Sounds like you've had an awesome trip mate an I'll be visiting Portugal in October. Our plan is to take the ferry from Portsmouth to Santander, spend 3 days riding the trails southwards and then turn around and head back north for a further 3 days.
Thought about riding through France but the addtional costs of hotels/fuel/tyres seemed to be more expensive than a return ferry crossing..........and of course, as was pointed out earlier, there are always the hen parties to look forward to
Gonna be a few of us, 2 Ktm 690 enduros, 1 KTM 990 Adventure and of course a couple of Teneres. There's 10 others doing the same crossing but they are heading way south for the Moto GP at Estoril..........couldn't possibly get their pretty road bikes too dirty
cheers
