Why advertise in Summit Books? We are a mountaineering portal operating for mountaineering and nature sports with thousands of active mountaineers and thousands of summit registries. When looking at the membership profiles of the Summit Books, it is composed mostly of mountaineers or sportsmen who are engaged in mountaineering sports and the details, reports and photographs about the summits they made after these mountain climbing activities are shared through our system. For this reason, if you are selling products or services for mountaineering and nature sports, we think that advertising will be an important opportunity for you.
