heading up next week looking for best route from the canal to Chatham. Is 6A any better than 28 or both just a busy? Also best route from Chatham to P-town? Thanks for the help

In general 6A is a better ride. Rt 28 sometimes seems to be a constant stretch of strip malls and parking lots with cars turning in and out all the time. Having said that, 6A is no picnic either - its narrow and twisty with lots of senior citizens driving along. If I was going to do it (and I have), I'd do it on a weekday and fairly early in the day.

I'd also look into using the Cape Cod Rail Trail as much as I could to get off the main roads. I'm not usually much of a MUP fan, but if it gets you where you're going, it might be better than battling with traffic. There are lots of organized rides that go from the bridges (both of them) to P'town - you might want to look at some of their route maps for ideas.

I concur with Baftap. 28 can be kind of ***** tonk. 6A is beautiful. There are also some beautiful quiet interior roads. The former rail right-of-way trail for bikes and peds goes all the way to P-Town as well.

I don't don't know the routes in enough detail to map it out. I once successfully used the google maps bike routing feature to map a Sagamore to New Seabury route. As you hone in on a route, maybe you could post a link to it here for added input.

Check out the Claire Saltonstall route. part goes along the RT 6 access road. Check out the rout from OUTRIDERS.org from boston to PTown. I used this route 3 years ago and turned it into a 6 day trip.
Get the Rubels bike maps for the cape also

Take 6A from the canal into Dennis, then pick up the CCRT and take the extension directly into Chatham. From Chatham to P Town, I'd suggest Route 28 into Orleans, then pick up the CCRT north into Wellfleet. From there it will be mostly back roads to Truro and Provincetown.

jealous cuz I love riding the cape. be aware that cape weather is different than mainland weather. btw the 2 mile bit of paved trail from N Truro to the S. End of P-Town is very bumpy due to roots pushing up and hasn't been paved in over a decade. it's a unique ride though and you get to see Pilgrim Spring (fresh water to wash your face with) up the stepped trail there you'll find wild blueberries during the summer months. Ocean view drive in Wellfleet is super sweet passing my favorite beach club: The Beachcomber and White Crest Beach where you can climb the dunes legally to get down and back up from the beach. There's another stretch of coastal road in Eastham connecting Coast Guard Beach and a lighthouse. Swim the ponds in Wellfleet and you'll never be the same. Great pond and Duck Pond in Particular. Great summer rides in a trisuit.
