We did a the Kipu Ranch Zipline tour with 25 people on Kauai for a corporate retreat and had a great time! The guides were personable and accessible and had plenty of history and jokes and knowledge to share. They made an already amazing experience even better. Loved being on the river and Kipu ranch - which is such a beautiful area. Perhaps best of all, guides adapted quickly to each person's ability and skills so those who were a bit slower or nervous about things were gently encouraged but never made to feel uncomfortable - and for people who elected not to do portions of the day - they were easily accommodated with alternate options.
This would be a fun day with a small group of friends, and became one of the highlights of our trip to Kauai for a company gathering. Highly recommended.
