getting there

Drive US 101 to 12 miles southeast of Sequim and turn left on Diamond Point Road. Continue 2 miles and turn left into the large parking area.


  • Thompson Spit and its remarkable lagoon lie 0.75 mile east of where the trail reaches the shoreline and may not be reachable if the tide is too high.
  • The beach walk traverses slippery cobblestones, so sturdy footwear is recommended.
