E's HIDDEN AUSTIN! ALERT - Yep, a place that not many people seem to go, even though Wild Basin has been hosting "Haunted Trails" around Halloween in this place for years. I'm probably a dummy for talking about it here, but people ask me sometimes where to go hiking that isn't too far away, and I tell them "this is the place". Usuallly they scratch their heads and go "Hm, where the hell is that?" or "Not Enchanted Rock?" (uh, why did you ask me, then, buddy).
Wild River is indeed like Tracey said. Quiet, serene, and isolated - yet only 2 minutes from Bee Cave Road! If you go during unpopular times, it is certainly empty. It is not quite so far away from civilization though that, even during non-peak hours, you won't sometimes hear a faraway car, or people living somewhere nearby, in spots. This does not mean you ought not bring your cellphone. If you wipe out down there during a non-peak time, and are in a bind, even yelling your head off I reckon there's a chance nobody will hear you unless you got some belting power in your gut.
Now I'm not saying this is as bad as the signs I remember reading countless times on ski lifts in the northeast - "THE MOUNTAINS WILL BE JUST AS COLD AND LONELY AS THEY WERE 200 YEARS AGO. DO NOT SKI ALONE." I mean, come on, it's Austin. It's generally warm. And - it's only 3 miles of trails. But still, you know, be cautious people.
What I like best about Wild Basin is that not only is it less frequented than other hikey places around town, but the tree cover is just enough so that if it is blasting hot outside, you will still generally be shielded from the sun, even in the summer. And due to the rocky terrain where it lies, the bug count even with full bloom going on there is way less than a lot of other areas.
Other things of note: When there's been some rain in Austin, there's a cool little waterfall that will actually have water falling! you can hang out at. (I believe the full name of the place is Wild RIVER Basin, but the river portion is pretty small, and if it's wild they must be joking).
No pets.
The gravel rock driveway is pretty short. Just drive slow, you'll be fine.
The entry fee is pretty much donations on the honor system.
They have a little nature preserve HQ building that I think sells bottled water and will do little nature hikes, wherein they tell you what kind of stuff grows and lives in the basin. There's maps of the place near the entry to the trails, but if you go out there a few times, you won' t need one.
As they recommend, lock all things of note in your trunk when you go... the parking area is not monitored.
