I haven't quite absorbed all of what I have experienced on this trip. The animals, birds, insects and vegetation we saw is almost overwhelming. I have gained a stronger appreciation for this world we live in because of this trip. I will definitely take another National Geographic G Adventures tour in the future.

A wonderful trip through a lesser travelled area of Indonesia. Our awesome CEO Mangun showed us the best of Indonesian culture and its people who were among the kindest, and most sincere I?ve ever met. The tour is quite travel heavy at the start but comes into its own in the final 2/3. The trip to Mt Bromo was my highlight!

I had a great experience. The group was very nice and I had a great time. I enjoy traveling with group because it is fun to meet likeminded travelers and make new friends from all over the world, however majority of this group was retired couples. It seems like G Adventure is starting to be popular among different age groups and as a result it might not meet my travel needs. I would like an option like 18-30something for 30 to 50 age group in order for me to be excited to travel with G Adventure again.
