We planned our latest trip to Austin around getting a reservation at Hamilton Springs Pool. Visiting this collapsed grotto has been on our Texas bucket list for almost two years now. Needless to say, we were ECSTATIC about the fact that we could finally get in and see this natural gem. It was everything I hoped it would be and MORE! The Travis County Parks Department requires reservations from May through September in an effort to preserve the natural space and monitor the amount of traffic it gets from visitors to prevent overcrowding and overuse. Unfortunately when we visited, we were not allowed to swim because of high bacteria levels, but it was still SO worth it to finally see the gorgeous watering hole in person. If you ever find yourself in the area, this is a MUST see.
