Ever wonder how that box of protein powder or the random pack of AA batteries shows up at your door twelve hours after you clicked "Buy Now"? It’s basically magic. Or, more accurately, it’s a massive orchestration of robotics, algorithms, and thousands of people working in a building the size of twenty-eight football fields. If you’re in the Columbus area, you’ve probably driven past the massive gray slab in Etna known as CMH1. It’s one of the few spots where you can actually walk in and see the gears turning.
Amazon fulfillment center tours CMH1 provide a weirdly fascinating look at the logistical backbone of modern life. It isn’t just a warehouse. It’s a high-tech playground where humans and robots perform a synchronized dance. Honestly, most people go in expecting a dusty storage unit but come out feeling like they just stepped into a sci-fi movie set.
You’ll see the "Amazon Robotics" floor. This is where the yellow "drive units"—which look like giant, heavy-duty Roombas—scurry around carrying vertical shelves called pods. The robots do the heavy lifting so the humans don't have to walk miles every day. It’s efficient. It’s loud. And it’s surprisingly colorful.

Why CMH1 is different from your average warehouse
CMH1 was a big deal when it opened in 2016. Located at 11903 National Rd SW in Etna, Ohio, it was one of the first in the region to lean heavily into the robotics side of things. Before these centers existed, workers spent their entire shifts walking up and down aisles, searching for items. Now? The items come to them.
The building spans about 800,000 square feet on the ground floor, but because of the mezzanine levels, the actual footprint is much larger. It’s a "small sortable" facility. That means you won't see kayaks or big-screen TVs here. Instead, CMH1 handles the small stuff—books, electronics, toys, and household essentials.
When you book one of the Amazon fulfillment center tours CMH1, you aren't just walking into a breakroom to watch a PowerPoint. You’re on the floor. You’re seeing the "stow" process where items are tucked into those yellow pods. You’re watching the "pickers" grab items with laser-guided precision. The sheer scale is dizzying. You might see a mile-long conveyor belt system that snakes through the air, carrying packages toward the shipping docks. It’s a literal labyrinth of cardboard and tape.

The technology that keeps Etna moving
The tech isn't just about the robots on the floor. It’s the software. Every single item in that building is tracked to a specific "bin" on a specific pod. The system knows exactly where every tube of toothpaste is at any given microsecond.
- The SLAM machines (Scan, Label, Apply, Manifest) are the MVP of the tour. These machines apply shipping labels to boxes using a puff of air. It happens so fast you can barely see the label land.
- The "Safety Third" vibe doesn't exist here; Amazon is obsessive about the "Green Mile," which is the designated safe walking path for visitors and staff.
- Computer vision identifies if a package is too heavy or if the tape isn't quite right.
What to expect when you actually show up
Don't just show up and knock on the door. That won't work. You have to book these in advance through the official Amazon Tours portal. They used to be strictly in-person, then went virtual during the pandemic, and now they've settled into a mix of both. The in-person experience is way better because you get the smell of cardboard and the hum of the machinery.
Wear comfortable shoes. Seriously. Even though you aren't working a shift, you’ll be doing a fair amount of walking on hard concrete. They also have strict rules about hair (keep it above the shoulders) and jewelry for safety reasons. They'll give you a headset so you can actually hear the guide over the roar of the conveyors.
The guides are usually employees who know the building inside out. They don't just give you the corporate lines; they can actually explain why a specific conveyor belt is spiraling or how they handle peak season during Prime Day. It’s a peek behind the curtain of the "Prime" promise. You see the pressure and the precision.
Is it worth the drive to Etna?
If you’re a tech nerd or someone who loves "How It’s Made," then yes. It’s eye-opening. You realize that your one-click order triggers a massive chain reaction involving hundreds of people and machines. It’s also a good reality check on the labor involved. You see the "Associates" (that's what Amazon calls the workers) at their stations. You see the pace. It’s fast.

Some people find the environment a bit sterile or intense. It’s very mechanized. But the sheer engineering feat of moving millions of items out of one building in Licking County is undeniable. CMH1 is essentially the heart of Amazon’s Ohio operations.
Common misconceptions about the CMH1 tour
People think they’re going to see a bunch of robots boxing things up. Not quite. While the robots move the shelves, humans are still the ones with the dexterity to pick a glass ornament out of a bin without breaking it. Humans do the "packing"—the actual folding of the boxes and the placing of the items.
Another myth is that it’s all automation. In reality, CMH1 employs thousands of people from the Greater Columbus area. The tour highlights the "man-machine" collaboration. You'll notice how the workstations are designed ergonomically to reduce strain, which is a big talking point for Amazon as they try to improve their safety record.
- Parking: There’s a massive lot, but it can be a nightmare during shift changes.
- Security: You’ll go through metal detectors. It’s like airport security but for cardboard enthusiasts.
- Photos: Usually, they’re pretty strict about no photos on the floor. You have to keep your phone tucked away.
Booking your spot and getting there
The tours fill up fast. Especially around the holidays or when school groups are in session. You’ll want to check the Amazon tours website specifically for the CMH1 location. If you can’t snag an in-person slot, the virtual tours are okay, but they lack the scale of seeing a four-story-tall mezzanine in person.
To get there from Columbus, you just head east on I-70. It’s a straight shot. You’ll see the massive "Amazon" signs long before you reach the exit. The facility is a cornerstone of the local economy in Etna, and the tour often touches on how the building impacted the local infrastructure.
Actionable steps for your visit
If you’re planning to check out the Amazon fulfillment center tours CMH1, follow this checklist to make sure you actually get in and enjoy it.
- Check the age requirements. Typically, kids need to be at least six years old to go on the floor. Don’t bring the toddlers; they won't let them in, and there's no daycare.
- Book 3-4 weeks in advance. Slots for CMH1 are popular because it’s one of the flagship "Robotics" sites.
- Dress like you're going for a hike. Closed-toe, flat shoes are mandatory. No heels, no sandals. If you show up in flip-flops, your tour ends at the front desk.
- Arrive 20 minutes early. Security takes time, and the tours start exactly on the hour. They won't hold the group for you if you're stuck in the parking lot.
- Bring your questions. Ask about the "Chaos" storage system. It sounds like a mess, but it’s actually the secret to their speed. Ask how they handle returns. Ask what happens when a robot breaks down. The guides usually love the specific technical questions.
Seeing CMH1 in person changes how you look at that brown box on your porch. It’s no longer just a delivery; it’s a piece of a massive, technological puzzle that you’ve finally seen the middle of.
