Zone 1 Map Zone 6 offers some of the most challenging routes this site has to offer due to both their length and elevation gain. This zone is bordered to the north by Hwy 89, to south by Hwy. 7, to the east by Hwy, 10 and to the west by Hwy. 6. Two of the most striking features of Zone 6 are Caledon Mountain and Hockley Valley. The terrain throughout this region is mostly rollers through forest and open pasture land. There are many conservation areas and small towns and villages to visit along the way.

There are two starting points in this zone. One is in the village of Terra Cotta and the other is in the Hamlet of Cheltenham. Terra Cotta is located in a small valley so a climb out will be required. It is not that difficult. Cheltenham starts on hill where a 10 minute climb will gain you summit. Some of the best riding is along Old Base Line and The Grange Side Rd.

The road quality in this area tends to be quite good. The best road up Caledon Mountain for surface quality is Heart Lake Rd. The prettiest road up Caledon Mountain has to be St. Andrews Rd. where you pass a golf course with a long, low stone wall that looks like it belongs somewhere in the Scottish country side. The long road through Hockley Valley is well surfaced, but it can be quite busy. There is a very wide shoulder so the traffic will not pose any issues.

Terra Cotta and the surrounding countryside are an absolutely a wonderful place to cycle. There is a good mix of flat roads to the south and climbs up Caledon Mountain to the north. This particular route starts in the village of Terra Cotta. There is a crude parking lot at the corner of King St. and Heritage Rd. You will see many cars with bike racks parked at this location. It's a great jumping off point for the surrounding countryside. Once you leave the parking lot you will turn right onto King St. which will curve it's way along leading to a small hill where you will climb out of the valley. From here on things will remain mostly flat for the next 20km, with one small exception as you pass over Mississauga Rd. You are now firmly in farm country.

The hills will start once you turn onto Heart Lake Rd. from Olde Base Line. From here it's about 10 km of hills leading up and over Caledon Mountain. The climbing is not stiff. The max gradient is 12%, but the majority of the climb is in the 6% range. There is one category 5 section, starting after The Grange Side Rd., which is where you'll find the steepest gradients. It's a nice climb. After your climb you will turn left onto Charleston Sideroad, which is anything but a "sideroad". This road can be busy with large transport trucks and a good amount of car traffic. You can get food and drink when you get to Caledon Village at Hwy. 10. You are on this road for only 4 km's, where you will then turn right onto Willoughby Rd. Now you are back in the country. After a short term cycling north you will turn back south into the little town of Alton. You can find food and water here, as well.

One of the tougher climbs on this route comes as you near the Forks of the Credit Rd. Once you see signs for the Caledon Ski Club a fast downhill section will veer to the left and the climb begins. It's not a categorized climb, but it's close. Most cyclists will be out of their saddle for portions of this climb. A short while later you will go through the tiny hamlet of Belfountain, where, once again, you can find food and drink. Don't take a wrong turn here. At the stop sign go straight. The route is fairly flat from here on through with the exception of one good hill out of Glen Williams. As a reward for this little nasty climb out of the "Glen" the downhill section of Winston Churchill, which comes shortly after, will have you reaching speeds of over 60kmph. The run-out is fairly long. You'll slow down before the sharp right hand turn you'll see ahead, not to worry.

I love cycling in this part of Southern Ontario. The roads are good quality, for the most part, it has farmland, forest and good sized hills. On most Saturday and Sunday mornings you will see large groups of cyclists taking advantage of the many route options this area has to offer. Look back frequently to this page as there will definitely be additional routes in the future. One will be a climbers day dream with the route going up the mountain no fewer than 6 times. Last time I did it, I tanked out and only went up 5. When you see the route posted you'll know that I eventually won.
