This Quest is designed to be completed by bike.
This mobile Quest will take you through the same steps as the printable Quest, and can record your clues as you go. However, if your phone turns off or loses connection during the Quest, data may be lost. You may want to write down the clues just in case.

Bike Safety Tips
- Helmets are required for youth under 18 and strongly recommended for adults
- Ride only on the right-hand side of the trail
- Leave the distance of a ‘ghost bike rider’ between bikes in your group to avoid contact
- Verbally announce the need to stop before slowing down and stopping
- Pull your bike off the trail and come to a complete stop at each Quest stop
