Don't need an instrument approach to go to an airport IFR. To fly to 62S from DSD, track southeast on V165 on the DSD 143 radial until 70 DME. The routing would be filed as DSD V165 POCIT DSD143070 62S.
The MEA along the airway is 9500 feet, and the airport is 4317, so about 5200 feet above the ground. If the minimum vectoring altitude for the controller is lower than 9500 (unlikely), that would help you get lower. The point at which ATC is done with you on this route would be at the DSD 143 radial and 70 miles at 9500 feet. Then, you'd cancel, or ATC could climb you to their MVA, and you could continue to overhead the airport at maybe 11,000 feet (my guess at the MVA). Then, you'd have to cancel IFR, or sit there in holding, 'cuz that's your clearance limit. Might want to have a plan B or C then.
If there's real weather and you can't get in, then you'll have to shoot the approach at Sun River (S21), then "scud run" over to Xmas V. Not recommended at night, in real weather, or not familiar with the mountains and terrain. Good way to get dead, otherwise.
Good questions to go over with your instructor for IFR training.
