Late April to early May is the start of Alaska cruising season

Advantages & Highlights:

• Fewer Crowds and Lower Prices: If you prefer a quieter, wallet-friendly adventure, late April to early May is ideal. Ports and popular tourist spots are less crowded, offering a more intimate experience with nature and local culture.

• Watch Wildlife Return: As the snow melts, moose, ravens, and resident forest birds become more active. You might also spot the first migratory birds and, occasionally, bears emerging from their winter dens. Bald eagles and gulls start appearing in towns, and ducks and geese can be seen in rare ice-free spots.

Be sure to pack a medium-weight insulated jacket, hat, gloves, layers and waterproof “break-up” boots.
