Two men were taken to The Queen's Medical Center early this morning after a head-on collision near Kualoa Ranch.

Police said that at 11:49 p.m. Saturday a 34-year-old Makakilo man in a 1995 Honda crossed out of the southbound lane, into the northbound lane and crashed head-on into a 2002 Honda driven by a 26-year-old Hauula man.

Both were taken to Queen's where they were listed in serious condition.

Alcohol may have been a factor.

The accident was just south of Kualoa Ranch. The road was closed during the investigation.
