River cruise or walking tour?

Two ways to see one skyline

Ask a Chicagoan what a first-time visitor should do, and the architecture cruise comes up fast. They have a point. The Chicago River runs straight through downtown, and from a boat the towers line up along both banks while you sit back and listen. A walking tour cares less about the outline of the city and more about the buildings up close, from the terra cotta over a doorway to a banking hall under a glass roof. Neither format replaces the other, so the useful question is which one suits the day you have.

What the boat does well

No walk covers as much ground. A 90-minute cruise works all three branches of the river and passes 40-odd towers along the way, and you never leave your seat. The view is one walkers never get, the skyline rising in layers from water level as the bridges slide by overhead. For tired legs or limited mobility, that seat counts for a lot.

The cruise with the strongest following is the Chicago Architecture Center's river cruise aboard Chicago's First Lady, from ~$57. It runs about 90 minutes from a dock on the Riverwalk at Michigan Avenue and Wacker Drive, with a CAC-trained docent narrating. On Viator it averages 4.9 from 7,460 reviews. The catch is demand and exposure. Summer departures sell out, and the top deck can be hot in full sun or cold in a lake wind. You also see no interiors at all, only facades.

Wendella's 90-minute river architecture cruise, from ~$45, is a little cheaper. It leaves from near 400 N Michigan Avenue, beside the Wrigley Building. Its listing calls it the river architecture tour that started it all, back in 1935. It holds 4.8 from 9,739 reviews on GetYourGuide. Seats come indoors or on deck, which helps on a raw day. The catch is scale. These are big boats that fill up in summer, and like any cruise it never takes you through a door.

What a walk reaches that a boat cannot

Much of the Loop's early architecture stands nowhere near the water. The Rookery of 1888 and the Board of Trade of 1930 sit on LaSalle Street, several blocks south of the river and out of sight from any deck. Close by on Jackson Boulevard, the Monadnock shows how high a building could climb on brick walls before steel frames took over. The chapter told in where the skyscraper was born can only be seen on foot.

A walk also goes indoors. On the stronger tours you stand in the Rookery's light court and in the Art Deco lobby of the Board of Trade, and many routes finish under the Tiffany glass dome of the Chicago Cultural Center. None of these doors is promised, though. Lobbies close for private events or security, and the Rookery shuts on Sundays, so guides keep a spare stop ready. The Loop interiors you can walk into lists which tour opens which.

Then there is the city underneath. The Pedway, invisible from the river, is a web of tunnels and concourses linking dozens of downtown buildings, and one walk spends a good part of its two hours down there. Groups on foot also tend to be smaller. Inside Chicago caps its Pedway walk at 15, and reviewers of its interiors walk keep mentioning how few people shared their guide. A guest from Japan even found the walk more meaningful than the boat.

Cruise and walk side by side

A cruise costs a little more than a two-hour walk, and our price comparison puts both in one table with tips and transit on top.

Weather and the cruise calendar

The boats keep a calendar, and the walks lean on it far less. Most river cruises run from spring to fall, and only a few carry on into winter, Wendella among them, since its listing says it sails year-round. An open deck in January is still a cold place, with highs usually around 32 °F (0 °C) and a wind coming off the lake. On foot you can duck into lobbies between blocks, and the Pedway walk keeps you mostly underground, which one guest on a bitter day was glad of.

Summer flips the comparison. With July highs of about 84 °F (29 °C), a breeze on the river feels good if you find some shade on deck, while two hours on hot sidewalks can drag by midday. Rain spoils both, though a boat has a cabin and a walk only has doorways. The CAC runs its walks in any weather, with no weather refunds per GetYourGuide. For the whole year, season by season, see the best time for an architecture walk.

A cruise in the morning, lobbies after lunch

You can do both, and on a first visit we would. Each cruise takes about 90 minutes, and both docks lie within a few blocks of the Chicago Architecture Center at 111 E Wacker Drive, so a morning sailing leaves the afternoon free for a walk.

For the afternoon, choose a walk that does not repeat the river. The CAC's own Must-See Chicago walk, from ~$35, uses that building as its start and finish, but its route usually follows the riverfront past the Wrigley Building and Aqua, much of which you just saw from the deck. The CAC's Historic Treasures walk, from ~$35, heads south instead, toward the Palmer House lobby and the Reliance Building. Our pick, Inside Chicago's interiors walk, from ~$35, starts farther south by the metal horse sculpture on Financial Place, so leave time to get there from the dock.

If the only cruise seats left are in the afternoon, reverse the order. The interiors walk finishes at the Cultural Center, a short walk south of the river and the First Lady's dock, so an afternoon sailing is easy to reach once the walk is over.

Which one fits your trip

• One free afternoon. The cruise covers the most towers per hour, as long as it runs on your date;
• A love of old buildings. A walk, since none of the Loop's great lobbies can be seen from the river;
• Winter. A walk, ideally the Pedway route, because most boats have stopped for the season and an open deck is bitter;
• Children along. A cruise keeps small ones seated, though some lose interest over 90 minutes of narration; architecture walks with kids compares the walks that take strollers;
• Limited mobility. The boat asks least of your legs. Among the walks, Viator lists our pick as wheelchair accessible, while the Pedway route has staircases.

With two days in the city, do both. To try the streets before you pay for a guide, start with a self-guided Loop architecture walk.
