Side Quest & Recommended Routes

 

Take on a Side Quest!


Looking for something fun to do while completing your hiking miles? We’ve added a Side Quest! Hidden throughout Dublin are five mystery locations, and we’ve included pictures of each one in the caption. Your challenge is to find them! Each location can be found somewhere along one of Dublin’s trails or at one of our beautiful parks.

Once you find a location, take a picture of yourself at the spot and email it to Shulin at Shulin.Madrid@dublin.ca.gov. Be sure to include your name and where you found the marker. Each marker you find earns you one entry into our raffle. Find all five; and be entered to win up to five times! Prizes include a free entry to Dublin’s 5K, gift certificates for dinner for two, and much more!

You have until October 11 to submit your pictures. The raffle drawing will take place on October 23, and winners will be notified by email. Prizes can be picked up during T-shirt pickup.

Please note: To earn the official event T-shirt, you must still complete all 26 miles. This Side Quest a separate activity, so you can participate and enter the raffle even if you do not complete the full 26 miles. But completing the Side Quest does not qualify you for the T-shirt.

Below are the 5 locations to find and enter:

 

Happy hunting, and have fun exploring Dublin
