Yacht Club Area. If you are staying near Tahiti Yatch Club in Arue, buses run from very early until at least 6 pm. Walk across the big sports field to Ave General de Gaulle then a few hundred meters east, stand on the pavement (sidewalk) in front of the funeral home/marble counter tops shop. Wave at any bus you see as they approach. They tend to run about every 20-30 minutes. The cost in Dec 2016 was 200xpf one-way and 360xpf return. The smaller buses go by the nearby Carrefour but this can’t be a 15 minute walk. The big buses stop in the same bus stand as the bus to Faa and Marina Taina. The small buses stop next to the town hall, the Marie.
Marina Taina. The bus stand for Marina Taina from Papeete is a block south east of the main market (marche)just around from Vodaphone. If your French is poor just say Marina Taina to the bus driver and he will tell you yea or nay. The Omotara bus or the Paea/Papara bus go by the Marina. The cost in 2017 was 200 xpf or 340xpf return. The bus drops you just in front of the Marina. Coming back just cross at the pedestrian crossing and look for the bus stop sign.
Walking in Papeete From the Papeete Marina to Fare Ute is 14 minutes at a steady pace. Ocean 2000 is twenty minutes as is Hyper Bricolage. Its similar from the bus stops if you’re coming from the out lying areas. Champion is about 10 minutes from Marina Papeete.
