Here's the road guide from Margao:

From the Big Foot-Bolshe circle take the road leading to Raia. Continue along the Raia Road and cross the Sonsodo Garbage Disposal yard. Take the right immediately after Sonsodo and continue towards St. Alex Church, Curtorim. After the Church, continue along the Macazana Road till you reach Carmel High School and Church, about 1.5 kms from St. Alex. Take the left  directly opposite Carmel High School and proceed for about 0.7 kms along the perimeter of the Corjim lake to reach Arco Iris which will be on your left if you are on the right track.  If not, pls call us for help!
