Upper Trestles is the winter-wave counterpart to Lowers, producing a longer, steeper right-hander off the same cobblestone reef deposited by San Mateo Creek. It draws in W and NW swells that Lowers misses, making it a prime option during North Pacific winter storms. Notably less crowded than Lowers, making it a smart alternative when the main peak is a zoo.
