* Περιπέτεια (peripéteia): This is probably the closest and most common translation. It implies a risky or exciting journey or experience, often with unforeseen events. This is your go-to word in most cases.
* Δράση (drasē): This means "action" and could be used if the adventure involves a lot of physical activity or excitement.
* Εξόρμηση (exórmisi): This translates to "excursion" or "outing" and is suitable for a shorter, less perilous adventure.
* Κίνδυνος (kindynos): This means "danger" or "risk," and is appropriate if the adventure is particularly hazardous. You wouldn't use this on its own to mean "adventure," but it could be part of a phrase describing an adventurous situation.
Therefore, περιπέτεια (peripéteia) is generally the best and most versatile translation for "adventure" in Greek.
