Trujillo to Guadalupe via bus
 

I'll be staying 2 nights in Trujillo later this month and would like to do a daytrip to Guadalupe. Unfortunately, I can't find out much information on bus service. A couple of my guidebooks state that there are 2 buses per day, but I don't know the name of the bus company and I don't know if the times would work to do a roundtrip in one day.

Does anyone have information on this?

Thanks, in advance.
