Have been working on access paths around the property. We want to keep the land as natural as possible but we also want everyone to have access to various parts of the land. One of ways we have been doing steps down steep hills is to use large flat rocks from the area. They keep the area as natural as possible and look great. They will eventually start to grow moss since they are in the shade. Its a lot of work to walk each big rock to its final resting spot but I think well worth it in the long term. They will last a very very long time. No need to worry about wood rot with these stairs.
