Experts have their hands full in Blackcomb's Alpine with Couloir Extreme, Secret Chute, Pakalolo and the four big, steep bowls accessed over Spanky's Ladder. Blackcomb's world-renowned 25-acre Nintendo Terrain Park is a scene worth checking out, even if you don't try it. Kids love exploring Arthur's Castle.
On Whistler, try peak-to-valley corduroy on Franz's in the morning. The zone between the Roundhouse and Olympic Station has oodles of offerings for beginners and intermediates who like to cruise. Whistler's six high alpine bowls have inexhaustible offerings for experienced skiers. West Bowl is always a good bet for powder. Symphony Bowl is readily manageable by confident intermediates.
On both mountains, if you think the conditions are crummy where you're skiing, try somewhere else altogether-you may find the conditions are brilliant. One word of warning: Never go over anything off-piste at Whistler or Blackcomb blind. It might look like a tiny roll, but it could easily be a cliff or a hole.
