can anyone tell me about Olympic national Park?

Answer 1

In general, the trails and back country (with the exception of the coastal trails) are less crowded than the cascades. There are some fantastic camping opportunities. For outstanding views, I recommend Deer Park campground. If relaxation and short day hikes are more your thing, Sol Duc campground is a must with plenty of time spent in the hotsprings! The coastal areas, though busy in the summer, are breathtakingly beautiful.
