The last summer hike is this Saturday at 9am. It starts off cool, shady, and flat. Then it rises to this cool rock formation. You can opt to go the distance and make it to the rock, or turn around if you get hot or tired. If you've been to the beach this week, you know it's been socked in despite the heatwave, and since this hike is near the coast, it may be nice and cool.
