I use Atlas Obscura and Mt Sobek for tours. I did Machu Picchu with Mt. Sobek and it was great! I have done several with Atlas Obscura and am doing a tour of Vietnam with them in April. There are a mix of old and young in the groups.

I would suggest Portugal. Take a least two weeks. Start in Lisbon, do 2 -3 days with a stop in Sintra, and Cascais. Rent a car head north, stop off in Obidos, Nazare and head to the Douro Valley wine country, for another 2 days, tour the city of Porto (1 day) catch a flight to Faro and relax in the Algarve for the rest of your trip.

And time it for the Great Migration around May- early June each each year. The Great Migration is a yearly, cyclical journey of millions of wildebeest, zebras, and other animals across Tanzania and Kenya.

The migration is driven by need for food and water. The animals follow the rains, moving from the Serengeti to the Masai Mara in search of fresh grass. The migration is a clockwise loop that follows an annual cycle.

Also Zanzibar is also in Tanzania and has world heritage listed Stone City (where you can see birth place of Freddie Mercury. As a primary trading post for spice, silk and (sadly) slave trade routes for over a millennium, Stone Town has been a unique meeting place, blending African, Indian, Arabian and European cultures. The coastal areas have restaurants with tables on the shore line so you can eat fresh seafood with ocean water lapping at your feet. Taking a sunset cruise on a traditional dhow sail boat is fun.

Tanzania brought us the charming phrase "Hakuna matata" (Swahili for "no worries" or "no troubles").

DH would like to do a tour especially in a non English speaking country. We want to be active while we are still able. We are not looking for a 80 year old focused bus trip. Any suggestions. Assume price is no object (though it is a bit)

If you like ecotourism -

Magic birding circuit in Ecuador (visit four different altitudes in the Andes and see many rare birds in the cloud forest and condors in the peak plus pass through equator). Incredible biodiversity, changing of the guard in Quito is quite a spectacle, and we did not even get to the Galápagos Islands which inspired Darwin’s evolution theory.

There is more crime there now but the organizers of the magic birding circuit are very organized and savvy about protecting guests.
