The boutique that can provide clearance is called “Chez Zeles” and is on the left side of the road when walking away from the pier “up” town. We asked several locals for a place run by “Lilli” and were met with very confused looks. Eventually we were directed to the police who knew where we needed to go, and unfortunately the shop was closed, so we took the bus ride to Grand-Bourg which was very easy. Price for the bus is now 2.50 Euro each. In Grand-Bourg, the customs office (“Doane”) is not very obvious or easily located; it does not appear on Google Maps and we needed to ask around. It is 2 buildings “down” toward the water from the tourist office, a rather nondescript yellow building with a green metal gate in front. Push the gate button and ask for the “Doane” and that you would like to clear in. They were thankfully in the office, and very friendly. They confirmed that the shop at “Chez Zeles” can also process the clearance. We enjoyed the trip to Grand-Bourg so it was not a problem – had a sandwich there and walked around, and then took the bus back to Saint-Louis.
