Lime Kiln Point State Park, State park on San Juan Island, San Juan County, Washington, US

Lime Kiln Point State Park is a 42-acre Washington state park on the western shore of San Juan Island. It holds one of Friday Harbor's two lighthouses, a stone lookout with picnic tables, and a restored 1860 lime kiln. Trails lead along rocky shores where visitors watch orcas from land.

Starting in 1860, this site operated as a lime production facility where limestone was burned for building materials. One of the original kilns survives today and stands as evidence of the area's industrial past.

The park's name comes from the lime kilns that operated here from 1860, and one restored kiln is displayed for visitors. Volunteers and marine naturalists are often on site to help visitors spot orcas and explain the former lime-burning industry.

The park is accessible by road and has parking near the entrance, with trails along the shore suitable for walking. A valid Washington state park pass is needed to enter, and visits are most rewarding during the warmer months when marine activity increases.

The underwater shape of the seafloor near the shore allows whales to come very close to land, sometimes within just a few meters of the beach. This geography makes the park one of the best spots on the west coast to watch these animals from solid ground without needing a boat.
