Autumn flowering bulbs are a favourite at this time of year, but you generally have to have keen eyes to find them as they can be very small and well hidden. On the contrary the Autumn Buttercup can turn a rugged hillside yellow with its shiny, rich yellow, blooms. Autumn doesn’t necessarily mean colourful leaves about to fall, as many trees here are evergreen. The Narrow-leaved Ash seems to be the first to turn yellow with tall Poplars following shortly. The deciduous oaks may retain their leaves until the buds shoot again in the new year, unless strong winds shake them free.

I’ve been living in this lovely area of Western Andalucia for the last 20 years or so and dedicate most of my time to the running of English language tourist information websites for the towns of Cádiz, Ronda, Grazalema, the famous or infamous Caminito del Rey, and also Wildside Holidays, which promotes sustainable and eco-friendly businesses running wildlife and walking holidays in Spain. My articles contain affiliate links that will help you reserve a hotel, bus, train or activity in the area. You don’t pay more, but by using them you do support this website. Thankyou!
