Solomon Airlines operates scheduled flights from Honiara to Fera Airport (FRE) on Santa Isabel. Fera is a grass airstrip on a small islet just off the southern coast, a 15-minute boat ride from Buala. Flights take around 30 minutes from Honiara; the schedule changes seasonally, so confirm with Solomon Airlines directly or through your accommodation.
There is also a weekly ship service from Honiara operated by the National Shipping Corporation of Solomon Islands, though travel times are long (typically 12–18 hours depending on stops) and schedules are unreliable. The ship carries both passengers and cargo and calls at several islands before Santa Isabel.
Bring sufficient cash from Honiara — there are no ATMs on Santa Isabel, and banking facilities are extremely limited. Stock up on any medications, snorkelling equipment, or specialized gear before you leave Honiara.
