Quite an impressive scene if you can manage to do it without a guide or tour group around, you're surrounded by thirty metre tall trees that block out the sun leaving the forest floor in an eerie darkness.
Looking upwards, the trees form a breathtaking avenue towards the first of several temples housed within the forest. Beyond this first temple, the walk proceeds along a path to several others and past countless monkeys who may or may not be happy to see you.
Some visitors may want to arm themselves — some may want to flee. Whatever the case, try not to make eye contact, don't make any sudden moves and don't carry food unless you want attention.
A peaceful excursion if you can time your visit between the tour buses. Sangeh isn't on a main transport route, so access by public transport is difficult, but possible for those that are determined from Ubud or Tabanan.
