Transect a city walk

On your next visit to San Francisco (or if you live there) walk across this small city on the SF Crosstown Trail. Even though I have lived in or near San Francisco for forty years, I discovered all kinds of gems, and stunning views that I had no idea existed. The route is engineered to pass through as many neighborhood parks as possible, with unexpected turns, and hidden treasures. Although you can do its 17 miles in one long day, we divided it into multiple days, ubering back to our start place. The entire walk is enjoyable, safe, and endlessly surprising. Download the app so you can easily follow the trail on your phone. For locals, the trail runs from the new Candlestick Point Park to Land’s End national park. If similar transecting crosstown walks exist for other great cities, let me know. — KK
