You'll be able to pick up most of the achievements in the first 8 hours except for lesser and supreme snow god. After you've finished playing through the game most of the achievements will require you to impress the the required number of people per mountain and complete some easy miscellaneous goals.
Step 1: Finish the story mode, ending with the achievement "Big Musical Finale!" This shouldn't be too hard as most of the events aren't too difficult, try enough times on the events and you should prevail at some point.
Step 2: Go through each mountain and impress the required number of bystanders on each. Simply charge up your stoke meter and then do some sweet moves around un-impressed people. The impressed people is cumulative so it'll just take some time.
Step 3: Finish any challenge you haven't already and start trying to get gold on all of them. If you're having trouble on a challenge just come back to it later and hope you've improved since then. You can check your stats to see which events you still haven't finished.
Step 4: Get onto your snowmobile and start traveling until you unlock the achievement "Snowmobiler Merit Badge". Simply drop off at the top of the mountain, get onto your snowmobile and then go all the way to the bottom, rinse and repeat.
Step 5: Get onto your favoirte sled for crashing and take as much damage as you can until you unlock the achievement "Sledding Merit Badge". Again, spawn at the top and crash down to the bottom.
Step 6: Go into the editor mode and build as many cheap items as you can on each hill until you unlock the achievement "Park Designer Merit Badge".
