Hi, HawkeyeJeff, Welcome to the forum!
Oh, my, that looks really lovely. Nestled in a park, along a forested river trail, just great! But it is a bit of a walk. Google maps says it’s 13 km from the center of Pontedeume to the monastery/church.
This wikiloc track would take you from a parking lot that looks to be about 8 km from Pontedeume, up to the monastery and then beyond through the park. Maybe get a cab to the start of these tracks where the parking lot is?

Itlooks like an off-road trail starts at the end of the DP-6902, and from there it’s about 10 km to the monastery. See these tracks.

Even if you don’t use wikilocs, take a look at the pictures that have been recorded. It looks like an absolutely beautiful walk. One idea would be to spend an extra day in Pontedeume and take a day hike out to the monastery, beyond through the forest, and then back to town. That wold probably be about 25 kms. I’d do it in a heartbeat if I were there! Thanks for pointing this out,
