From Danville you can reach scenic summit drives and trailheads that suit towable fifth wheel travelers, including the paved access to Mount Diablo State Park for panoramic overlooks and winding roads. The Iron Horse Regional Trail provides long, level stretches for bike and pedestrian outings with nearby parking where you can leave a rig for the day. Las Trampas Regional Wilderness has trailheads with parking and short hikes into oak-studded ridgelines that make for pleasant half-day trips from a basecamp. Interstate 680 connects these attractions efficiently, so you can plan routes with easy access and return to your campsite before evening.
