Kauai Zipline Age and Weight Limits, Side by Side
The age, height, weight and health rules of every Kauai zipline course, and of mountain tubing, from each operator's own site: who can ride where, and the course that fits a light child or a heavier rider.
The Koloa course takes the widest range of riders: from age 7, up to 280 lbs, with no minimum height or weight stated, and light riders go tandem. Kipu Ranch also starts at 7 but needs riders to be at least 4 ft tall and between 60 and 275 lbs. The Lihue backcountry course is the strictest: 12 and up, 100 to 250 lbs. Mountain tubing starts at 5.
Every rule below comes from the operator’s own site, read in November 2026, except Shaka Zipline’s, which come from the agency page adventureinhawaii.com because its own site did not load. Each operator enforces its own limits strictly, so check every rider before you book.

All read November 2026. On the Kipu safari day, the zipline weight range is over 60 and under 275 lbs.
A light child
For a child of 7 who is small for their age, the Koloa course is the one that fits. It sets no minimum weight; instead, depending on their weight and the weather, light riders ride tandem, tethered to a parent, a friend or a guide (koloazipline.com, November 2026). At Kipu Ranch the same child needs to be at least 4 ft tall and 60 lbs. Shaka Zipline’s 8-line tour takes no one under 10 or under 80 lbs, and its 5-line tour no one under 8 or under 60 lbs (agency’s figures). The backcountry course does not take anyone under 12 or under 100 lbs.
Minors ride with a parent or guardian at Koloa, and must be accompanied by an adult at Kipu Ranch; the backcountry pages we read do not say. At Koloa, bookings are made by adults aged 18 or over.
A heavier rider
The highest limit is Koloa’s 280 lbs. Kipu Ranch stops at 275 lbs, Shaka Zipline at 260 lbs (on the agency’s figures) and the backcountry course at 250 lbs. Riders are weighed and measured at check-in for Kipu Ranch’s Zip & Splash, and the backcountry course practises “strict adherence to the weight limit” (each operator’s own site, November 2026). If you are close to a limit, book the course with room to spare.
Health and fitness

| Poipu, Shaka Zipline (agency’s figures) | Pregnancy; any history of neck or back injury | Children under 18 need a legal guardian’s signature; children 14 and under ride with an adult 18 or older |
| Lihue backcountry | Pregnancy; serious medical conditions; recent back, hip or knee surgery | Good knees, hips and back; a short hike, an 8-rung ladder and landing on hard ground |

Each operator’s own site, November 2026.
None of the operators sets a maximum age; for tubing, the backcountry company states that there is none. Older riders meet the same fitness rules as everyone else.
The limits are each operator’s own, and the operator’s figure is the one that decides at check-in. Which Kauai zipline is best turns them into a choice by group.
