Tanguisson Beach

Tanguisson on Guam's northwestern coast is known for the limestone pillars standing in the shallows off the beach, eroded stacks left where the rest of the shelf has worn away, and for being the start of the walk north along the coast toward Lost Pond and the sea cliffs. A disused power station stands behind it. The sand is coarse and the water shallow over the reef flat. The coastal walk north from here leads to Lost Pond, a sinkhole in the limestone that holds fresh water a short way inland.

What you actually see

• The limestone pillars - eroded stacks standing in the shallow water.
• The coastal walk - the route north along the shore from the beach.
• The reef flat - the shallow shelf running out from the sand.
• The disused plant - the power station standing behind the beach.

When to go

December to June is the drier season. Tide governs how much reef flat is walkable. Weekends bring local visitors.

Honest expectations

The disused power station behind is an eyesore. The reef flat is sharp and shoes are needed. Currents at the reef edge are strong.
