A Gas station nowadays also acts as a rest stop and a convenience store, so during your 4 hour travel from seoul to Mount Sorak, I suggest you stop at a gas station to buy supplies for the long hike and walking that you will do when you enter the Sorak National park!
What to pay: depends on what you buy
Nature reserve or no, Sorak does have shopping opportunities at the bases as well as at the top.
Souvenirs are much better at the Sorak entrance (not Osek) and you can pick up beautiful wind chimes and all manner of trinkets and climbing accessories for sky-high prices.
At the top of the mountain, make sure you bring some cash with you for hot coffee, ramyeon noodles and, perhaps, a map of the area or a Buddhist bracelet.
