We do not make weather cancellations until the day of. We are located in the Texas Hill Country where rapid weather changes are the norm. It is not unusual for weather in surrounding areas to be inclement while at the same time being very nice in the Wimberley Valley. If there is light, scattered rain we may be able to continue as scheduled, if there is heavy rain with any lightening we will have to cancel. If we have to cancel we will give you a call on the day of your tour and give you the choice of a full refund or a rain check gift card to reschedule your tour.
