MOUNTAINS
The Pacung mountain resort in the middle of Bali has breathtaking views. There are some very pleasant restaurants in the area to relax over a meal. The area is steep, so you will need to keep a close eye on the younger kids. There is also the Kintamani volcano to visit. The hawkers can be pretty persistent on tours so be prepared.
TEMPLES
Eddie and the family at Tanah Lot
These are everywhere and with a good tour guide you can learn a lot about the culture and history of the Balinese people. One temple is built on a beach - Tanah Lot - and it has a tour that ends at sunset so you can enjoy the view.
Anyone entering a Balinese temple will be required to show respect to the gods by dressing modestly. Skimpy clothing and shorts are unacceptable and you may be required to wear a sarong. These can often be hired at the temple. Sometimes you will be required to give a donation to the temple.
