We did a self guided walking tour along the Algarve Coast with Mac Adventures. It was a great trip and I highly recommend it.
We started in Lagos
This wasn't the best walk of the tour. I wouldn't include it if I was planning this trip myself.
This takes you to the very most western point of the Algarve. The lighthouse was a great fortress, but the walking was neither good nor long enough.
