Our boutique hotel, Fonte do Foz was good for leaving to cross over the bridge to cross the Mondego River. (Tip: ignore google maps, you can Cycle easily down the esplanade to get to the bridge without having to go back through the town).
The cycle route was really good as for the best part it was mainly through forest areas. However in a small village, quite early on in the day, I fell off my bike (due to a car suddenly backing out – being clipped in and having disk breaks on your bike takes it toll occasionally, so back to trainers for safety and confidence !)
Then hubby had a flat tyre so a stop to change the tyre was required.
Nearer the end of our cycle, there were a few very steep uphill climbs (12 – 14% incline), which required us to get off our bikes (we still have heavy luggage!). But still, we found the cycling really good.
