In 1938 he and his wife travelled to the United States where he created a collection of scenes including around Niagara, the Potomac, Blue Ridge Mountains and the Californian and New Mexico deserts. Worrall also travelled to Greece and Italy, working as a stevedore to help fund the ventures, and some art from this period exists in private collections. By this time his creative work had moved away from mostly industrial and urban scenes to generally picturesque rural landscapes and included settings in the Lake District, Cornwall and Somerset. His depictions often included water, and he frequently used the technique of placing a house and/or tree in the foreground or middle distance. A good example of this is his painting of Stoodley Pike in Yorkshire, currently on display in Todmorden public library.
