Emma Long Metropolitan Park
Time Out says
Emma Long Metropolitan Park is the only city-owned park that offers camping—and the only one that has a beach. Just off RR2222 and City Park Road lies the hidden gem—well worth the two-mile trek that winds down a wooded road before you arrive at the entrance to the park. Each of the 66 campsites has access to Lake Austin, and there are electric and non-electric sites catering to RV and tent camping. Rates are a reasonable $10-$25 dollars per night, with car fees of $5-$10. Activities at Emma Long include fishing, hiking, volleyball and basketball. Pets are permitted, but they must be on a leash, and there’s a 9.5-mile challenging outdoor motor bike trail and a boat launch so you can bring your own boat and enjoy the day on the lake.
