Sumatra 7-Day Itinerary: North Sumatra in a Week

← Home

North Sumatra alone is enough for a full week. Orangutans in the rainforest, a volcanic lake the size of Singapore, and a city with more colonial and Chinese-Indonesian history than its skyline lets on. This route skips West Sumatra entirely and stays focused on the Medan–Bukit Lawang–Lake Toba triangle, which keeps road time reasonable and lets you actually slow down at each stop instead of spending the week in transit. Sumatra 7 day itinerary includes a balanced pace and practical pacing considerations for travelers.

Quick Answer: The 7-Day Route

• Days 1–2: Medan — arrival, city sights, onward transport
• Days 3–4: Bukit Lawang — orangutan trekking in Gunung Leuser
• Days 5–6: Lake Toba — Samosir Island, Batak villages, hot springs
• Day 7: Return to Medan for departure

Day 1: Arrive in Medan

Most international and domestic flights land at Kualanamu Airport, about 30 minutes from downtown by train. Spend the afternoon at Maimun Palace, the 1888 seat of the Sultanate of Deli, then walk over to Masjid Raya Al Mashun a few minutes away. If you have energy left, Kampung Madras (Medan’s Little India) is a good spot for dinner. See our Medan travel guide for the full rundown and our best hotels in Medan for where to sleep. This Sumatra 7 day itinerary provides practical context for planning your trip.

Day 2: Medan to Bukit Lawang

Head out early. A private car costs around IDR 650,000 and takes about 3 hours; the budget route is an ALS bus to Pinang Baris terminal followed by a local minibus (angkot) into Bukit Lawang, which runs IDR 55,000–125,000 total but takes 4–5 hours with the transfer. Full details, including which option makes sense for your budget, are in our Medan transport guide. Settle into your guesthouse and spend the evening by the Bohorok River — most lodges here are steps from the water. See where to stay in Bukit Lawang.

Day 3: Orangutan Trekking

This is the reason to come to Bukit Lawang. Book a half-day trek (around €55) if you just want a good chance of seeing orangutans, or a full-day trek (around €70) for more time in Gunung Leuser National Park and a better shot at spotting gibbons, macaques, and hornbills along the way. Multi-day treks that end with tubing back down the river are also available if you have the time and stamina. Our orangutan trekking guide covers what to expect, pricing tiers, and how to pick an ethical operator.

Day 4: Bukit Lawang to Lake Toba

There’s no direct public transport between Bukit Lawang and Lake Toba, so most travelers backtrack through Medan. Arrange a shared or private car through your guesthouse the night before — it’s a long day (7–8 hours total with the Medan transfer), so leave by 7am. Arriving in Parapat by late afternoon, catch one of the ferries across to Tuktuk on Samosir Island; boats run roughly every 30 minutes and the crossing takes about 45 minutes for around IDR 25,000. Check in and watch the sunset over the water — this is the payoff after a long travel day.

Day 5: Explore Samosir Island

Rent a scooter and spend the day working around the island. Stop in Tomok to see Batak Rumah Bolon houses and the old king’s stone tomb, then continue to Ambarita for the stone chairs where tribal trials were once held. In the afternoon, head up to the highlands near Pangururan for hot springs with a lake view, or simply find a quiet stretch of shoreline and swim — Lake Toba’s water is famously clean. Our things to do at Lake Toba guide has a fuller list if you want to fill the day differently. For where to base yourself, see best hotels at Lake Toba.

Day 6: Lake Toba at Your Own Pace

Keep this day loose. Options include Taman Simalem Resort for viewpoint cafes and forest trails, a boat trip to quieter parts of the shoreline, or simply resting — after five days of trekking and travel, most people are glad to have one slow day before the trip back. If you’d rather keep moving, a day trip toward Berastagi and Sipiso-piso Waterfall is possible but adds a long drive; only do this if you’re not tight on time the next morning.

Day 7: Return to Medan and Depart

Retrace the route back to Medan — ferry to Parapat, then car or bus onward. Budget 5–6 hours total and build in buffer before your flight; Kualanamu Airport is easiest reached via the airport train from Medan Railway Station rather than a taxi in city traffic. If your flight is late in the day, you can fit in a last meal of Nasi Padang or Soto Medan before heading to the airport.

Budget and Practical Notes

This route works comfortably on a mid-range budget of USD 40–70 per day per person including guesthouses, treks, and transport, or lower if you stick to budget guesthouses and public minibuses. For a full cost breakdown by category, see our Sumatra travel costs page. Dry season (May–September) gives the most reliable trekking conditions in Gunung Leuser; the wet season (October–April) is still workable but expect muddier trails and possible ferry delays on Lake Toba during storms.
