I've only been there once in April. It was a bleak place, with a totally inadequate access, which was a mudbath. Hopefully that has improved, but I suspect that in January it will be even bleaker and cold, and probably even muddier.
So I don't feel the need to make the trip this time. Maybe in the summer. What's there is remarkable but it needs far better public access than was the case when I visited.
