March and April are two of the best months of the year to visit this sprawling fresh-water lake that straddles the border between California and Nevada. Spend your days kayaking in Emerald Bay, hiking trails through the mountains, or (if conditions permit) go shredding the nearby slopes. Accommodations range from rustic to luxe; check out the cabins on Airbnb or splurge on a spa holiday at The Landing Lake Tahoe Resort & Spa.
