Sumatra, the sixth-largest island in the world and one of Indonesia’s most diverse regions, is a destination filled with raw natural beauty, cultural richness, and incredible wildlife. Unlike the heavily touristed islands of Bali and Java, Sumatra remains relatively untouched, offering travelers the chance to experience authentic adventures. From active volcanoes and pristine lakes to lush jungles and traditional villages, Sumatra has something for everyone. Here are the five best places to visit in Sumatra in 2025.
1. Lake Toba – The World’s Largest Volcanic Lake
One of Sumatra’s crown jewels, Lake Toba is a natural wonder and the largest volcanic lake in the world. Formed by a massive volcanic eruption over 70,000 years ago, this lake stretches across 1,700 square kilometers and is surrounded by lush green hills. In the middle of the lake lies Samosir Island, almost the size of Singapore, which serves as a cultural and scenic hub for visitors.
On Samosir, travelers can explore Batak villages, learn about the traditions of the Batak Toba people, and visit ancient stone tombs and traditional houses. The island also offers homestays, cozy guesthouses, and plenty of opportunities to relax along the lakeside. Swimming, cycling, and hiking are popular activities here, and the laid-back pace makes Lake Toba a perfect escape for those wanting to slow down.
2. Bukit Lawang – Gateway to the Orangutans
Located on the edge of Gunung Leuser National Park, Bukit Lawang is one of the best places in the world to see wild orangutans. The village, nestled along the Bohorok River, serves as the gateway to treks into the rainforest, where visitors may encounter orangutans swinging through the trees, along with other wildlife such as Thomas leaf monkeys, gibbons, hornbills, and even Sumatran tigers if extremely lucky.
Bukit Lawang is also known for its eco-tourism efforts, with local guides emphasizing conservation and respect for the fragile ecosystem. Multi-day jungle treks allow adventurers to camp in the rainforest, raft down rivers, and immerse themselves in the heart of Sumatra’s biodiversity. For animal lovers and nature enthusiasts, Bukit Lawang is an unforgettable destination.
3. Mount Kerinci – Indonesia’s Tallest Volcano
For trekking enthusiasts, Mount Kerinci is the ultimate challenge. Standing at 3,805 meters, it is the highest volcano in Indonesia and part of the Kerinci Seblat National Park, another UNESCO World Heritage Site. The climb to the summit is demanding, usually taking two to three days, but the reward is unparalleled: panoramic views of the surrounding rainforest, crater lakes, and, on clear days, even the Indian Ocean.
The national park itself is a haven for wildlife, home to endangered species like the Sumatran tiger and clouded leopard. Trekkers often combine the climb with visits to nearby tea plantations and traditional villages, making the journey not only about adventure but also cultural immersion.
4. Padang and the Mentawai Islands – Surf and Culinary Delights
On Sumatra’s west coast lies Padang, a vibrant city known both as the gateway to the Mentawai Islands and for its world-famous cuisine. Food lovers will recognize Padang as the birthplace of “nasi Padang,” a dining style featuring an array of flavorful dishes such as rendang, spicy curries, and sambals. Eating at a Padang restaurant is itself a cultural experience, with small plates of food spread across the table for guests to choose from.
From Padang, travelers often head to the Mentawai Islands, a paradise for surfers. These remote islands boast some of the best and most consistent waves in the world, attracting surf enthusiasts from across the globe. Beyond surfing, the islands offer opportunities to connect with the indigenous Mentawai people, who maintain unique traditions including body art and shamanistic rituals. For those seeking both adrenaline and cultural discovery, Padang and the Mentawais are essential stops.
5. Banda Aceh and Weh Island – History and Tropical Beauty
In northern Sumatra, Banda Aceh is a city shaped by resilience and history. Known internationally for the devastating 2004 tsunami, the city has since rebuilt and is now home to memorial sites such as the Tsunami Museum and the striking PLTD Apung Ship, a 2,600-ton vessel carried inland by the waves. Visiting these landmarks provides a powerful insight into the strength of Aceh’s people.
A short ferry ride from Banda Aceh takes you to Weh Island, a tropical paradise ideal for diving, snorkeling, and relaxing. The island’s waters are rich in marine life, including manta rays, reef sharks, and vibrant coral gardens. Unlike heavily commercialized beach destinations, Weh remains quiet and budget-friendly, with charming guesthouses and beach huts along its sandy shores. For travelers seeking both reflection and relaxation, Banda Aceh and Weh Island offer a perfect combination.
Why Visit Sumatra in 2025?
Sumatra remains one of Indonesia’s less crowded gems, making it perfect for travelers looking for authentic, off-the-beaten-path experiences. In 2025, with eco-tourism and sustainable travel gaining more importance, destinations like Bukit Lawang and Lake Toba are focusing on preserving their unique ecosystems while welcoming visitors. The mix of adventure, wildlife, culture, and history ensures that Sumatra appeals to all kinds of travelers.
