Hotels with Gym in Picos de Europa National Park

"Hotel was acceptable, with clean rooms and ample breakfast. There is a feeling that it’s overdue a significant refurbishment, but comfortable stay overall. Important note: this might be a cultural difference, but the inclusive spa visit makes flip-flops AND swimming cap mandatory - if you don’t have your own upon arrival the hotel requires you to purchase both from the spa reception. This is somewhat unusual for a 4-star hotel in my experience, so worth specifically mentioning. "
