So, you have just 1 day in Rio and you want to spend it wisely? Well, despite from sounding "cliche", unless you really want to avoid the touristy things altogether, we actually DO recommend you see:
That's already a lot to fit in to one day. But at least you will get a very small taste of the Touristic Highlights of the city. Concerned you won't be able to figure it all out in such a short time? Ask us for help. We offer our own "Highlights of Rio" tour. When accompanied by a registered guide you bypass the regular tourist line-ups and we'll take care of the logistics for you.
