The actual distance up Lulu Pass Rd. to the turn off/parking is only about 2.3 miles. A good landmark for parking is where the Goose Creek Jeep Trail branches off to the right. Park here (unless driving a 4X4) and take the hard right there to continue to the trailhead 1/2 mile further down a rough road and back across Fisher Creek. There is a well marked trailhead there for Lady of the Lake trail as well as a parking area for 4X4 vehicles.
for those with 4x4 vehicle, you can continue north to round lake. about .3 miles past round lake there is a spur trail from the main road that cuts down (north easth) to the lady of the lake trail (1.3 miles i think). This would shave a few miles off the approach.
