Gave a quick search on maps and already found "Jarjeer Mule And Donkey Refuge" in Marrakesh, my kind of place to visit. Also added Ait Benhaddou to the list.
I was born, raised and still living in southern Brazil, and the further away I got from here while still in the country was southeast, in Sao Paulo, so my call is heavily biased, be advised:
My favorite place in the city I live today, Florianópolis, is called "Cachoeira do Poção", but in this city alone there are something like 50 beaches, a lot of trails to walk, dunes, portuguese era forts, lakes, nature, and a lot of different cultures from people that immigrated here over the last centuries, so a lot of different types of food to try. Great place to go sailing as well.
Some remarkable places goes as follows:
Aparados da Serra National Park - National Park with loads of canyons, waterfalls and wildlife.
Serra do Rio do Rastro - mountain range crossed by an super zigzagged road with an observation point on top.
Gramado - mountain resort town heavily influenced by german settlers - packed with attractions, but also one of the most expensive destinations around here. Best places to go are GramadoZoo, Mini Mundo and Mundo a Vapor. Best at winter time.
Treze Tílias - knockoff version of Gramado, influenced by austrian immigrants, best beer in Latin America. You want to come during Christmas to see children running from Krampus.
Pomerode - also a touristy town, it is the most german city in Brazil, if you speak german you are at home here. You wanna come during " Festa Pomerana".
Jaraguá do Sul - a religious destination on the top of Boa Vista Hill, called Chiesetta Alpina, has a beutiful scenery. Also in the city there is a place called "Pico Malwee Parque" that offers nice views overlooking the town, they have llamas over there, do not ask me why.
Blumenau - Oktoberfest.
Bento Gonçalves - the center of the country’s wine industry. If you are not into wine or alcohol, I would visit it for "Parque Da Ovelha" alone. Especially with kids or girlfriend.
Curitiba - the city is really a multy ethnic cultural center, lots of german, italian, polish, ukrainian, japanese, arabs and many others helped to create the most developed capital on Brazil, there are monuments to honor many of those. There are a lot of mainstream staples, but here I would highly recommend "Museu do Paraná", "Bar do Alemão", "Kawiarnia Krakowiak", "Passeio Público", "Parque Barigui", "Parque Tingui" and "Parque Tanguá", to say the least. City is a true gem, so much to see, so much food to taste, and so much to learn here.
Sant'Ana do Livramento - most cities in southern Brazil have some degree of "gauchesco" traditionalism, a kind of traditional culture from Brazil, Uruguay and Argentina. On every town I have ever been here there is a "CTG" - Center of Gaucho's Traditions - where these traditions are kept alive, with huge number of people attending regularly. This city probably has one too, but it is the place I felt most the tradition alive among the population, so I guess it would not need one. Festival Binacional de Enogastronomia is when you want to be here.
Lages - if going to Sant'Ana do Livramento sounds too far from the route, I would recomment Lages. On both you can go riding horses, hunting, eating traditional gaucho food and especially real churrasco (barbecue). "Festa do Pinhão" is when you are looking to come.
I have not even listed many waterfalls, peaks and trails over all these places, but southern Brazil has a really rugged relief, so most of the places you will go to are probably surrounded if hidden nature waiting to be explored.
Google "Tradicionalismo gaúcho", it is really interesting and it is probably one of the most valuable experiences from southern Brazil for anyone to have. Most brazilian people dont even knows this exists.
