This is actually a trick – there is no trail map for this hike.  However, I found a pretty good set of directions at this link.

• You Google the Lost Creek Country Club and map out the directions
• Find a spot to park on Bend of the River Drive just before it crosses Barton Creek
• Look for the start of the trail just under the bridge
• Hike a short distance to the big flat rock in the middle of the Creek
• Quickly look for a convenient spot to ford Barton Creek
• Pick up the dirt trail on the other side
• Follow this sandy, tree covered trail for about a mile until you run into the waterfalls on Lost Creek
