The second floor balances sweeping river views with recognisable city landmarks; Trocadéro gives the classic exterior frame. Book ascent tickets officially and allow time for two security checks before reaching your timed pillar entrance. Large bags, knives, scooters and non-folding strollers are refused, with no luggage storage; keep cameras inside railings. Private night photos are allowed, but professional use of illuminated-tower images needs the operator's permission.
