We went for this crossing and it was an adventure, head a little farther north towards Perquin. Before you climb the hill into the village head right on to dirt road. Ask for directions to "marcala". Keep following this dirt track for 15km or so until you find the El Salvador building where you can exit. The honduras building is further up the nasty road. Its simple no computers, no import just pay 3 bucks and have the police enter your name in their ledger. With no bike paper work we thought it might be a problem, but 3 military checks later it was ok, and when we exited Honduras at Los Manos they just waived us through !
