I'm considering Spain & Portugal land journey for October, 2025, but, I'm concerned about the #3 Activity Level. Do you have to walk on steep San Francisco-like hills with uneven cobblestones every day of the 14 days, or just some days or parts of days? I enjoyed the Scandinavia land tour, that was a #2 Activity Level, and I can walk 4 miles a day, but I don't have the best balance if I can't hold on to a railing or a wall. Did anyone find a walking stick helpful for balance? Does the tour continue on rainy days if the cobblestone is very slippery? I'd appreciate hearing from anyone who recently took this tour.
