Thymus camphoratus is an erect subshrub 15–30 cm (5.9–11.8 in) in height. Young stems have a quadrangular section, with very short hairs. Leaves are 6 mm–8 mm × 2 mm–4.5 mm (0.236 in–0.315 in × 0.079 in–0.177 in), ovate-triangular or rhomboidal, revolute in the upper half, acute or subobtuse, with whitish tomentose underside, with glabrescent or pubescent upper surface, densely covered with yellowish spheroidal glands. Inflorescence is 10–15 mm (0.39–0.59 in) in diameter, capituliform. Bracts are 7 mm–9 mm × 5 mm–8 mm (0.28 in–0.35 in × 0.20 in–0.31 in), broadly ovate, often pale pinkish or reddish, hairy, with scattered spheroidal glands, glandular hairs and marked veins on the underside. Calyx is 4–6 mm (0.16–0.24 in), flared; upper teeth are 0.7–1 mm (0.028–0.039 in), equal, not ciliated. Flowers are 5–8 mm (0.20–0.31 in), pink or purple; lower lip with large, subequal lobes. It has purple, exerted anthers. Fruits are 0.7 mm–0.9 mm × 0.6 mm–0.7 mm (0.028 in–0.035 in × 0.024 in–0.028 in), ellipsoid and dark brown. 2n = 30.[3]

Thymus camphoratus is native to southwest Portugal, particularly in the Southwest Alentejo and Vicentine Coast Natural Park. It inhabits heathlands and xerophilic scrub on stabilized dunes of limestone based sands, always close to the coast.[1]
