Part way up the hill, to the south of the church at Navajeda, a 3m long cave was dug out to a crawl down to another section, excavated over a number of trips, and a low crawl down into a chamber. Just up to the left before the crawl through is a small chamber. There is abundant red mud and a number of good formations but all possible routes seem to close in except, perhaps, some unlikely high level holes which would need aids to reach.
