In 2024, the French amusement parks market generated approximately USD 3.25 billion in revenue and is projected to reach USD 4.27 billion by 2030, growing at a compound annual growth rate (CAGR) of 4.4% from 2025 to 2030. ([grandviewresearch.com](https://www.grandviewresearch.com/horizon/outlook/amusement-parks-market/france?utm_source=openai))\n\nFrance is home to several major amusement parks that attract millions of visitors annually. Disneyland Paris, Europe's most visited theme park, welcomed over 375 million visitors by 2022. In 2023, it generated a profit of $343 million for Disney. ([en.wikipedia.org](https://en.wikipedia.org/wiki/Disneyland_Paris?utm_source=openai)) Parc Astérix, another prominent park, achieved a record attendance of over 2.8 million visitors in 2023. ([en.wikipedia.org](https://en.wikipedia.org/wiki/Parc_Ast%C3%A9rix?utm_source=openai)) Le Puy du Fou, known for its historical theme, attracted 2.8 million visitors in 2024, making it the third most visited park in France that year. ([en.wikipedia.org](https://en.wikipedia.org/wiki/Le_Puy_du_Fou?utm_source=openai))\n\nThe industry is also witnessing technological advancements, with parks incorporating augmented reality (AR) and virtual reality (VR) attractions to enhance visitor experiences. Additionally, there is a growing emphasis on sustainability, with parks implementing eco-friendly practices such as recycling programs and energy-efficient operations. ([6wresearch.com](https://www.6wresearch.com/industry-report/france-amusement-park-market-outlook?utm_source=openai))\n\nHowever, the sector faces challenges, including rising operational costs and changing consumer preferences. In 2024, the average price of a hotel night in France increased by 26% since 2019, leading to shorter vacations and a shift towards budget-friendly accommodations. ([lemonde.fr](https://www.lemonde.fr/en/economy/article/2024/10/19/when-vacations-keep-getting-more-expensive_6729824_19.html?utm_source=openai)) Despite these challenges, the amusement park industry in France continues to be a vital and evolving part of the country's tourism landscape.\n\n\n## Rising Costs Impacting French Vacation Habits:\n- [When vacations keep getting more expensive](https://www.lemonde.fr/en/economy/article/2024/10/19/when-vacations-keep-getting-more-expensive_6729824_19.html?utm_source=openai) ",
