The afternoon boat runs the same route leaving Gili Air at 3PM and Gili Trawangan at about 3:30PM. The fare from either of the other islands to Gili Meno should be about Rp 20,000, but is prone to impromptu fluctuations.

From Lombok
Public boats depart from Bangsal between 8AM-5PM, take about 30 minutes, and cost Rp 10,000. They depart only when there are enough people normally a minimum of 15.

The boat office at Bangsal will though make sure you get dropped off by a Gili Trawangan-bound boat if necessary. A chartered boat from Bangsal to Gili Meno will cost about Rp 200,000.
