The eastern half of the park contains a play area for local children, which was opened in 2005.

The park is situated 75 m (246 ft) inland from Weston-super-Mare beach, on a site which was formerly part of a sand dune system of the Bristol Channel.

The species composition of this grassland includes the following grasses: Sand Cat's-tail (Phleum arenarium), Red Fescue (Festuca rubra), Sea Fern-grass (Desmazeria marina) and Cock's-foot (Dactylis glomerata).

Herb species present include Sea Stork's-bill (Erodium maritimum), Buck's-horn Plantain (Plantago coronopus), Rough Clover (Trifolium scabrum), all of which are indicative of a maritime influence, plus Wild Clary (Salvia verbenaca), Smooth Hawk's-beard (Crepis capillaris) and Pink-sorrel (Oxalis articulata).

Ellenborough Park supports two Red Data Book plants, Branched Horsetail (Equisetum ramosissimum) and Smooth Rupturewort (Herniaria glabra).
