Attractions and Tips

While in Saint Louis, treat yourself to a ball game at Busch Stadium, home of the Cardinals. To taste Saint Louis, spend time in The Loop, a six-block district of boutiques, galleries and eateries.

Before you leave, no trip to Saint Louis would be complete without checking out the Gateway Arch, a monument to western expansion that is nestled up against the Mississippi River.

To ensure you have a central hub for your Saint Louis exploration, book a hotel downtown, which will give you easy access to the Arch, the City Museum and Busch Stadium. For proximity to Forest Park, select Clayton or the Delmar Loop.

Saint Louis is slightly rainier than average, and the temperature varies with the seasons, so consider the time of year when packing.
