My personal faves are:
1.
Austin Ridge Bible Chuch Brand spankin new. IMHO, the most challenging course in all of TX... very technical & long w/ elevation changes on every hole. Give yourself @ least 2-3 hours to play the 20 holes & plenty of hydration. It's a total workout (physical, mental, emotional) playing this course. My body aches after playing this course like no other course I've ever played...
2.
Circle C Metro Park The most complete, well-groomed course in town. Dual concrete tees & signs on just about every hole. Two practice baskets. Challenging and very fun. A beautiful park.
3.
East Metro Park A very challenging course w/ dual concrete pads on most holes. Plenty of cacti & other prickly stuff in the rough. Also a beautiful park. **please note** They will lock you in this park if you don't get out before dark & there have been a few instances where they want to lock up before sundown. Morning/mid-day rounds out here are safest.. unless you are prepared to camp.
4.
Williamson County DGC A great course w/ dual concrete tees on just abt every hole. Precision game required. $1/ day (honor system) to play. Don't try to play this course if it has rained a few days prior b/c they close it down.
5.
Brushy CReek Sports Park IMO, the most fun & challenging 9 holer in the state. 3 par 4's & 1 par 5. Great if you don't have a lot of time & easy to turn it into 18 by playing twice.
6.
Rivery Park A neat 18 holer w/ good use of elevation. Dirt pads... little tricky to navigate.
If you want to check out the most well-known course in town try
Pease Park. It's a neat course, but not one of my personal fave's b/c of the high amount of traffic it gets.
Searight Park is also very popular & a lot of fun, but they are doing renovations & the back nine baskets are pulled at the moment.
Hope this helps. Drop me a pm if you'd like a guide while you are in town. Enjoy!!
