You CAN go without bikes. The only thing is that you won't be able to walk all the way to the hot water side. But like Van says, those cats are all over so you'll do fine on foot. Just make sure that if you go in the afternoon, you give yourself enough time to walk back before they close. And have some drinks and snacks too to help with the walking.
One more thing... COMFORTABLE SHOES! The entire shoreline is rip-rap (softball sized rocks), so you'll need good boots/shoes that are strong and just watch the kids so they don't fall or twist an ankle.
