Anniversary trip recommendations in early March

My 10 year wedding anniversary is next year, first weekend of March. Looking for recommendations for a 4 night getaway for just the wife and me. Not really wanting to go to a beach, we are more into national parks, hiking, scenic views, etc. Would like to go somewhere we haven’t been before. Been to Yosemite, Zion, Bryce Canyon, Lake Tahoe, New England area. Kinda concerned that places like Colorado or Yellowstone would be hard to navigate due to winter conditions. Any recommendations for an early March trip would be appreciated.
