A waterfall rappel operation

Building and running a two-drop waterfall rappel tour from trail to training.

We built and maintained the trail system, rigged a 30-foot and a 60-foot rappel with redundant anchors, wrote the operations manual, 22 standard procedures and the emergency plan, and trained every guide on the team.

Guests: 15,000+ on rope
Schedule: Two tours a day, six days a week
Record: Zero insurance claims
Our role: Trail, rigging, safety system, guide training, operations

Jungle trail rebuild

Turning slick, eroding jungle slopes into a trail guests can walk in the rain.

Log crib steps cut on site, a bog bridge and a plank boardwalk over the wettest ground, rock-armored tread where the mud never dries, and a bamboo handrail on the steepest section. Heavy logs were moved into place with rope and rigging.

Built: Crib steps, bog bridge, plank boardwalk, rock-armored tread, handrail
Materials: Logs cut on site, rock, lumber, bamboo
Our role: Design and build
