Confederation Trail, just outside of Charlottetown, PEI.
One of the reasons we chose to vacation in Prince Edward Island was because of the amazing road biking. Now that we literally have a kid-in-tow when out for a family ride, we aren't too keen on taking her into traffic, especially with the overly aggressive and often distracted drivers here in Boston. So when Lee found out that this province has a road bike-able trail that passes right through Charlottetown, we were excited to try it out.
The Confederation Trail, which was once the province's railroad system, spans the entirety of Prince Edward Island. There isn't a lot of elevation change or challenging terrain, making this the perfect ride for towing a baby trailer or riding with kids. And with so many quaint towns and little bed-&-breakfasts along the 273-kilometer trail, you could really make a wonderful vacation of riding across the entire island.
Would you do a biking vacation? Absolutely. In fact, we've talked about going back to PEI to ride the entirety of the trail maybe even as early as this fall.
