Trail Ridge Road goes from Estes Park on the east side of the national park up and over the Continental Divide to the park’s west side and the town of Grand Lake. This is the highest continuous paved road in North America, peaking at 12,183 feet.
On this 48-mile scenic drive you’ll go through lush forest and the treeless alpine tundra where the Alpine Visitors Center (www.nps.gov , May 23–Oct. 8, weather permitting, daily 10:30 a.m.–4:30 p.m.) at 11,796 feet has small exhibits about plant and animal life from the area and rangers to answer your questions. The road is generally open from Memorial Day to mid-October, depending on snowfall.
There are dozens of lakes in the park where fishing is allowed, but you will need to check in at a visitors center  to find out which are currently open and fully stocked. For tours and lessons, contact Estes Angler (338 W. Riverside Dr., Estes Park, 970/586-2110, www.estesangler.com ).
