Mountain tourism is growing globally, second only to coastal tourism. The COVID-19 pandemic led to a decline in international tourism, causing job losses and reduced government revenues. To ensure sustainable growth and improve citizens' wellbeing, many destinations promote domestic tourism. This paper investigates the role of mountain tourism activities in influencing domestic tourism consumption, focusing on economic dynamics and socio-cultural implications for destination management and policy formulation. More so, while there are many mountainous resources failure to diversify the mountain tourism activities for domestic market has led to declined consumption of tourism product by domestic tourists. This paper therefore explores the impact of mountain tourism activities on domestic tourism consumption in destination regions. It focuses on analyzing literature, case studies, and sustainable development through Scopus, Web of Science, SciELO, Google Scholar, published books and reports related to the topic. The paper suggests sustainable tourism strategies for mountainous destinations, balancing economic benefits and cultural preservation, to enhance domestic tourism and promote responsible tourism development.
