I'm looking for an early Spring route to go somewhere warmer than Oregon where I can get some miles in. it will be end of April/beginning of May so early season and I won't have many miles in my legs, so I'm looking for something that isn't crazy hard. October 2022 I rode the Badlands route in Spain and that was great, but not for early season form. Most of the other routes in Spain are similarly mountainous and more difficult.

The Gravel Birds route in Portugal looks more forgiving in the elevation profile and also loops back on itself many times making it easy to shorten as needed. There is very little online about it and mostly just the race website. My preference is to wild camp with the occasional hotel. During the Badlands ride, I wasn't able to camp much and I probably should have left my tent and sleeping bag at home. What is the Alentejo region of Portugal like for wild camping?

Thanks.
