It is between October to April.

Hi. Arambol is one of the north most beach of Goa and the airport is just in middle of Goa. Therefore, distance is quite big. As far as travel in goa is concerned, the only (literally) option available is to hire a cab or drive one yourself. I have been goa many times and always used either a rental cab or drove a self driven one. Public transport in goa is alomost non existent and if at all is there, hardly it suits to the tourist needs. So don't think much. Take a cab from airport. The cost might be between 1500 and 2000 inr. Alternatively, check with your hotel if they can arrange pick up.

Desaraat.

Airtel is working fine

Plenty gong on along the beach Usually live music You have to find out which bands are on where and when

I was staying at Candolim. So took a cab there. When u reach the beach, you have to walk through a mountainous area (there r small resorts n shop along this route), to reach the beach. It’s worth the effort.

It’s ok to go to Goa alone. Lots of friendly people there

I went in April and there was hardly any tourists on goa’s beaches so if you’re going alone you might get bored but maybe I’m mistaken
