If you are spending any amount of time in some of California's best cities then let these guides be an inspiration for where to start your exploration. Some of the cities have more recommendations then others, but all of them are full of unique adventures and will continue to grow as I explore more. Please leave your recommendations in the comments of each city if you have a spot you think I should check out and have fun exploring.
A day trip to Catalina Island is a fantastic way to clear your head and experience island life a short one hour boat ride from Long Beach. This post gives you a bunch of examples for what to do while there.
While less barren then Mojave National Preserve, Death Valley National Park is full of wonders strewn through its diverse landscape of unique features.
This barren desert and man-made lake cater more to the offbeat adventurers, but if you give it a chance you should see its beauty as well.
Whether it is eating, paddleboarding or hiking, a trip to South Lake Tahoe can be a great long day adventure.
Yosemite is the gem of the National Parks system and it is located right in the heart of California. Spend the day soaking in waterfalls and marveling at Half Dome.
