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 is one of my favourite places to ride. This route may be short, but the last 25 km will more than make up for the lack of distance. The route starts out following the winding road out of Terra Cotta and soon ascends out of the valley with a good early test of the legs. The climb is short, but steep enough where some may need to get out of the saddle to reach the top. From here on through, with the exception of a short climb after Mississauga Rd., it is fairly flat for the next 25 km's. You will find King St. fairly busy east of Mississauga Rd. but the traffic is soon left behind with a right hand turn down Chinguacousy Line and eventually to a left hand turn onto Old School Rd. It's easy country riding and a good, solid warm up for the hills to come.

The hill section starts at the base of Caledon Mountain on Mountainview Rd. You don't climb all the way to the top on this route, but rather turn left onto the Grange Side Rd. Although you don't fully ascend Caledon Mountain you will keep climbing after your left hand turn all the way to St. Andrews Rd. Once you cross St. Andrews Rd. you will mostly be on a downhill run with a few rollers in between all th way to Hwy 10. For those of you who would like to do a small side trip, turn left on St. Andrews Rd. and descend the mountain. The pavement is good as are the sightlines. You will top 70 kmph on this descent. Once at the bottom turn around at Old Base Line and return the way you came. It's a good climb. If you want to go all the way to the top keep going past the Grange Side Rd. all the way to the top at Charleston Side Rd. Once there, turn around, descend and get back on route at the Grange Side Rd. The Grange is a great road. It's what you think country riding should be. You will stay on this road until your left hand turn onto McLaughlin Rd. The views here are fantastic. You are right up to the slopes of the escarpment surrounded by farms and woodland pastures.

Your turn onto McLaughlin Rd. will lead you straight towards a climb coming into the village of Inglewood. You will find food and water here. Inglewood sits in a small valley bordered to the north and south by two hills. You will climb them both. Both are fairly short and will top out near 10%. Your next series of climbs will on Boston Mills Rd. where you will climb half way up the mountain and plunge back down again into the Village of Cheltenham. You will find food and water here as well. No sooner than you descend into this quaint village you will see a large hill straight ahead of you. This is your way out. So basically, you will climb four good hills after your turn onto McLaughlin Rd. This should not present too much trouble if you are following the route as laid out. At 49 km's the route is fairly short, with a 25 km flat section followed by some hills sets in some of the best scenery Southern Ontario has to offer.
