shipwrecks—not to mention majestic creatures ranging from seahorses to fish, whales, dolphins, sharks and manta rays.

The Ultimate Guide to Diving in Indonesia is the first and only comprehensive guidebook dedicated entirely to Indonesia's unique and exciting dive sites and facilities. Seasoned dive instructor and long-time Bali resident Sarah Ann Wormald presents descriptions and photos for each major dive site, including recommendations for the best operators and services to use. Maps of each area, marine life and conservation stories, and detailed travel tips from a local expert help to guide you in planning your visit.

This updated and expanded third edition features many new photos, dive operators and dive sites that have surfaced over the past few years. Unique highlights include the burgeoning night-time blackwater diving scene, wall diving around Selayar Island and whale and dolphin watching off the coast of Alor.

Wormald covers each major region in Indonesia in detail, among them:

• Bali — "The Island of the Gods," famous for its marine life and the USS Liberty shipwreck off Tulamben
• North Sulawesi — Where active volcanoes tower over lush plateaus and gorgeous coral reefs
• Nusa Tenggara — The vast region from Lombok to Timor featuring everything from submerged seamounts, walls and drop-offs to freshwater caves, slopes and sandy muck diving bays
• Maluku — An often overlooked but unique sites that host the perfect combination of reefs and critters
• Raja Ampat and West Papua — Quickly becoming the "mecca" for Indonesian diving, with beautiful landscapes, white sand beaches and shallow water corals which make it the postcard trip of a lifetime
