。
She went to Paris for the first time.
Literal
She [topic-は] first-time Paris [to-へ] went.
A simple travel sentence using the directional particle へ (toward/to) rather than に. While both に and へ can mark destinations, へ carries a slightly stronger sense of directionality — heading toward a place — whereas に focuses on the arrival point. 初めて (for the first time) functions as an adverb modifying the whole trip.
