Start on a track in a pleasant forested area.
This activity works well as a break during a hike.
The purpose is to get people engaged in non-visual, intimate encounter with trees, as well as the terrain.
The activity also works well as a trust-building activity.
The groups needs reasonable maturity, such that the blindfolded people are cared for (golden rule: a blindfolded person must always be holding someone else's hand - or a tree) - watch out for careless guiding especially from macho males.
For mature groups, a briefing may be enough; for less mature groups, do a demonstration.
In pairs, one is blindfolded. The blindfolded person is to be the tree-hugger.
The tree-hugger is lead through the trees and then placed next to a special tree. The tree-hugger touches the tree and tries to memorize its size, shape, location, texture, etc.
The tree-hugger person is lead back to the starting point, takes his/her blindfold off and tries to locate his/her tree.
Swap. Usually participants like to have a couple of turns at being blindfolded and trying to find a tree.
