It takes about 50 minutes to ride to the top of the Cynwyd Heritage Trail and then another 20 minutes or so downhill into the far reaches of Manayunk. You’ll likely want to stop on the bridge at a couple places to take a pic or two, especially of the sunset or moon rise.
You can’t beat this during a rush hour ride. Hardly any cars or vehicle pollution on route to deal with and the scenery is just beautiful! There are some hills involved, for sure, but nothing too difficult that a steady pace can’t handle. It’s so worth it!
For night time riding make sure you have a really bright bike light. I love my 600 lumen NightRider (600 lumen setting for 1.5 hours, 400 for 3, and 275 for 4.5. Also includes an annoyingly very bright flasher). Particularly handy when I want to ride fast and be able to clearly see the road quality details in far enough advance time to react well within reason. Cars and trucks down the road will often move over because they aren’t sure what vehicle could be so bright and so opt to get out of your way. Kinda inverts the situation for us cyclists!
