Tourism for the observation of large cats, such as the jaguar in the Brazilian Pantanal and the puma in Chilean Patagonia, has emerged as a powerful tool to promote biodiversity conservation and sustainable economic development. This article explores the opportunities and challenges associated with this form of tourism, highlighting best practices and strategies for maximizing benefits and mitigating negative impacts. The analysis reveals that big cat tourism can provide significant economic benefits to local communities, creating livelihoods and raising living standards. However, it is crucial to maintain a balance between economic benefits and ecological sustainability. Implementing capacity limits, strict regulations, and sustainable tourism practices are essential to prevent the degradation of natural habitats and animal stress. Tourism education plays a vital role in promoting responsible behaviors among visitors. Orientation programs and the presence of experienced guides help ensure that wildlife interactions are safe and informative. Additionally, collaborating with academic institutions to monitor and research the impact of tourism on feline populations and their habitats is critical for making informed decisions. The involvement of local communities is another critical aspect. Initiatives that ensure communities directly benefit from tourism strengthen local support for conservation efforts and create sustainable income streams. Habitat restoration projects and anti-poaching units, funded by tourism revenue, can promote ecological recovery and reduce threats to wildlife. Diversification of tourism activities is also recommended to distribute pressure on wildlife habitats and extend the stay of tourists. In addition to feline watching, cultural visits, ecological trails and other activities can promote conservation and environmental education. Jaguar and cougar sighting tourism presents a valuable opportunity to promote conservation and economic development. Adopting sustainable tourism practices, education, and community engagement are essential to ensure that this form of tourism continues to thrive, benefiting both wildlife and local communities.
