January isn’t really the best time to visit Bali - doesn’t mean you can’t have a great time. There’s tons of things to do: waterfalls, hiking mt. Batur, bike ride through rice fields and cooking classes are popular. Most of this you can find close to Ubud.
Just be aware Ubud is really, really, really busy. You’ll want to stay somewhere you can walk to restaurants and markets- or if you have a licence and your insurance covers you: rent a scooter.
All that being said: I’d go for an extra week en RA instead - it takes such a long time to get to RA, that I’d just rather stay there longer. Or go somewhere with a direct flight to Sorong.
I know there’s sometimes a direct flight between DPS-SOQ, but right now people in the RA fb group is complaining they’re getting their flight cancelled and now has to fly via Makassar.
@GF99/99 we last visited Bali in 2022 and even though we thought Kuta was really not to our liking, Padang Bai was lovely.
Have you been to Permuteran and Amed or Tulemben recently and are they getting overrun by tourists as well or is it more the south that suffers?
