Paramedics Jodie Burton and Dave Chittenden, along with pilot Justin Gloag, flew in to the camp by the Lochy River on Thursday morning.
They teamed up with paramedic Dan Bentley, who was a parent helper at the camp, to demonstrate winching in and out of the helicopter.
More than 60 year 8 pupils, accompanied by four teachers and six parents, spent three days in the area before returning by boat to Queenstown yesterday.
Mr Bentley said the visit complemented what the children were learning on the camp, including safety in the outdoors and first aid.
"If you do hurt yourself [in the outdoors] ... the rescue helicopter is your way to get out of that situation
... to show these kids what’s involved in that will provide a bit of familiarity for them."
Erin Bonnar (11) was surprised by the visit, having only heard the helicopter was coming that morning.
She was amazed the crew had already flown a mission to Dunedin and back before arriving at the camp.
Jack Lucas (11) said some of the survival skills the pupils had learned included crossing rivers safely and making stretchers and bivouacs.
Principal Chris Bryant said the crew’s visit was a "fantastic opportunity" to see them in action and ask them questions about their work.
