Krause Springs.
What can you expect from the Texas weather in July? Just one more hot day ahead with two kids who are bored by sitting at home under air conditioner and doing nothing special. We had two options: a sea beach or some new place with cool water in a driving distance of a couple hours. The children voted for swimming in the cold water. So we went after the early breakfast towards Austin. It took us 3 hours of driving to get there.
