Byron's Boulder is a climbing area in the Mt. Shasta Ranger District of Shasta-Trinity National Forest in northern California, managed by the Forest Service. It sits close to the town of Mt. Shasta, about 2.7 miles from a weather station at Mt. Shasta with typical averages that give a sense of the conditions to expect. Late spring and early fall are the most comfortable times to visit. Typical averages from that nearby station show May highs around 68°F and September highs near 78°F, with lows in the 40s. July and August run warmer, with highs in the mid-80s and only a couple of wet days a month. Winters are cold and wet, with December and January highs in the low to mid 40s. Several other outings are within a short distance. Strawberry Valley and Sisson's Trail are both hikes about a mile away, and McBride Springs Campground is also about half a mile off. Mount Shasta itself, a mountaineering destination, lies roughly 1.7 miles away.
