The unofficial end to summer is right around the corner. But turn those frowns upside down! There is plenty to do in St. Louis this weekend to give summer the proper sendoff. Here are a few suggestions:

Nighttime Journey to the Top Tram Ride
The Arch and Old Courthouse switch to shorter, winter hours beginning Tuesday, Sept. 8, so enjoy the final chances to take a nighttime Journey to the Top tram ride. Through Monday, Sept. 7, the Arch is open until 10 p.m.; beginning Tuesday, it closes at 6 p.m. (The Old Courthouse’s winter hours are 8 a.m. to 5 p.m. daily.)

Two Mississippi River Excursions
The sightseeing and dinner cruises are spot-on ways to incorporate a unique riverboat ride in to your holiday weekend. On the sightseeing cruise, the captain will narrate your journey, highlighting the history of St. Louis. On the dinner cruise, sit back, relax and enjoy a delicious buffet feast while you cruise alongside the illuminated downtown St. Louis skyline.
