General Guidelines

  • Tides in the St Croix River range up to 24 feet. Use caution while walking in the intertidal zone — that is, the area between high and low tide. Seaweed and algae-covered rocks are very slippery!
  • Check for ticks. Wear long pants and use insect repellent.
  • When in doubt, ask a ranger first.


Ticks are prevalent in Maine. Mostly active late spring to early fall, these pesky biters can transmit Lyme disease and other illnesses. To protect yourself:

  • avoid brushy areas and dense leafy areas where ticks are abundant,
  • wear long pants and sleeves,
  • check your skin and clothes frequently for ticks,
  • use an appropriate insect repellent containing DEET,
  • shower soon after being outdoors.
For more information visit the Centers for Disease Control and Prevention's Ticks page.

Boating Safety

  • Four-wheel drive is required to launch trailered boats from the rudimentary boat launch. Plan ahead! It's best to launch and remove boats near high tide. From mid-May to mid-October, you can call the ranger station at (207) 454-3871 for tide times. A public commercial boat launch is located just 3 miles (5 km) south on ME-1 in the town of Robbinston.
  • Kayaks are best launched at high tide. Paddlers beware! Strong currents are common in the St Croix River due to the extreme tidal range.
  • Boaters are reminded that visits to Saint Croix Island are not recommended due to its fragile nature, both archeologically and geologically.
