I did the paved part of the short loop, with a side trip to the beach along the Swan Cove Trail, and had a good time. The Wildlife Loop is open to vehicles from 3 PM to dusk, and it's pretty busy on the weekends, so you won't be lonely(!). The Swan Cove Trail has been realigned, so that it goes directly to/from the beach (0.5 miles) instead of parallelling it to Parking Lot 1 (1.3 miles); this will cut off about a mile from the total distance. If you overshoot on the beach leg and end up at Parking Lot 1, you can walk up Beach Road all the way back to the Visitor Center, or take it to the Black Duck Trail where you can cut across back to the Wildlife Loop. Bring your DEET, as the mosquitoes are vicious, particularly at dawn and dusk. For the driving directions to the trailhead: the highway bridge into Chincoteague City has been realigned, so you don't have to go left on Main, but just go straight on Maddox. There is a great takeout sandwich shop (Sea Star Cafe) in town, so you may want to turn right on Main and drive about 1/4 mile to grab a bite before hitting the trail.
