🗺 Indonesia in all its beauty: top spots and stable coverage across 17,000 islands

Indonesia isn’t just a country—it’s an entire world spread across thousands of islands. Everyone can find their own vibe here: from Jakarta’s futuristic skyscrapers and Java’s mystical temples to Sumatra’s untouched jungles and Komodo’s pink beaches.

How do you avoid getting lost in maze-like streets, book a boat to a remote island, or instantly share the view of Mount Bromo erupting? The main secret to comfort in Indonesia is stable internet.

With a Skyalo eSIM, you get reliable coverage across the country right away. Fly island to island, switch locations and time zones—your “trusted companion” will automatically connect to the best network so you’re always online, whether you’re on a volcano summit or in a secluded Lombok bay.

1. Mount Bromo, East Java

Mount Bromo is one of Indonesia’s most iconic volcanoes. Sunrise here looks almost otherworldly: mist, a smoking crater, and the endless Tengger caldera.
The hike starts before dawn, and travelers often rely on GPS maps to reach the best viewpoints.
This is one of the most popular searches for Indonesia volcano tour and a must-stop on any Java itinerary.

2. Komodo National Park, Flores

Komodo National Park is home to the legendary Komodo dragons and one of Southeast Asia’s most spectacular places.
It combines Pink Beach’s rosy sands, rolling savannas, and crystal-clear water with rich marine life.
Trips include boat tours between islands, so planning your logistics ahead of time is especially important.

3. Raja Ampa, West Papua

Raja Ampat is considered one of the world’s top diving destinations. With 1,500+ islands, turquoise lagoons, and coral reefs, it feels truly untouched.
Because the region is remote, route planning is especially important—transfers and boats are booked in advance.
It’s a key spot for anyone searching for best diving in Indonesia.

4. Borobudur Temple, Central Java

Borobudur is the world’s largest Buddhist temple complex and a UNESCO World Heritage Site.
Its multi-level terraces are decorated with bas-reliefs, and sunrise views over the jungle are considered among the most beautiful in Indonesia.
It’s best to plan your visit in advance due to limits on visitor numbers.

Ubud is Bali’s cultural and spiritual heart. The Tegalalang rice terraces, yoga centers, galleries, and temples create a slow-travel atmosphere.
The town is especially popular with digital nomads thanks to its mix of nature and strong infrastructure.
Ubud consistently appears on lists of best places in Bali.

6. Nusa Penida, Bali

Nusa Penida is known for the dramatic cliffs of Kelingking Beach and sweeping ocean views.
The island is less developed, with narrow winding roads—making navigation a key part of the trip.
It’s one of Bali’s most photogenic places and a frequent travel-cover star.

7. Lake Toba , North Sumatra

Lake Toba is the world’s largest volcanic lake, formed after a supervolcanic eruption. In the center lies Samosir Island, home to Batak culture, wooden houses, and ancient burial sites. The scenery here is calm, majestic, and almost meditative—mountains reflect in the water, and morning mist creates a feeling of complete seclusion.

Getting to the lake involves overland drives and ferry crossings, so navigation and checking timetables are especially important. An eSIM lets you save routes offline ahead of time and stay connected even in less touristy parts of Sumatra.

8. Mount Rinjani, Lombok

Mount Rinjani is Indonesia’s second-highest volcano and one of Southeast Asia’s most epic trekking destinations. The multi-day route takes you through dense forests and steep climbs to the Segara Anak crater lake with hot springs.

Before the climb, travelers register with guides, check weather conditions, and coordinate transfers from villages at the base. In the mountains, stable internet can be limited, so it’s best to activate your eSIM in advance—to download maps, routes, and essential info before the trek begins.

9. Gili Islands, Lombok

Gili Trawangan, Gili Air, and Gili Meno are car-free islands where you get around on foot or by bike. The vibe is laid-back: white beaches, clear water, and sunsets considered among the best in Indonesia.

Boats run between the islands, and schedules can change depending on the weather. With an eSIM, it’s easy to check up-to-date departures, book diving or accommodation, and stay connected without hunting for local SIM shops.

10. Jakarta

Jakarta is a modern мегаполис with skyscrapers, malls, and the historic Kota Tua district. It’s the country’s financial and business hub, where life moves much faster than on the islands.

Heavy traffic makes navigation a must when getting around. Ride-hailing apps, online payments, and ticket bookings only work with a stable connection. An eSIM lets you connect right after arrival and avoid expensive roaming.

13. Banda Islands

The Banda Islands are historic spice islands with colonial architecture, secluded beaches, and crystal-clear water. It’s a less touristy destination with a strong sense of history and calm.

Weather conditions change quickly, so surf forecasts are checked regularly. An eSIM provides access to up-to-date info without needing to find a local SIM.

17. Bukit Lawang, Sumatra

A small village at the entrance to Gunung Leuser National Park is the starting point for trekking to see wild orangutans. The jungle here is dense and humid, and routes cross challenging terrain.
