To get to Medewi you have to drive north west from Kuta for around 2-2.5 hours of hell traffic, best to leave early in the morning and beat most of it. There are also heaps of good river mouth set ups along the way, and rarely anyone surfing them. Just head towards Tabanan and keep following the main road.
Wet and dry season, early mornings are best as it gets easily blown out.

I’ve never had a problem with crowds up there, I think due to the distance from Kuta you have to travel. Also, because there are no night clubs for the party crew. You will also find the locals very friendly in and out of the surf. It is definitely a long workable wave, but you won’t find to many tube sections up there.
