Nothing beats the heat on a hot afternoon like a dip in Barton Springs Pool. This natural spring pool is fed from an underground aquifer, keeping the water between 68°F and 72°F 20°C-22°C year-round.
Kayak on Lady Bird Lake
Rent a kayak. Zilker Park Boat Rentals is along the Barton Springs Creek. Just paddle down to Lady Bird Lake and see great views of Downtown Austin. Turtles are common in the lake and creek. Paddle over to the southern part of the Congress Ave. Bridge and hear the squeaking noises of the bridges 1.5 million resident bats don't hang out under the bridge-- bat guano is a problem.
