Thank you for this information, I haven't yet decided what I will do when I reach Jaca.

... there is a bus that leaves from Jaca bus station at 9:30 am and takes you to San Juan Pena Monastery....From there you can walk the road to Santa Celia or take the bus back to Jaca....

The journey by bus is about 1/2 hour. The bus returns to Jaca at 7 pm., which means that you'll have to spend all day on the mountain and this may not be your cup of tea.
Worthwhile is visiting the old monastery, which is the first stop of the bus. If you don't return by bus, you can walk from here the steep descent (spread over 4 km) down to Santa Cruz de la Serós. Tough on your legs and dangerous at some places, but with incredible views towards the valley and the Pyrenées.
Not to be done shortly after or during rain. You can also return over the main road to Sta. Cruz. Either walk will take you approx. 2 hours. There is a scenic path from Sta. Cruz to Sta. Cilia, starting immediately at the exit of the village (to the left). If you walked more than 300 mtrs. on the main road you missed the turn off!
