Depends what you are looking to do. Day passes are $20 ($16 for 22 and under) no rental gear included. Kids (5 and under) are $10 with rental gear. Rental gear is $8 with everything included. If you want to climb with ropes, youll need to take a belay class. Thats $15 and does not include the day pass or gear. But they have a "bouldering" section where you can climb without ropes and you do not need to take the class for it
When I went it was just me and my son, and it was like $40.
One family? Its individual to people so depends on how many kids or adults
