Ontario travel tips
1) Hikers lovers may not miss the North Etiwanda Preserve in Ontario | If you like adventures in a little rocky terrain, the North Etiwanda Preserve is a perfect challenge for you. Explore the 4.9-kilometre trail with great flora and fauna. If you have some energy left, head to Etiwanda Falls; they are located north of the main trail, go about 2 kilometres from the parking lot. You will get fantastic photos! |

2) Enjoy the hearty portion of Pastrami Melt at the Holiday Cafe in Ontario | If you have a good appetite, visit the Holiday Cafe at 931 N Milliken Avenue in Ontario. Locals always come back here because of their Pastrami Melt — a generous portion of pastrami meat, jalapeños, and fresh rye bread. |
3) Eat burgers from farm products in Ontario | The food at Farmer Boys at 10966 Central Avenue in Ontario is not fancy. They will offer you just ordinary burgers, salads, and French fries. But they get all these ingredients from local farms. Check it out! |
