Ashton Lagoon | Union Island

Ashton Lagoon is a body of water located on the southeastern coast of Union Island in Saint Vincent and the Grenadines.

This sheltered bay is characterized by its shallow, clear waters and surrounding mangrove ecosystems.

Visual Characteristics

The lagoon's water exhibits a pale turquoise to light blue hue, varying with depth and sunlight penetration. The seabed is primarily composed of fine sand and seagrass beds. The perimeter is defined by dense mangrove forests, primarily red mangroves (Rhizophora mangle), with their characteristic prop roots extending into the water. The lagoon is relatively shallow, with depths generally not exceeding 2 meters in the main channels.

Location & Access Logistics

Ashton Lagoon is situated on the southeastern side of Union Island. Access is primarily via the main road that encircles the island. From the capital, Clifton, travel east along the coastal road for approximately 3 kilometers. Parking is available at designated informal pull-offs along the road adjacent to the lagoon. Public transport on Union Island consists of minibuses; the route serving this area can be identified by asking drivers for the Ashton Lagoon or Clifton to Ashton direction. Boat access is also possible for those with private vessels, with mooring options limited and requiring careful navigation due to shallow areas.

Historical & Ecological Origin

Ashton Lagoon is a natural geological formation, classified as a coastal lagoon. Its formation is attributed to the accumulation of sediment and the growth of coral reefs offshore, which created a sheltered embayment. The surrounding mangrove forests are a vital ecological component, acting as nurseries for marine life and providing coastal protection. Historically, the lagoon and its surrounding areas have been utilized by local communities for fishing and resource gathering.

Key Highlights & Activities

Kayaking and paddleboarding are suitable activities within the lagoon due to its calm waters. Birdwatching is possible, with various coastal and mangrove-dwelling species present. Snorkeling can be undertaken in specific areas where the water is clearer and marine life is more concentrated, typically closer to the reef edge. Limited fishing is permitted in designated zones.

Infrastructure & Amenities

There are no formal facilities directly at Ashton Lagoon. Restrooms are not available. Shade is provided by the natural canopy of the mangrove trees. Cell phone signal (4G/5G) is generally available in the vicinity. Food vendors are not present at the lagoon itself; provisions should be made from Clifton or other settlements.

Best Time to Visit

The best time of day for photography is generally mid-morning to early afternoon when sunlight is most direct, illuminating the water colors. The dry season, from January to May, offers the most favorable weather conditions with lower rainfall. High tide is recommended for easier navigation by kayak or paddleboard and for accessing areas with slightly greater depth.

Facts & Legends

Local folklore suggests that the lagoon was once a favored resting place for sea turtles during their migratory journeys, though this is not scientifically verified. A practical tip for visitors is to be aware of the shallow sandbars that can emerge at low tide, requiring careful navigation for watercraft.
