I heard they organized senior to trip before. You can ask them for details. The trip I once attended is for adult and the tour speaks only English. This is a non-profit organization. The tour is good and very condense. But I want to remind you in those trips, people lives in hostel, which may be tough for seniors who are not strong enough. 5 s' n0 @ G# B ' |1 v) x% Y' ^* rGood luck!
