Part of the San Juan Islands, Yellow Island is known for its wildflower-covered landscape. More than 50 species—including the only cactus native to western Washington—can be found here. Check the trees for bald eagles, listen for songbirds, and watch playful otters swim.
How to get there: Take a private boat from San Juan Island's Friday Harbor or Fisherman's Bay on Lopez Island; you can also kayak from Deer Harbor on Orcas Island. For more info visit nature.org.
Be sure to: Scan the shore for black oystercatcher birds prying open mollusks with their vibrant orange-red bills.
