Lagoon Trail is considered difficult with long steep climbs, narrow trail, wet areas and glacial stream crossing. This challenge can take up to one and a half days. Access is at North End - Saddle Trail; South End - Halibut Cove Lagoon Ranger Station. It's a primitive route connecting the Grewingk and China Poot areas. From the Saddle Trail, the Lagoon Trail skirts above Halibut Cove, then drops to Halibut Creek Flats. There is no bridge at Halibut Creek. It is recommended that the stream be waded at low tide out on the tidal flats where the water will be shallower - otherwise expect swift, icy, knee to waist-deep water. Find the trail again by following orange trail markers around the tidal flats. A series of steep switchbacks then climbs into spruce forest to an intersection with Goat Rope Spur Trail, near timberline. The trail continues south, crossing a cascading creek and ends at the ranger station after steep switch backs. This is a rugged, difficult and exhausting trail and round-trips are not recommended. The trail continues on to lead you to China Poot Lake Trail, should you choose to go on.
