Excellent
Adrian, our guide, was very good, very knowledgeable about the area and made the trip fun and interesting. Pena Palace, Sintra, Cabo da Roca and Cascais were all great places to see. They were really busy places but it didn't interfere with our enjoyment. There was a lot more walking than I anticipated, especially uphill and on uneven ground but it was manageable and our guide was helpful as were our fellow travellers.
