Clark is about 16 miles north of Steamboat Springs on the road to Steamboat Lake. I got married very close to Clark (at Steamboat Lake) and we had our reception at Clark. It's right on the Elk River.
If you can afford it get yourself a tag. There are a few bigger bucks (I saw several camping there this summer) and you might get lucky and get a shot at one. Don't expect a Booner. More likely you'll be able to fill a tag on a smaller buck. You can expect to see lots of other hunters, the area has many forest roads, ATV trails, etc. Using your feet to get away from them is always a good idea. The tag is good over a huge area including units 4, 14, 214, and 441.
Best of Luck to you,
