Concierge.com's insider take:
Most of St. Lucia's beaches are on the island's west coast. Reduit, at the island's northwestern tip, is one of the best: long, sandy, and sheltered by tropical greenery. South of Gros Islet, it's absolutely packed with tourists, restaurants, and bars, but the northern part stretching to Pigeon Island (interrupted near Gros Islet by the waterway to the marina) is quieter and preferred by St. Lucians on weekends. Labrelotte Bay, which lies just south of Reduit and stretches between the East Winds Inn and Windjammer Landing resort, is also lovely.
South of Labrelotte Bay is Choc Bay, overlooking Rat Island. It's where some of the island's largest hotels are located, and has water-sports facilities. South of Choc Bay is Vigie, which runs parallel to the landing strip of George F.L. Charles Airport. It is fairly popular with St. Lucians, but it isn't the cleanest beach.
Marigot Bay, which lies about halfway down the west coast, is the beautiful sheltered bay was where Dr. Doolittle was filmed (the original one, with Rex Harrison rather than Eddie Murphy). Construction of a new resort, Discovery Marigot Bay, has recently been completed here. The small beach isn't great for swimming, but it's a good spot for water sports and has a sizeable marina.
Further south is Anse Chastanet—a gorgeous sweep of sand with spectacular views of the Pitons, which also boasts St. Lucia's best snorkeling. The beach is used by guests from the eponymous hotel above it, as well as those from other neighboring properties like Ladera and several smaller hotels. Just south is Soufrière: A long stretch of dark sand edged with palm trees through which you can see one of the Pitons. This is mostly a local haunt.
