Island adventures beyond Bali

Indonesia, the world’s largest archipelago with over 17,000 islands, is globally known for Bali’s beaches and Java’s temples. But in 2025, savvy travelers are skipping the usual routes and heading to hidden gems—less crowded, equally breathtaking islands that still retain their untouched magic. From secret diving havens to quiet cultural escapes, here are the top ten lesser-known Indonesian islands worth adding to your travel list.

1. Belitung Island – Bangka Belitung Province

Granite boulders and calm seas
Belitung, located off the east coast of Sumatra, is famous for its white-sand beaches dotted with giant granite rocks—reminiscent of the Seychelles. Tanjung Tinggi and Tanjung Kelayang beaches offer calm waters perfect for kayaking and snorkeling. The island has also become more accessible, with direct flights from Jakarta.

2. Karimunjawa Islands – Central Java

Snorkeler’s paradise
This cluster of 27 islands north of Semarang is a marine national park and remains a favorite for snorkelers and divers. Expect crystal-clear waters, vibrant coral reefs, and traditional Javanese fishing villages. It’s ideal for backpackers seeking a chill, island-hopping vibe without the Bali crowds.

3. Wakatobi – Southeast Sulawesi

World-class diving, minus the crowds
Wakatobi is often called one of the world’s best dive destinations. Its rich marine biodiversity and protected coral reefs attract serious divers from around the globe. But what makes it special is its remoteness—far from overdevelopment, the experience feels personal and pristine.

4. Weh Island – Aceh

Off-the-grid escape
Located at the very northern tip of Sumatra, Weh Island is perfect for those who want to go completely off the grid. Known for its relaxed pace and inexpensive diving spots, the island also offers hot springs, volcanic landscapes, and untouched jungle trails.

5. Morotai – North Maluku

WWII history meets clear waters
Morotai played a role in World War II and still has remnants of its past, including plane wrecks and war relics. Today, it’s emerging as a low-key adventure destination with uncrowded beaches, warm waters, and local homestays. It’s best for travelers who love history and seclusion.

6. Alor Island – East Nusa Tenggara

Tradition and diving excellence
Alor is a culturally rich island home to traditional weaving villages and tribal customs. Divers and marine photographers are drawn here for some of Indonesia’s most vibrant coral walls and macro life. The island’s rugged beauty and warm hospitality make it feel like a secret waiting to be uncovered.

7. Sumba – East of Bali

Waves, rituals, and raw nature
Sumba is known for its wide open spaces, megalithic tombs, and the Pasola festival—a traditional horseback battle. Surfers come for the legendary waves, while others enjoy the island’s raw landscapes, luxury eco-resorts, and low tourist density. It’s a strong contender for Bali’s more adventurous sibling.

8. Togean Islands – Central Sulawesi

Laid-back island hopping
The Togean Islands sit in the Tomini Gulf and are only accessible by boat—a factor that preserves their natural beauty. These islands offer colorful reefs, jellyfish lakes, and rustic bungalows. It’s a paradise for slow travelers who enjoy disconnecting from the world.

9. Nias – North Sumatra

Surfing and stone jumping
Known for world-class surf breaks, especially in Lagundri Bay, Nias has long attracted international surfers. Beyond the waves, visitors can witness the local stone-jumping tradition, where young men leap over tall rock towers as a rite of passage. The island’s culture is as impressive as its coastline.

10. Seram Island – Maluku

Trekking into the unknown
Seram is home to Manusela National Park, where trekkers can explore dense rainforests, rare birds, and hidden waterfalls. It’s a hotspot for birdwatchers and adventure travelers. Unlike its neighbor Ambon, Seram remains largely untouched by mass tourism.

How to travel responsibly to these islands

Traveling to remote Indonesian islands is a dream—but it comes with responsibility. Many of these islands are ecologically fragile and culturally sensitive. Here’s how to keep your impact low:

• Support local businesses: Stay at family-run homestays and eat at local warungs.

• Respect traditions: Ask before photographing people or ceremonies.

• Leave no trace: Dispose of plastic properly or bring reusable alternatives.

• Avoid coral damage: Don’t touch reefs or stand on them while snorkeling or diving.

Why now is the perfect time

With Indonesia investing heavily in tourism infrastructure beyond Bali, many of these islands are becoming easier to access—but they haven’t yet hit the mainstream radar. 2025 is a sweet spot for experiencing them in their raw, authentic form before they become the next big destination.

Whether you’re a diver, a beach bum, a hiker, or a culture seeker, Indonesia’s lesser-known islands promise more than just beauty—they offer serenity, stories, and soul.
