On this ride, you'll cruise along the coast before beginning your climb through Moran State Park and eventually conquering Mt. Constitution. Passing by quiet inland lakes, you'll make your way through moss-covered forests, before ascending a series of switchbacks. All the while, leading you past some breathtaking viewpoints on your way to Mt. Constitution tower. Be prepared for an approximately 6-mile ascent with numerous switchbacks and steep grade but keep in mind the ride down will be a fun one. 

Author’s recommendation

Although a challenge, the views from the top of Mt. Constitution are every bit worth the effort. On a clear day, you'll be able to spot the other San Juan Islands, Canada, and the magnificent Cascades Mountain Range. There are also some great short hike options in Moran State Park, making for an all-around excellent day.

Safety information

You'll be traveling on paved main roads for the entirety of this ride but use caution as most roads have minimal shoulders. Motorists are generally very courteous to cyclists but use caution at all times. Use extra caution during the switchback section, both during the ascent and descent. Maintain slow speeds on the way day and use bike pullout lanes when necessary. 

Before starting your ride it’s always worth inspecting your bike for any damage. Check for any damage to the frame, components or wheels. Ensure there are no loose cables and that the tires are inflated and the brakes are working. Always wear a helmet when biking. If you are doubtful of the condition of your rental bike please call the office or the local bike shop on the number provided in your information pack. We also recommend keeping your bike light on and set to flash, even during daylight and stay away from posted private property areas. 

Equipment

Always be prepared to bike through a change of weather conditions and do check for any local weather warnings before cycling. Good shoes, a windbreaker-type layer, sunscreen, and sunglasses are ideal items for a sunny day. If you happen to have rainy weather, waterproof pants and a jacket are a must. 

Most cyclists wear [fingerless] bike gloves for some padding on the handlebars. Don't forget a spare battery pack for an emergency charge of any navigation unit you may decide to use. Don't forget your camera and even a pair of binoculars if you plan on spending a little time whale watching.
