Glendora Holiday Lights is located between Gladstone and Juanita off Glendora Avenue. These are great to see from your car or after dinner for a quick walk. It is not crowded and there is no selling. If you live in the area this is a great place to take the kids. Would I drive out 20 minutes to come here, nope.
This park has a lot of hiking trails. Get your kids out hiking on any of the trails and then make your way back to the park. If your kids are older start at Bonnie Cove trail which is on the other side of the hill and make your way to the park, have lunch, and then hike back.
