And once again we have arrived in this very nice town and today we greatly enjoyed the sea in the small bay below the Hotel Talasso. A great beach for surfers and also for people who like to jump through the waves. The view of the Flysch rocks is very impressive!

Today we came to this place again, just like in 2019, exactly on the Monday after the town festival. A note on the door of the basilica informs that it is closed during the entire festival from 1-9 September. Very unfortunate!

That is NOT A FOREST! It is a single plantation of eucalyptus. In reality it is a disaster painted green, green as hell.

While the guide focuses on routes designed to minimize traffic, the best time to enjoy the region's natural beauty with fewer people overall is typically during the shoulder seasons (spring and autumn). The weather is generally mild, and the landscapes are vibrant. Summer can be popular, especially along coastal areas, but inland routes and early mornings can still offer peaceful rides.
The routes listed in this guide are rated as 'difficult' due to significant elevation changes and distances, making them less suitable for young children or beginners. However, the region's emphasis on 'vías verdes' (converted railway lines) suggests that easier, traffic-free paths might exist outside of these specific challenging routes. For family-friendly options, look for dedicated greenways or shorter, flatter sections of trails.
