Missouri hides some good hiking behind a reputation for flat highways and one famous arch on a riverbank, and most first-time visitors never look past either one.
Almost everything here says yes to a leashed dog, from the state park system to the one national forest in the south. The historic sites scattered from the Ozark hill country up to St. Louis add even more ground to cover.
Gateway Arch is the national park most people think of first, and it turns out to be one of the friendliest, with leashed dogs welcome right up to the arch itself.
This guide lays it all out: the Ozark forest where the real miles are, the historic sites worth a stop, the state parks that reach nearly every corner of Missouri, and the Arch's easier grounds downtown.
Head for the Ozarks if you want the real hiking in Missouri, and Mark Twain National Forest is where that actually happens, mile after mile of it.
It stretches across the southern half of the state in scattered pieces, springs and hardwood ridges everywhere you look, more shade and quiet than you'd expect from a Midwest forest, and every bit of it welcomes a leashed dog.

One rule covers it all: a 6-foot leash on the trail, even out in the quiet stretches where you won't see another soul all day.
The Missouri State Parks system is the workhorse everywhere else, and it welcomes leashed dogs across the board, so you're rarely more than a short drive from a good walk no matter which corner of the state you call home.
Gateway Arch National Park is more a city landmark than a hiking day, but it's a real yes for dogs, welcome on the grounds around the arch itself.
Wilson's Creek National Battlefield, down near Springfield, adds real walking trail through preserved Civil War ground, open fields and timber both, all open to a leashed dog.
George Washington Carver National Monument, down in the southwest corner near Diamond, is a quiet stop with walking trail through the woods where Carver grew up, and it welcomes a leashed dog.
Ste. Geneviève National Historical Park and the Ulysses S. Grant site round out the historic stops, both welcoming and both worth a short visit if you're passing through. The Santa Fe National Historic Trail crosses the western part of the state too, more a historic route than a dedicated trail, but friendly ground wherever you catch it.
So plan your dog days around the Ozarks and the state parks, not just the Arch. That's where Missouri actually earns its hiking reputation.
Missouri's one national park breaks the strict pattern you'll find out west.
