Manado haritasında 14 Minibüs hattı

Mikrolet (blue, look for the small direction sign on top or behind the windshield) between Terminal Paal Dua and Lapangan.
The mikrolet usually does enter the Paal Dua terminals - you will find it around the Patung Kuda Paal Dua (Manado).

The mikrolet can be boarded at all along the indicated route. This is your cheapest ride to/from the airport - it passes in front of the gate of the airport.

PS. the numbers on the mikrolets aren't correct anymore, so look for the (very small) destination sign.
