You have three options...
I've tried all three types of travel, in various parts of the world - package is obviously the easiest, and quickest, and the most comfortable, if you're short of time / rich in pocket but you may miss out on the more personal side of Java. And you never know what adventures you might have miss if you had taken your own path. If you are travelling solo make sure you research safety issues and travel advice before setting off on your trip - this should be the case for all countries, not just Indonesia. We took a package as there were 5 of us, and we were time bound.
Day visit or Camping Overnight?
These trips are current, as are the prices, they're from www.panoramaujungkulon.com
We used this company for our package, and I have kept in touch with Thom ever since, I definitely will go back and camp one day. It was also one of the best trips I've ever experienced, the idea of sanding on newly formed land is incredible. Thom is offering a 50,000INR discount on all packages if you mention Heidi @ www.atravellingcircus.com. You can get in touch with him here firstname.lastname@example.org
no payment received, Just passing on my personal knowledge and experience of this company.
