Croatia is a world-renowned tourist destination to which many flock during the summer months. The main part of the tourist offer is based on the sun and the sea, given the availability of beautiful and diverse beaches throughout the Adriatic Sea, a great wealth of cultural heritage and many other accompanying contents. Unfortunately, because of this, there is a massive form of emphasized seasonal summer tourism oriented to coastal and island locations. As an attempt to alleviate the seasonal overload in cities and on the beaches, but also as an expansion of the tourist offer, this final paper proposes a new form of tourism that could redirect part of the tourist population to, different in terms of content, but also beautiful destinations in nature offered by mountaineering tourism, a subcategory of adventure tourism. In the last few years, there has been a growing interest in staying in nature, far from busy urban areas, and therefore there is an opportunity to include mountaineering tourism in the tourist offer as a supplement or alternative to the dominant forms of tourism in Croatia today. Mountaineering tourism can be consumed by a really wide population that may not even be aware of it yet. In this final paper, the basic values and attractions will be shown and explained, and the possible potential of mountaineering tourism in Croatia will be shown through a simple overview of basic terms related to mountaineering and a description of individual mountain features.
