I've not seen one there but they do have buses to thunder valley , and the two casinos in Oroville plus cash Creek you can find out information if you call or go on line and search for casino bus rides most have pretty cheap rides and they were giving you a $10-$20 free play with the rides the more you have with your party the cheaper it gets, that's my findings so far good luck !!
There a cash creek bus call the casino for information
Not sure best to call and ask.
Im not sure about a charter bus to this casino. If they do have one, it probably stops at multiple casinos in that area, not just Colusa.
