The Retreat at Coasters is first and foremost a place to relax with loved ones and engage with nature.  It's a place that supports one in doing as little as possible other than to enjoy the endless show that nature has to offer.   From the best seats in the house, perched on top of huge sand stone boulders up in the tree tops one doesn't have to do anything more than sit and watch.   A gentle stroll to a local swimming spot in the warmer months or a strenuous hike up to the fire trail and on and on through the Ku-ringai National Park may interest some.   A swim at the Basin, accessed in a number of ways from the property, will blow you away.
