Agua Hotels Riverside

Twenty-four kilometres up the Bensafrim estuary from Lagos old town, Agua Hotels Riverside occupies Quinta do Parchal on the riverbank, where the Algarve's Atlantic light arrives softer and later than on the coastal strip.

Three pools — two indoor, one outdoor — anchor the spa circuit alongside a steam room, sauna, and full treatment menu running from hot-stone full-body massage to body wraps. The outdoor pool faces the garden and sun deck; the indoor pools suit the shoulder-season months when coastal hotels close. A golf course sits within two miles, and bicycle rental at the desk opens the riverside path toward Lagos marina.

Check-in opens at 15:00; the airport shuttle removes the car-hire question for most guests. Rating of 8.8 across 1,472 reviews reflects the quiet riverside position more than the spa alone.
