Route Schematic
Route & Key Stops
The typical itinerary moves from marsh entry into channel exploration and finishes with a river return to the sea; if tides or weather prevent marsh access, the session is run around the harbour and bay.
Marsh Entry
Enter the flooded marshland during the spring-tide window and set out into shallow channels.
Channel Exploration
Thread narrow channels, scout for wildlife, and work moving water under instructor guidance.
River Return or Harbour Alternative
Use the river to wash back out toward the sea; if wind, swell or tide prevent marsh access, the group will paddle in and around the harbour and bay instead.
Prior SUP experience is required; the operator will alter the route or run an alternative harbour/bay session when tides, wind, swell, or minimum-group requirements make the marshland inaccessible.
