Downtown Houston has a second, quieter downtown 20 feet below the first. The tunnel system is a network of air-conditioned pedestrian passages, more than six miles long, that links 95 city blocks under the office towers of the central business district. On a weekday it's where downtown eats lunch, gets a haircut, picks up dry cleaning and walks between buildings without facing the heat or the rain.

Think of it as Houston's busiest weekday street: no cars, no sky, and closed by 6 p.m.

It's not a theme attraction, and it doesn't try to be. That's the appeal. Walking it gives you a feel for how Houston actually works on a weekday, and on a hot afternoon it's the most comfortable way to cross downtown. The catch: it keeps office hours, and finding the way in takes a little know-how. This guide covers both.

What the tunnel system is

Here's the part most Houstonians don't know: according to the downtown management district, Downtown Houston+, the whole network started in the 1930s as a single tunnel between two movie theaters. Over the following decades, building owners kept adding links between their towers, garages and hotels, and the result is the web of corridors you can walk today.

Because it grew building by building, the tunnel doesn't feel like one corridor. Expect a series of different spaces: polished food courts under one tower, a plain passage under the next, then a ramp, a few stairs and a shopping arcade. Sections run beneath private office buildings, which is why the hours follow the working day.

The free Downtown Houston+ map shows every connected tower, hotel and garage. The City of Houston notes that the Bob Lanier Public Works Building is one of the westernmost buildings with access to the system.

Tunnel hours

The tunnel is a weekday, daytime place.

• Weekdays: the City of Houston says access is normally from 6 a.m. to 6 p.m.
• Evenings and weekends: Downtown Houston+ says the tunnels close by 6 p.m. and aren't open on weekends or in the evening.
• The exception: tunnels that connect Theater District venues to their parking garages, which serve show-goers outside office hours.

Many of the shops and food counters down there run on a shorter schedule than the corridors, built around the breakfast and lunch crowds, so a late-afternoon visit can feel like walking through a closed mall. Building holidays can also affect access. Check the Downtown Houston+ tunnel page before you make a special trip.

How to get in

This is the part that trips up first-timers. You won't see subway-style entrances on the sidewalk. Downtown Houston+ says only two places offer direct access from the street:

• Wells Fargo Plaza, the tall tower at 1000 Louisiana St.
• McKinney Garage on Main Street, in the heart of downtown's Main Street corridor.

Every other entry point is inside a connected building. Walk into the lobby of a tower that's on the network, then look for the stairs, escalator or elevator down to the tunnel level. If you can't see it, ask at the lobby desk. If you're staying at a downtown hotel that's connected, the front desk can point you to the way down.

A few practical notes:

• Go during office hours. The building entrances follow the working day too, so a lobby that's open at noon may be locked in the evening.
• Accessibility varies. Because the network grew piece by piece, not every section has ramps or elevators. The official tunnel map marks accessible tunnel entrances, so use it to plan a step-free route.
• Your phone's map won't help much. GPS is unreliable 20 feet down, so carry the official map instead.

Maps and finding your way

Downtown Houston+ publishes a free Downtown Field Guide and Tunnel Map, linked from its tunnel page. Download it before you go. The map color-codes the named sections of the network, including the Downtown Tunnel Loop and tunnels under Walker, Louisiana, Travis, Rusk, Lamar, Dallas and McKinney streets, along with skywalks such as the Convention Skywalk. A Harris County tunnel is marked as limited access.

Underground, navigation works best by building rather than by street. Note which tower you entered and which one you're heading for, then use the map and any posted signs to work your way between them. If you get turned around, take the next set of stairs up into a lobby, step outside and get your bearings from the street grid.

What's down there (it's not just food courts)

Downtown Houston+ describes the tunnel as weekday "food, shops and services." The surprise is how much of a working day fits underground. You can find:

• Food courts and lunch counters. Coffee, breakfast tacos, sandwiches, salads and plate lunches aimed at office workers who want to eat and get back to their desks.
• Everyday services. Barbershops, dental clinics, fitness facilities, banks, dry cleaners, copy centers and newsstands.
• Small shops. Gift shops, flower shops and convenience stores.

Don't come expecting destination dining. The tunnel is good at fast, inexpensive weekday food and less good at anything else. For a proper meal, head back up to street level and use our guide to the best restaurants in downtown Houston.

Save this: a first-timer's tunnel route

The tunnel works best as part of a weekday downtown outing, not as a destination on its own. Screenshot this and follow it in order.

1. Download the official map first. Your phone's GPS will be guessing once you're underground.
2. Go on a weekday, late morning. You'll see it working, and food counters will be open for an early lunch. The lunch rush is the busiest and most interesting time to people-watch.
3. Start at a street-access entrance. Wells Fargo Plaza is an easy first entry point because you don't need to find your way through a lobby.
4. Pick a destination building. Choose a tower or hotel on the other side of the network and walk there underground. That gives the visit a shape.
5. Come up somewhere new. Surfacing into an unfamiliar lobby and stepping out onto a different street is half the fun.
6. Use it as weather cover. On a hot summer day or in a downpour, the tunnel is the most comfortable way to get between downtown buildings.
7. Finish above ground. Walk to Market Square Park or Discovery Green for fresh air.

One caution: in very heavy rain or a flood warning, stay above ground and follow official guidance.

Allow about an hour for a self-guided wander, or a lunch break if you're just eating. For more to do above ground, see things to do in downtown Houston.

Getting there and parking

Downtown is served by METRORail and many bus routes, which is often easier than parking. Our METRO Houston guide covers lines and fares.

If you drive, garages and surface lots are plentiful on weekdays, and some garages are themselves connected to the tunnel. Rates vary by garage and by time of day. Our downtown Houston parking guide explains garages, meters and event-day pricing.

Food nearby

Below ground, eat early: many tunnel vendors are built around breakfast and lunch. Above ground, downtown has everything from quick counters to some of the city's most ambitious dining rooms.
