A tortoise wants its routes, not your guests
A leopard tortoise is calm when its world stays predictable: the same pen, the same grazing ground, the same sequence of basking, eating and retreating to its shelter. Visitors disrupt that only when they enter the tortoise's space, crowd its shelter or try to interact directly. Set a low barrier or gate across the pen before guests arrive so the tortoise keeps the whole of its territory while people watch from outside it. A tortoise that can plod its full circuit, graze and withdraw at will treats a gathering as background movement beyond the fence, which is exactly the level of interest you want.
Never lift, carry or hand-feed this tortoise
The visitor habits that genuinely upset a leopard tortoise are being picked up, being carried for photographs and being offered food from fingers. Lifting a large tortoise off its feet is frightening for an animal whose defence is staying grounded, and clumsy handling risks a damaging drop onto its shell or legs. Hand-feeding teaches it to snap at fingers and fills it with whatever guests happen to offer, which for a grass-eating species should not include fruit and kitchen scraps in quantity. State the rule warmly at the gate: look as long as you like, photograph from here, and let the tortoise come to the fence line if it chooses.
Scatter the day's grazing before guests arrive
Occupation for a leopard tortoise is measured in hours of slow foraging. Before visitors arrive, scatter hay, dandelion leaves, plantain and other safe weeds widely through the pen instead of serving everything in one pile, tucking some under the shelter edge and some across the far corner so the tortoise travels between finds. Add a cuttlebone to gnaw and a shallow water dish it can step into. A tortoise working a scattered pen is occupied for the whole visit, displays the grazing behaviour guests actually came to see, and has no reason to pace the fence line begging for handouts.
Keep dogs, noise and crowding outside the pen
A leopard tortoise tolerates people far better than it tolerates a dog nosing its shell or children climbing in to ride or pat it. Keep dogs on leads and out of the pen area entirely, even friendly ones, since a tortoise cannot flee and a single mouthing can injure shell and limbs. Position the gathering so the pen is at its edge rather than its centre, and give the shelter end of the pen a screen or board so the tortoise can be fully out of view when it wants. Soak the tortoise at its usual time in its usual tray, away from the audience, rather than making the bath a spectator event.
Signs this tortoise found the day hard
A leopard tortoise that coped will graze the next morning as usual. One that stays withdrawn in its shelter, refuses food for more than a day or two, paces the same fence stretch repeatedly or develops a runny nose and bubbling after a stressful, dusty or crowded event needs the arrangement changed and, for the breathing signs, a reptile vet promptly. Note which factor changed, such as a dog present or the barrier removed, so it is not repeated. Keeping the visitor-day routine in KinsLe through Care Teams, with named duties for the soak, the forage scatter and the barrier check, protects this tortoise's slow routine every time the house fills.
