I’ve seen some info about this route, but not nearly enough, so I thought I’d share what I did for anyone interested.
Cayenne - Saint-Georges: From Cayenne’s bus station, the TIG No. 8 bus goes to Saint-Georges. It’s a minibus run by a contractor you can call ahead to reserve a seat. I managed to get a spot the same day. It was parked on the other side of the river, across from the main bus stops. Price: 40 €, departures at 7 AM, 9 AM, 11 AM, and 3 PM except Sundays, depending on driver availability.
Saint-Georges - Oiapoque: Once in Saint-Georges, cross the river by canoe for 10 €. The canoe made a first stop on the opposite bank, then a second in the center of Oiapoque.
To enter Brazil, you’ll need to get your passport stamped. This can be done at the federal police station, less than 1 km from the dock, heading into Oiapoque.
Oiapoque - Macapá:
From Oiapoque, there are buses or taxis. Not knowing when the next bus would come, I didn’t want to wait, so I went back to the dock and took a 4x4, a kind of shared taxi, for 250 reals. I left around 4 PM and arrived at 2 AM in Macapá.
If I had to do it again, I’d take the bus—apparently, it has reclining seats and travels overnight to arrive the next morning.
Macapá - Santana
You need to get to Santana to take the ferry to Belém—tricky on a Sunday...
After waiting for a bus that was taking forever, I took a *carretera pirata* (unofficial taxi) on the advice of a local Brazilian. It took me to Santana for 10 reals (vs. 5 for the bus). The ride takes about 15 minutes from Macapá to Santana’s port. You can do this the same morning.
Santana - Belém
I bought tickets directly at the port when I arrived from one of the many agencies. I slept in a no-frills little hotel right by the port, run by a charming elderly couple, and boarded the next day at 9 AM. You’ll need a hammock to sleep if you’re not taking a cabin. The fare is 250 reals—it’s listed as 300, but they gave me a "discount" without me even asking. The trip takes 24 hours to Belém. There’s a small snack bar for those who didn’t have time to pack food.

Hope this helps someone avoid some of the hassle I went through!
