Just off of Willow Pass Road in Concord is a little amusement center: Pixieland. Although it is in need of repair or the very least a new paint job, the rides provide inexpensive amusement for the under 5 crowd.
Pros: Parking, Inexpensive entertainment for toddlers, Separate area for private parties and birthday celebrations.
Nice to haves: Updated exterior paint
Before embarking to Pixieland be sure to check their website for hours. As each ride requires tickets, purchase the Mini Fun Pack and let your toddler choose his/her rides. If you end up with some leftover, keep them in a safe place. Tickets never expire (like those arcade tokens) so remember them the next time your toddler needs to get out and release some energy. Afterwards, have a picnic in the park.
