Rent a quality mountain bike from Sockeye Cycle (5th Ave. near Broadway, 907/983-2851, www.cyclealaska.com ), which also offers a speedy ride down White Pass: Sockeye drives you up, and you roll back down on the bikes ($79). Another popular option includes a train ride up to Fraser followed by a downhill ride to town ($179). A 2.5-hour Dyea  bike tour is $79. Sourdough Car Rental (6th Ave. and Broadway, 907/983-2523, www.geocities.com/sourdoughcarrentals ) also rents bikes, including tandems.
A network of well-marked trails on the slopes just east of town makes for excellent day hikes and a place to warm up for the Chilkoot Trail . Cross the small footbridge and railroad tracks beyond the end of 3rd and 4th Avenues, then follow the pipeline up the hill. Lower Dewey Lake is a 20-minute climb that gains 500 feet in elevation. A trail right around the lake branches at the south end off to Sturgill’s Landing (3.5 miles) on Taiya Inlet.
Upper Dewey Lake and the Devil’s Punchbowl are a steep 2.5-mile climb from the north end of the lower lake. Icy Lake is a relatively level two miles from the lower lake, but the trail to Upper Reid Falls is steep and hard to follow. A number of clearings with picnic tables surround the lower lake, where camping is possible; others are at the other lakes and Sturgill’s Landing.
At 2nd Avenue and Alaska Street, go around the airport and take the footbridge over Skagway River. A short hike goes left to beautiful Yakutania Point, with views down Taiya Inlet. Go right and head steeply up to the Dyea Road; in one mile you’ll see the trailhead for A.B. Mountain, named for the Arctic Brotherhood—the letters AB are supposedly visible in snow patches each spring. This five-mile hike is steep and strenuous; the summit is 5,100 feet above your starting point at sea level.
The Forest Service maintains a refurbished rail car as the Denver Caboose Cabin ($35). This attractive old caboose is six miles north of Skagway  near where the railroad crosses the East Fork of the Skagway River. Access is by foot, or the White Pass & Yukon Route train  will drop you off for $30 round-trip. Take your binoculars to scan nearby slopes for mountain goats. The Denver Glacier Trail begins right beside the caboose and climbs five miles and 1,200 feet to Denver Glacier. It’s a beautiful hike through subalpine fir, paper birch, cottonwood, spruce, and other trees.
Another excellent hiking option begins at Glacier Station (14 miles north of Skagway). Have the White Pass & Yukon Route train drop you off ($63 round-trip), and then hike up the easy two-mile trail that leads to a Forest Service cabin ($35) near Laughton Glacier. Flag down the train to return. Make cabin reservations ($10 fee) for either the caboose or the cabin at 518/885-3639, 877/444-6777, or www.recreation.gov .
