Smiley Slopes is a climbing area in New Jersey, about 0.3 miles from the community of Cranberry Lake. It sits among a cluster of named climbing spots, with d. Smiley Face just 0.1 mile away and g. Walsh and h. Kovalcik each about 0.2 mile off. The area is close to the Sussex Branch Trail, a hike about 0.2 mile away, and Cranberry Overlook, about 0.9 mile away. The climbing here is mostly traditional, with 10 trad routes and two top-rope routes among the 12 listed. The YDS grades run from 5.2 to 5.8+, with the median at 5.5. Cast-less Point is the easiest route at 5.2, and BontiQtree is the top-rope option at 5.8+. For timing, late spring and early fall are the most comfortable. Typical averages from a nearby weather station show May highs around 71°F and September highs around 74°F, with July the warmest month at about 84°F. That station sits a few hundred feet lower than the slopes, so temperatures on the rock may run slightly cooler.
