Basecamp at a AirBNB in Soldotna area and then book your own charters. Pick a day to do a halibut trip out of Deep Creek, Fish the Kenai for reds off the bank on your own or get a guide. A day trip out of Seward for silvers and rockfish.
All these are easily done with a van to transport your crew.
MId/late July is the most popular time to be here for fishing, so book early, lodging and the good charters will fill up a year in advance.
