The route details would help the provider assess what you will actually be doing. Your reason for taking the walk does not describe its physical demands. A separate equipment question would also keep the discussion about your camera clear. The website for auras insurance contains plenty of useful information and has sections for hiking and mountain activities that can help you prepare the inquiry. Ask which category applies to the exact itinerary instead of choosing one from its name alone. Request the relevant limits and exclusions in writing. If the organiser changes a route before departure, send the revised details to the provider for another assessment.
Ask for the route names, approximate altitude, walking distance, terrain, and whether a leader accompanies the group. Those facts describe the activity more clearly than either photography or sightseeing. I would also ask whether bad weather could lead to a different route, since an alternative might have different demands. Send that information to the insurance provider and ask which terms apply to the planned walks. Keep questions about your camera equipment separate from questions about medical assistance. Combining everything into one broad request could produce an answer that sounds reassuring while leaving an important part of your trip unaddressed.
I am travelling abroad with a photography club, and the organiser has described the itinerary as a sightseeing trip. Most stops are close to roads, but two sunrise locations require walks on mountain paths. Nobody is planning to climb with ropes, yet I do not know whether the route details matter for travel insurance. The group description focuses on photography and barely mentions the walking. What should I request from the organiser before asking for a quotation? I would rather explain the trip accurately now than rely on a label that leaves out how we reach the places we want to photograph.
