アンテロープ観光時の持ち物について

制限の緩いところを使うのはダメですか

ツアー会社がそう言う以上従わざるを得ないでしょうが、日系でしょうか。日本語でもリュックサックOKなのが多いのですが。

GUIDED SIGHTSEERS TOUR
IMPORTANT DETAILS

Cameras are welcome but please no tripods, monopods or/and selfie sticks inside the canyon. We no longer offer the 2-hour Photography Tour available in years past.

Carseats are required for children 5 and under. Visitors are required to provide their own carseat or booster seat.

We do not recommend the tour for visitors with limited mobility. The canyon does not have wheelchair access and visitors must be able to complete the hike without assistance and descend 150 stairs to return to the transportation vehicles.

***Antelope Canyon is a sacred site to the Navajo and we expect our guests to treat it as such. Please be respectful of the space and do not do anything to desecrate the Canyon like littering or spreading the ashes of loved ones.

We appreciate your respect and cooperation. Thank you.

上記全てカメラはOKみたいですよ。レンズ交換式カメラを使う人は、それがどれほど邪魔になるかや交換のさいのリスクもわかっているでしょうが。むしろ、自撮り棒なんか持ち込もうとする人が絶対いて、そちらの方がよほど危険だと思います。
