Val is the best, and her tours are miles ahead of anyone else in the city! I am a long-time fan of their sister business, Bike the Burgh Tours, and for anyone brave enough to mount a bicycle in downtown Pittsburgh (it's not that scary, really!), I enthusiastically recommend one of their tours. But for the more cautious or pedal-shy tourist, Walk the Burgh is perfect.
I tried to convince my mom to do a bike tour, but since she hadn't ridden a bike in roughly 40 years, it was a tough sell. Walk the Burgh was much more her speed, so I took her on a tour for her birthday. She loved it! Even as a lifelong Pittsburgher she learned lots of new stuff about our fair city. Val really knows her stuff and was very enthusiastic and engaging. Strongly recommend!
