Walking from Murcia to Sucina

Hi there.

I was near Sucina a couple of years ago, and decided on the challenge of walking from Murcia to Sucina.

I will be returning next month, and intend on seeing the challenge through.

Last time I went there, I went by car from Riquelme to Murcia, but I am wondering if there's an off-road route we can take, off the beaten route.

I'm not looking for specific route details in minutiae, but more that there are footpaths available.

Can anyone help, please?
