Ontario travel tips

1) Try the best spaghetti in Ontario at Vince's Spaghetti

Family-run Vince's Spaghetti at 1206 W Holt Boulevard in Ontario is a must for you if you have a good appetite. According to the legend, Frank Cucci's uncle started this restaurant as a six-stool open-air French dip stand in 1945. He tempted passersby with great flavours. Now, spaghetti with meat sauce is a locals' favourite Italian meal here.

2) Check out wines around Ontario

Your visit to Ontario will not be completed without delicious wines from the neighbourhood. Check out the Mountain Vista Winery and Vineyards and The Wine Tailor. Both offer romantic nights out and wine tastings six-nights a week. The red Petite Sirah and sweet Port Styled are a must-try.

3) Experience camping in Ontario's landscapes

Ontario's nature is perfect for campings. For example, the Fairplex RV Park is a great option if you need seclusion with nature and modern conveniences. Prices start at $25 per night here.
