The Mediterranean region attracts annually more than 400 million tourists. In recent decades, quad tourism has grown, favoured by poor regulations. Environmental impacts of off-road vehicles have been widely studied in the USA, but not in the Mediterranean. This paper addresses that gap through a literature review on the impacts of motorized recreation, and an analysis of the current implementation of quad tourism in the region and of advertising topics. Main impacts were reported on soils, vegetation and wildlife. We have registered 337 quad agencies in 20 Mediterranean countries, with important concentrations in some regions. Half agencies promote their tours with images driving out of the trails, 22% crossing rivers, 9% driving on the beach, 7% on dunes and 23% sell the activity as an extreme adventure. It is necessary a stronger authorization framework, including the environmental impact assessment of these activities, more involvement of tour operators in environmental protection and greater education of the participants about the impacts of off-road driving and the importance of their behaviour. Further research in the region is also convenient.

四轮旅游的影响：地中海的预防行动

地中海地区每年吸引超过 4 亿游客。近几十年来，由于监管不力，四轮车旅游有所增长。越野车对环境的影响已在美国得到广泛研究，但在地中海地区尚未得到广泛研究。本文通过对机动娱乐影响的文献综述以及对该地区四轮车旅游的当前实施和广告主题的分析来解决这一差距。报告的主要影响是对土壤、植被和野生动物的影响。我们在20个地中海国家注册了337个quad机构，在一些地区具有重要的集中度。一半的旅行社用驾车驶出小径的图片宣传他们的旅行，22% 的旅行社穿越河流，9% 的旅行社在沙滩上行驶，7% 的旅行社在沙丘上行驶，23% 的旅行社将这项活动作为一种极端冒险活动出售。有必要建立更强有力的授权框架，包括对这些活动的环境影响评估、旅行社更多地参与环境保护以及对参与者进行更多关于越野驾驶的影响及其行为重要性的教育。在该地区进一步研究也很方便。
