The singletrack sections may include natural rock features and some elevation changes.

Is the Bob's bypass Loop dog-friendly?

Given the varied terrain and potential length of your chosen loop, essential items include sturdy hiking shoes, sufficient water, snacks, a map or GPS device (like komoot's app), and appropriate layers of clothing for the weather. Insect repellent is recommended, especially during warmer months, due to the wetlands in the area.
