There are no public trails starting directly at the cavern entrance. However, within the full park there are multiple trails. The shorter trails are at the actual springs and along the road going to the springs. And the 23 mile long North Sylamore Creek Trail crosses through the park down at the campground area. The entire park offers beautiful cliffs, crystal clear creeks, a good swimming hole, a great spring fed fishing lake, the place where the springs exit the cave system (a must see), and of course the cave tour itself, which in my opinion is a world class gem as far as beautiful caves go.
There are many hiking areas in blanchard. Some are three miles long but are clearly marked.
In the caverns its tours only. They do have an expert level, where there is only about 5 per group or so and requires a lot more crawling, off the beaten path so to speak, but it has a tour guide also. There is plenty of hiking outside by yourself.
