Transfers
Padangbai is the fastest crossing and the longest drive. That trade decides the day more than the boat does.
The crossing is the short part. Padangbai is roughly 1.5 to 2 hours from the southern resort belt.

Sanur
Factor the land legs. A two-hour crossing from Padangbai becomes a five to six hour door-to-door day once the drive is counted.
Choosing an operator
Established names on this corridor include Eka Jaya, BlueWater Express, Gili Gili Fast Boat and Wahana Virendra, alongside smaller outfits. This desk does not sell their tickets and has no stake in which you pick.

The strait builds chop through the afternoon almost daily. This is the cheapest comfort upgrade available.
Twin engines, visible life jackets, a real manifest. In wet season, a good operator is the one willing to cancel.
If Lombok is a stop rather than the destination, a private hull turns the corridor into a cruising ground. Send the dates and the desk will say whether that is worth it.
