Leaving the surf breaks of Kuta Lombok and the bustle of Mataram behind for the rugged, untamed landscapes of Sumbawa feels like stepping back in time. While Lombok has seen a surge in popularity, its neighbor to the east remains a frontier for those seeking world-class waves at Lakey Peak or the quiet majesty of Moyo Island. The journey across the Alas Strait is a rite of passage for travelers moving through the Lesser Sunda Islands.
This route is defined by the crossing of the Alas Strait, a stretch of water where you can often see Mount Rinjani fading into the distance while the hills of West Sumbawa rise to meet you. It is a journey favored by surfers with boards tucked under their arms and local traders moving goods between the islands. You can secure your seat for this island-to-island connection through GoAsia.cc.
Lombok to Sumbawa by Bus
The most practical way to reach Sumbawa from Lombok is a long-distance bus. These buses cross the strait by ferry, so you stay with the bus, walk up to the ferry deck for some fresh air during the crossing, and get back on the vehicle once it reaches the Sumbawa side. The crossing runs between Kayangan (Labuhan Lombok) and Poto Tano. ASDP, the state ferry operator, serves it with 2 ships and a schedule that is available 24 hours a day.[1]
Executive Class Bus Services
Booking platforms list executive buses on this route. On booking platforms the tickets cost about $6 to $9 (October 2026), depending on the operator and the drop-off point on Sumbawa.[2] Ask the operator whether the ferry passenger fare, which ASDP lists at Rp 18,800 for an adult on foot, is included in your bus ticket.[1]
The duration of the trip varies with traffic and, more importantly, the waiting time at the ferry port. ASDP gives the sailing time as about 2 hours.[1] Booking platforms list the total journey at 4 hours to 8 hours 30 minutes, depending on how far into Sumbawa you travel.[2] Night buses let you save a night of accommodation, while daytime travel lets you enjoy the coastal scenery of East Lombok.

Tips for Traveling from Lombok to Sumbawa
- Book in Advance: While buses run daily, executive seats can fill up quickly, especially during Indonesian public holidays or peak surfing seasons. Booking ahead gets you a seat on the day you want.
- Prepare for the Ferry: During the crossing you can leave the bus and head to the upper decks for views of the Alas Strait. Keep your valuables with you in a small daypack rather than leaving them on the bus.
- Snacks and Water: While some buses may provide a small snack or a bottle of water, it is wise to bring your own supplies. Options can be limited once the journey continues on the Sumbawa side.
- Motion Sickness: If you are prone to sea sickness, take precautions before reaching the port, as the strait can get choppy in rough weather.
- Arrive Early: Arrive at your departure point early enough to find your specific bus and store your luggage.
