Ontario travel tips

1) Experience Lebanese food in Ontario

If hearty food and big portions is your thing, you need to visit Alina's at 2250 S Archibald Avenue in Ontario. Order juicy kebabs and falafel with a range of hummus, fattoush and pickles. This meal can be enough for the whole day.

2) Prefer Scandia to Disneyland in Ontario to avoid crowds

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.

3) Buy some rare plants at the Rancho Santa Ana Botanic Gardens near Ontario

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.
