Craving a funnel cake? Pop over to the Santa Cruz Beach Boardwalk (in the warm California sun- BOARDWALK) for some fried foods and wooden rollercoasters. There is also laser tag, bowling, and mini golf to keep you entertained!
Humble Sea is a brewery in the west side of Santa Cruz that is quite the scene. If you like hazy IPAs this is your place! There is usually a tasty local food truck as well.
If you are into hiking (or even a brief stroll), Wilder Ranch is right on the edge of town and offers beautiful views of the coastline. Keep in mind that there are no dogs allowed.
Abbott Square has multiple food and drink options in downtown Santa Cruz. It's a great place to grab a bite and potentially see some live music!
This is a world class aquarium. Monterey is ~1 hour south of Santa Cruz but worth the drive if you have the time!
