This trail was only on my radar because of its name, because if you have a dog named Blanco, you are required by law to hike the Blanco River Trail and the Little Blanco Trail. Luckily, the trail ended up being much more than just crossing something off a list.
The trailhead is a little difficult to find, which may be by design, as there are no signs visible from the road to direct you to it's starting point, which is on private property. In fact, when we asked a local about directions to the trailhead, we got an answer that sort of implied they are a little protective of the area and a warning not to park in anyone's yard. Nevertheless, we found the TH and it was not near anyone's yard. However, there were very clear signs explaining the first one mile of the trail and hiker expectations for the one mile easement through private property.
After the first mile, the trail starts to resemble more of a wilderness trail, as one leaves the private property stretch. The trail was in great shape and there seemed to be evidence of relatively recent trail work. The only blemish was the amount of water on the trail. Due to spring run-off most of the trail had been converted into a canal for all of the excess water and we found ourselves waking in an inch or two of flowing water for most of the hike. The amount of water draining out of those mountains simply amazed me! In fact, some of the side drainages crossing the trail were nearly impassable due to the amount of water flowing down them. At about 3.5 miles in one gets to see perhaps the highlight of the trail, a nice overlook area on a sheer cliff that gives one some great views of a raging waterfall on the opposite bank of the river, a great spot for a break. On the way out, we ran into a group that was on their way to the same view point where we had stopped, so i am assuming this is at least a semi popular spot to visit. The hike back went quick, even with a worthwhile detour to the raging Blanco River, which I would suggest for some nice views of the river and canyon, as for the trail does not really follow that closely to the river's edge.
Notes: I lost my route for this trail, however, feel free to PM for specifics on driving directions...
