If you can bring your bike, Crater Lake offers some challenging cycling. The Rim Drive is 33 miles long with many hills to tackle not to mention having to deal with heavy traffic during the summer. At least they are likely to not be going too too fast. Even during the winter one can ride from the Rim Village down to the Steel Visitor's Center and beyond to the Annie Springs entrance. Round trip is 14 miles. However there is the matter of the 3.3 miles from the Steel Visitor's Center back up to the Rim Village which has an average gradient of 3.7% with some steeper pitches near the bottom. Definitely a challenge from a low-lander from Richmond, VA!
Equipment: Bike, bike gear (don't forget the helmet!)
