Horseshoe is a resort on Lake Lyndon B. Johnson, near Marble Falls. There are three Robert Trent Jones, Sr. golf courses - Slick Rock, Ram Rock, and Apple Rock, and the new Summit Rock layout by Jack Nicklaus. The Nicklaus course is spectacular given that it's the newest, but it's private and tougher to get on.
Slick Rock was the original, being built in 1971. There's water on 12 holes, with the front nine routed through parkland type hilly land with exposed rocks bordering the fairways and over 70 bunkers. The back nine is a little more open and forgiving off the tee, with the fairways bordered by bamboo and pampas grass, and has the Million Dollar Hole, where the cart path passes through a waterfall. The course is a par 72, with a course rating of 72.8, and a 131 slope, and 6,800 yards from the tips.
Ram Rock opened in 1981 and is known as the Challenger. The course has more narrow and pinched fairways, with 60+ bunkers, water on ten holes and dry creeks on six with more elevation change to it. It plays to a par 71, 75.6 course rating and 137 slope at 6,900 yards from the back tees.
Apple Rock opened in 1986, with the routing over the higher land here with rock outcroppings and is more rugged than the others with a number of elevated tees providing views out across the lake. It's 6,800 yards, par 72, with a 75.4 course rating and a 136 slope from the tips.
