There is alot to do for both adults and children on Cape Cod. Families spend hours on the beaches. They seem to be more crowded earlier in the day with families and the later afternoons appear to be more popular with adults not accompanied by children. The public beaches prohibit alcohol but there are private beaches at the end of many streets where the people living/renting on the street go and bring coolers full of whatever they want. Some of the most beautiful beaches are located along the National Seashore in the outer Cape.
There are several breweries to tour and also a vineyard located in Truro if you enjoy wine. Museums, historical homes, playhouses, lighthouses, gardens, art galleries, whale watching, fishing, motorized and non-motorized water sports are just some things to keep you busy. There is even a drive in movie theater located on the outer cape. The Cape Cod baseball league hosts some of the best up and coming players.
There are walking and bike paths to enjoy. A few popular bike paths are the Cape Cod Canal path. You can enter at the Sandwich marina or Buzzards Bay Recreation Center. The path is located by the Sagamore bridge and runs along the canal heading up to the Bourne bridge. Another is the Cape Cod rail trail that runs from Dennisport to Wellfleet along an old railroad track. This trail is in the process of expanding toward Yarmouth. Race point beach has a bike path that runs through the sand dunes along the beach. The path isn’t very long but it is hilly and there isn’t much shade. The views are fantastic and there is a visitor center where you can park for free. Be sure to bring your own water and snacks.
If you have a chance to visit the Cape, the most cost effective thing to do is rent a home for the week. Beach parking is about $20-$25 per day. it is cheaper to buy a weekly pass or walk if possible. Most rental homes have grilles so you can bbq at home. Book early because many homes book in January for the upcoming season.
