Devon offers some of the UK's most diverse saltwater fishing, where anglers target species like conger eel, bass, pollack, and tope across its varied marine habitats. The Bristol Channel provides exceptional deep-sea fishing, with Lundy Island serving as a prime location for reef and wreck fishing, while the English Riviera's sheltered bays host prolific mackerel and bass runs. Recent years have seen Devon emerge as a world-class destination for Atlantic bluefin tuna, with charters reporting exceptional catches during late-summer and autumn seasons.

Anglers can choose from specialized fishing experiences including wreck drifting, shark hunting, and light-tackle bass expeditions. The coastline features accessible ports like Ilfracombe, Brixham, and Plymouth, each offering distinct fishing grounds. Beyond angling, Devon's waters are rich in marine life, with opportunities to spot seals, dolphins, and seabird colonies during coastal cruises. Trips range from family-friendly 2-hour mackerel excursions to 12-hour offshore adventures, with beginners receiving expert tuition and equipment provided.
