Ask about the route before the bag
Find out how much walking, climbing or exposure to spray the outing involves. Choose equipment you can carry comfortably while following the guide's instructions. A large kit can limit your ability to enjoy the route.
Don't assume someone else will carry it when the path becomes difficult.
Confirm equipment rules
Ask about tripods, professional shoots and any permits relevant to your plans. Drone use needs its own current permissions and rules; a general photography allowance is not enough.
Bring protection suitable for the equipment and conditions. Keep frequently used items accessible without unpacking the whole bag on a narrow path.
Plan a few deliberate stops
Tell the guide if photography is a priority so they can discuss timing and suitable stopping points. Keep companions informed about how long you expect to spend.
For a viewpoint such as Mount Gemi, visibility may not match your reference image. Take the equipment that supports the actual outing and accept that some photographs belong to another visit.
Rules, fees and opening hours change. Confirm anything that matters before you rely on it.
