How many people are in a Coasteering session?

This is a good question, and it depends very much on who the coasteering operator is.

The National Coasteering Charter [NCC] recommends a maximum ratio of one coasteering guide to ten clients. Its not uncommon for group sizes to be around sixteen with two guides.

While we respect the views of the NCC, we do feel that a one to ten guide to client ratio is too low, and groups of sixteen are too big! From our experience at Ocean Vertical it would be difficult for one coasteering guide to safely manage and lead ten clients and at the same time offer a authentic adventure experience.

Additionally we feel groups of sixteen, plus two guides, is just too many folks to take at one time into a natural marine environment – the environmental impact would just be too big.

We therefor limit our groups to six, and will sometimes also have two guides to lead the session. This is just our way of doing things, and no criticism of other coasteering providers. You can see details of our coasteering sessions here: Coasteering with Ocean Vertical
