Spend a fun day hiking, swimming, and zip lining on fabulous Kipu Ranch, a 4,000-acre working cattle operation. The setting is spectacular: a riverside National Wildlife Refuge surrounded by volcanic mountaintops. You'll take three different short hikes leading to beautiful waterfalls. Ride from trailhead-to-trailhead on a covered farm wagon pulled by a 4WD tractor. Swim in deep-water ponds and jump into pools at the base of mountain stream waterfalls cascading over black lava rock cliffs. Your optional zip line ride begins at an amazing 'Swiss Family Robinson-style tree house' built into a huge Banyan tree where you'll be given a mountain climbing harness and helmet, and will then walk through a labyrinth of aerial Banyan roots to arrive at the gated take-off area. Then zip line through the forest canopy, high above rivers and waterfalls at speeds of up to 30 mph. Note: Deli-style lunch included. Zip line riders must be comfortable with heights, at least 7 years of age and weigh between 80 lbs. and 275 lbs. Bring a jacket, wear a swimsuit and sport sandals or water shoes.
