Swimming is now allowed in Onion Creek; call 512/243-1643 for current creek conditions.
Hiked the Onion trail. Long boring paced loop. But I did see a nice sized buck in the middle of the trail. We just stared at each other for 15 seconds. Really cool. I also hiked the rock house trail. Loved seeing the state champion cedar tree.
If it has rained a lot during the week, the falls will be great. The only downside is that makes the creek nearly impossible to cross and that's where the majority of the good trails are. When it hasn't rained as much, it's easy to cross the creek and get in 6-8 miles of great hiking.
