Probably Felucia.

Mustafar

I think either Felucia or Kashyyyk, on JFO I died a lot of times because of those damn giant spiders

Its probably Dathomir. It's home to the Rancor, the Lesser Nydak, the Chirodactyl, the bane back spider, a bunch of different species of gaping spider, and the Nydak Alpha,

@Justsumtoast I agree that Dathomir should be included on the itinerary if you're planning a trip to terrestrial bodies with animals that will try to kill you.

All of these places are amazing and beautiful in a way, but maybe bring a blaster cannon, some grenades, a jetpack, and a flamethrower.

Theres also koboh with the bilemaw, bramlik, gorger, gorocco, the gorocco matriarch, mogu, rancor, rawka, shiverpede, the spawn of oggdo, and the vile bilemaw.

I know Endor is a moon, but it is pretty lush with plants and ewoks

There are really too many candidates to name, but I will go with Haruun Kal since it's the first off the top of my head.
