18th -The Swilken Burn, not more than 50 yards from the tee, is hardly a threat although from some tees - not the present Championship one - the bridge may get in the way of a low drive. The best line from the tee is on the Martyrs' Monument, between the R & A Clubhouse and the red stone Hamilton Hall. The road crossing the fairway at just under 250 yards is considered a hazard, but everything to the right of the fence along the right hand side is "out of bounds". The valley of Sin, a deep hollow along the front of the large oblong green, which slopes down from the back right-hand corner, converts par fours into bogey fives with great regularity. Most players should take at least one club more, for safety.
