- Plant beech tree about 1m from inside edge of moat.
- Chop tree facing direction you want it to land
- Use your body to push the tree carefully into place
- Carefully build up the earth around the tree to 'lock' it in place
- Add a stair on the inside of your base
- Ramp the earth to make the opposite side easily climbable.
- Use multiple trees if you want to make a wider bridge – be careful not to damage trees!
