Gallivant:

2. : to travel, roam, or move about for pleasure

It has some diverging connotations, but it does include idle roaming without a productive purpose:

Gallivant. g is a fine old word, meaning, in the words of the Oxford English Dictionary, "to gad about in a showy fashion, [especially] with persons of the other sex." To gad means "to wander around idly," so gallivanting translates more or less as "wandering around flirting"...
