What to do on the last weekend of July? We have a thought or two …

Geology of Stone Mountain, Saturday, 9 a.m., Stone Mountain State Park, Roaring Gap. No doubt you’ve looked at that strange forehead protruding from the ground, the one from which Stone Mountain gets its name, and wondered, How did that happen? Here, at this one hour program at the Hutchinson Homestead, is your chance to find out. And if you’re left at the end yearning for more, eager to know all about Stone Mountain, then stick around until 2 p.m. for “All About Stone Mountain.” (You can do some hiking in between to pass the time.) For more info on both programs and to register, go here.

Night Hike Along the Great Blue Heron Trail, Saturday, 8 p.m., Haw River State Park Iron Ore Belt Access, Greensboro. We love a night hike, and we especially love one where we’re not compelled to watch our every footstep to avoid rocks and roots in the trail. On the smooth-as-sandstone 3.8-mile Great Blue Heron Trail you’ll be able to focus on the wonder of the night. Bring a flashlight/headlamp with red or blue filter, bring bug spray and water. For more info and to register, go here.

Guided Hike: Balsam Nature Trail, Sunday, 11 a.m., Mount Mitchell State Park. Visiting Mount Mitchell, which tops out at 6,684 feet, is like visiting another world — so many unusual things to see at that elevation. Sunday, let a ranger explain what it is your seeing and why it’s there on this guided hike on the Balsam Trail. More info and register here.
