Plage de Locmaria is generally suitable for families, offering calm waters sheltered by the island's position. The beach has gentle slopes ideal for children, though conditions vary with tides and weather. No lifeguard supervision is typically available, so parents should closely monitor young swimmers. Currents can strengthen during tidal changes, particularly around the rocky areas flanking the beach. Check local tide times and weather forecasts before swimming. The sandy beach provides safe play areas when tide is out, making it popular with families visiting Groix.

Plage de Locmaria can be enjoyed year-round, though July and August offer warmest swimming conditions and longest daylight hours. Spring (May-June) and early autumn (September) provide pleasant weather with fewer crowds, ideal for beach walks and photography. The beach is particularly renowned for spectacular sunsets visible from its western-facing position. Winter visits appeal to those seeking solitude and dramatic coastal scenery, though swimming is only for cold-water enthusiasts. Tidal variations significantly affect beach size, so consult tide tables to maximize usable sand area during your visit.

Reaching Plage de Locmaria requires taking a ferry to Groix Island from Lorient (mainland France), with crossings operated by Compagnie Océane year-round. The journey takes approximately 45 minutes. Once on Groix, the beach is accessible by foot, bicycle (rentals available at the port), or island bus service during summer. Limited parking exists near the beach for those bringing vehicles on the ferry, though walking or cycling is recommended given the island's small size. The beach lies on the island's southern coast, roughly 3 kilometers from Port-Tudy.

Plage de Locmaria has limited on-site facilities, reflecting its quieter island setting. Basic amenities may include seasonal beach access, but visitors should bring supplies from Groix's main village. The village of Locmaria nearby offers a few dining options and small shops during peak season, though choices are modest. Most accommodations, restaurants, and services concentrate in Port-Tudy and Groix village. Visitors should stock up on essentials before heading to this beach. Several vacation rentals and guesthouses operate across Groix Island, requiring advance booking during summer months.

Plage de Locmaria distinguishes itself through its southern exposure and exceptional sunset views, unlike Groix's more famous convex beach (Plage des Grands Sables) on the northern coast. This beach offers a quieter, more secluded atmosphere compared to beaches near the main port. Its position provides shelter from northern winds while capturing golden evening light. The beach combines fine sand with dramatic rocky outcrops, creating scenic backdrops for photography. Being slightly removed from the main tourist circuit, Locmaria attracts visitors seeking tranquility and natural beauty over facilities and crowds.
