The way to the entrance runs through a stand of cedars where the air already turns cool. Inside, the cave holds a steady 17°C the year round, so the walk 100 meters below ground stays cool in summer and warm in winter.The cave stays at 17°C whatever the season, so carry an extra layer even in midsummer. Wheelchairs are lent free at the information desk on 1F of the Akiyoshidai Tourist Information Center and can be reserved in advance — but only part of the cave can be covered in one, so check the published map for the wheelchair-accessible area first. The same map shows the car parks, bus stops and restrooms. Whether a stroller can be taken round is not published.
From the foot of the bridge you can walk down to the riverbed, where a baby in your arms looks up at the five wooden arches from below - you get the bridge without crossing it. Infants cross free, and since the bridge is open 24 hours with no reservation, you can go around a nap.Arches 2 to 4 are stairs, so a stroller only gets you across the first and fifth arches, which have few steps; switch to a carrier to cross. Bags can be left at the Kintaikyo Bus Center baggage counter (500 yen per item, 9:35-17:00) or in a coin locker. The wooden deck is slippery in rain or snow, and the bridge is sometimes closed when the Nishiki river is high or the wind and rain are strong.
The display cases recreate something close to the snakes' natural habitat, and the living white snakes move about right in front of you. Their bodies are white and glossy with only the eyes red, so they stand out clearly inside the case. Sometimes newborns are on show.There is one diaper changing table inside the museum's multipurpose restroom. There is no bin for used diapers, so bring a bag to carry them out. For nursing, go to Kikko U-no-Sato, the cormorant facility next door in Kikko Park; its rest room has a nursing room and a diaper changing table. Children of preschool age enter free.
