The 14-mile Frying Pan River proves size isn't everything. Anglers can easily pull 25 trout per day on dry flies from this sandstone canyon just 20 miles north of Aspen. Bring a five-weight rod, then pick up flies and 6X leaders from the Taylor Creek Fly Shop. Hit the public-access areas at miles 8 and 12. Book one night in Basalt at the Aspenalt Lodge, then splurge on a summer-discounted price at Aspen's Hotel Lenado. At night, fill 'er up at the Woody Creek Tavern, where Hunter S. Thompson used to hold court.
