Hamilton Pool Preserve is a historic swimming hole located 3/4 mile upstream from its confluence with the Pedernales River, which is right outside of Austin. Hamilton Creek spills out over limestone outcroppings to create a 50 foot waterfall as it plunges into the head of a steep box canyon. The waterfall never completely dries up, but in dry times it does slow to a trickle. However, the pool's water level stays pretty constant, even during periods of drought. No pets of any kind are allowed. Only a limited number of people are allowed to enter so arrive early, people wait outside and as people leave, others are allowed in. There are no lifeguards on duty so swim at your own risk. There are areas that get pretty deep.

Extended Stay America Premier Suites - Austin - Kyle

10/10 Excellent

"Everything worked great"

La Quinta Inn & Suites by Wyndham San Marcos Outlet Mall

10/10 Excellent

"We were comfortable, relaxed, and enjoyed our stay at La Quinta Inn and Suites San Marcos Outlet Mall. The lady at the front desk was very kind and attentive. The hotel room we stayed in was nice and clean, and the beds were comfortable. The free breakfast was good. They offered biscuits and gravy, scrambled eggs, eggs with bacon, sausage links, different types of cereal, apples, blueberry bagels, white and wheat bread, muffins, yogurt, fresh made waffles, juice, & coffee. We ate A LOT! There were quite a bit of other travelers staying there too. We also forgot our toothbrushes and they gave us some with toothpaste for free. The parking is large, and they have a clean outdoor pool (we didn’t have time to use it). All in all, I would definitely stay here again!"
