Ontario travel tips
Visit the Bucket Crab & Crawfish restaurant at 612 North Euclid Avenue in Ontario for a great seafood experience. They offer you to eat bucket-loads of shellfish the traditional way without any forks or spoons. Even if you are a beginner, choose from the clams, shrimp, crab, or crawfish; the staff are helpful and attentive and will equip you with the necessary gloves and instructions to minimize the mess.
Disneyland is a very crowded and time-consuming drive from Ontario. If you prefer a calmer atmosphere, choose Scandia. Yes, the park is not so large-scale, but it is so cozy and homey. Try the Scandia Screamer, the Swedish Swing or the Viking Ship! Tickets start at $17 depending on the set of attractions.
Just 15 minutes drive from Ontario you will find the Rancho Santa Ana Botanic Gardens, full of Californian native plants. You can even buy some to take home; salesmen give you some advice on how to maintain them. Then, explore the winding paths with squirrels, chipmunks, and birds.
