Essential Travel Tips

food

You absolutely *must* try St. Louis-style pizza. It's thin, cracker-like crust, cut into squares (party cut!), and uses Provel cheese, which is a blend of provolone, Swiss, and cheddar. Try Imo's Pizza for the authentic experience – it's a local institution!

transport

While St. Louis has public transport (MetroLink light rail and buses), getting around to many attractions, especially those outside the immediate downtown or university areas, is much easier with a car. Consider ride-sharing services like Uber or Lyft for shorter trips or if you're staying in a more walkable neighborhood like the Central West End.

money

Take advantage of free attractions! The City Museum, while it has an admission fee, is an incredible, unique experience that's worth every penny. Many of the city's best museums, like the Saint Louis Art Museum and the Missouri History Museum in Forest Park, offer free general admission, so you can save your cash for delicious toasted ravioli.

culture

Embrace the 'St. Louis pause.' Locals tend to be friendly but can be a bit reserved initially. Don't be afraid to strike up a conversation, especially at a Cardinals game or a local brewery, but understand that it might take a moment to warm up. A simple 'hello' goes a long way!

packing

Pack layers, no matter the season! St. Louis weather can be notoriously unpredictable. Summers are hot and humid, while winters can be quite cold with snow. Even in spring and fall, you might experience a wide temperature range in a single day, so a light jacket or sweater is always a good idea.

safety

Be aware of your surroundings, especially in less populated areas or at night. Like any major city, petty theft can occur. Stick to well-lit streets, keep valuables out of sight, and if you're unsure about a neighborhood, it's always best to err on the side of caution and use a ride-sharing service.

GoWithGuide Tours and Experiences

Getting Around St. Louis, USA

MetroLink Light Rail

The MetroLink is St. Louis's light rail system, connecting Lambert International Airport (STL) to downtown, the Central West End, and even into Illinois. It's a convenient way to bypass traffic, especially for airport transfers and reaching major attractions like the Arch or Busch Stadium.

Cost:$2.50 per ride (one-way), $5.00 for a day pass.
Tip:Download the 'Metro Transit' app for real-time schedules and ticket purchasing. Avoid waiting until the last minute to buy tickets, as machines can sometimes be slow. Be aware that service frequency decreases significantly after 9 PM and on Sundays, so plan accordingly.

MetroBus System

St. Louis's extensive bus network complements the MetroLink, reaching neighborhoods not covered by rail. It's ideal for exploring areas like The Hill for Italian food or the Delmar Loop for unique shops and entertainment.

Cost:$2.50 per ride (with free transfers within 2 hours), $5.00 for a day pass.
Tip:Use the 'Metro Transit' app to plan your route and track buses in real-time. Exact change is required if paying the driver, so have coins or small bills ready. Don't be afraid to ask the driver for confirmation of your stop if you're unsure; they're usually helpful.

Ride-Sharing Services (Uber/Lyft)

Uber and Lyft are widely available throughout St. Louis and offer door-to-door service, making them a flexible option for getting around, especially for late-night travel or when carrying luggage. They're great for reaching destinations not easily accessible by public transit.

Cost:Variable, typically $10-$30 for most intra-city trips, depending on distance and demand.
Tip:Check surge pricing during peak hours or major events (like Cardinals games) as costs can skyrocket. It's often cheaper to walk a few blocks away from a major attraction before requesting your ride to avoid localized surge pricing.

St. Louis City Scooters

Electric scooters are a fun and quick way to cover short distances in areas like Forest Park, the Central West End, or downtown. They're perfect for a spontaneous exploration or connecting between nearby attractions.

Cost:Typically a $1 unlock fee plus $0.30-$0.40 per minute.
Tip:Download the specific scooter company's app (e.g., Lime, Bird) and ensure you have a valid driver's license. Always park scooters responsibly in designated areas, away from sidewalks and building entrances, to avoid fines and local frustration. Be mindful of pedestrian traffic and local ordinances regarding scooter use.

Rental Cars

Renting a car offers the most flexibility, especially if you plan to explore beyond the immediate city limits or visit attractions spread out across the region. It's a good choice for day trips to nearby wineries or state parks.

Cost:Varies widely based on rental company, car type, and duration. Expect $40-$100+ per day.
Tip:Parking in downtown St. Louis can be expensive and challenging, especially during events. Research parking garages and their rates in advance. If you're only staying within the city center, consider if the hassle and cost of parking outweigh the convenience of public transit or ride-sharing.
