I am slowly performing maintenance on all my caches along the GR1. The cache on Stage 3, checked today, has been found only once in nearly 4 years. And it is in fine condition. Since this is a lengthy stage along the GR1, I decided to add a bonus cache. The location is right near the 1/4-3/4 post (depending on whether you are traveling east to west or vice versa).
Have fun, this is a lovely stage of the GR1!
