I organize one or two beginner trips for my local meetup group each year. I think it is important if it will be a beginner trip to actual make it one. What we experienced floks think of as easy and beginner is often well above real beginner level. I make sure the trips are easy, almost too easy. Many carry too much stuff as expected. But a 3 mile hike in will allow them to realize the benefit of a lighter pack without making the trip dangerous because they brought a giant flashlight with a spare lantern battery. The season is chosen so that a damp hoody will suffice as insulation but they will see others faring better with non-cotton. Etc...

Any issues that arise will not be remotely life threatening as the trip is just a step above car camping in difficulty. They are just wading into the water on these trips. They need to have fun and will eventually make it into the deep end if we don't toss 'em there and then rescue them.
