During the Summer months the 3 Sisters Lighthouses in Eastham have tours. On Sundays and Tuesdays you can learn some interesting facts and history about these lighthouses. At 5pm and for 1 hour you can tour the lighthouses and stroll through the Eastham trails learning about the importance of a lighthouse. The start of the tour is at the Nauset beach parking lot just 1/4 mile from the lighthouses. You will then have a guided walking tour to the lighthouses as well as a chance to see the inside of them. This is a great activity to do with the family at the end of a long day at the beach.
