1) Take Highway 183 North from Austin for approximately 53 miles to County Road 208 in Watson. (If coming from the Austin airport, take 71 West to get to Hwy 183 North; mileage on 183 will be a little bit longer. Kifaru Animal Auction House (10831 South Highway 183, Lampasas, TX 76550), while burned down, the address will still work on Waze or MapQuest as a reference point.
Along the way you will go through Cedar Park, Leander and Seward Junction. Watson is 24 miles from Seward Junction. Watson is a very small community where 183 is intersected by RM 963. CR 208 is just North of 963.
2) Take a LEFT on County Road 208 West and continue for exactly 6.0 miles until you will see an unimproved dirt road (South Rocky Trail) on the right. Watch for the street sign for South Rocky Trail.
CR 208 is a narrow road with a) sharp turns, b) encroaching trees, and 3) all manner of creatures (i.e., cows, dogs, cats, coyotes, birds, others) wandering about with wild abandon, so drive cautiously. Along the way you will cross 7 cattle-guards and 2 low-water-crossings before coming to the unimproved road where you will turn right.
3) Turn RIGHT onto South Rocky Trail (the unimproved dirt road) from CR 208. Continue for 2.1 miles to the end of the road. The entrance to the land is the gate on the RIGHT side, at the very end.
PLEASE RESPECT the neighbors by driving slowly on South Rocky Trail (do not exceed 20 mph), to keep the dust down, and limiting damage to the road surface.
Along the way (within the first mile) you will encounter narrow, sharp turns, cross the creek again, so proceed slowly. The creek bed is solid rock and is usually easy to get through. At the end of the second mile, you will come to a pair of gates that cross the road. Ours is the one on the right.
