Swim through the towering kelp stalks. Pay attention to the light filtering through the canopy, as it often indicates open pathways. You'll encounter new species of fish here, some of which you can ride by interacting with them. Riding larger fish can help you move faster and experience the environment from a different perspective.
Look for glowing cracks or openings in the kelp walls, as these often lead to hidden areas with meditation statues or fish pools. The kelp can be disorienting, so use your camera to get a good sense of direction.
