20 minutes SE of Comfort is Boerne which is full of beautiful Hill Country to sightsee and has so may fun activities for the whole family!
30 minutes N of Comfort is Fredericksburg which is another amazing place to sightsee and has plenty of great activities for the whole family! The art there is stunning, and the wine tours are amazing from what I have heard!
While about an hour from the venue, Natural Bride Canverns (and its wildlife ranch) are amazing to see and truly take your breath away!
This one is also an hour away but the riverwalk is a beautiful place to explore and I highly encourage touring the Alamo if you have time! Kristen's family helped build it and you can find their names in the barracks! (Cabrera Family)
