The KVR trail from the Myra Canyon Trestles to Naramata is an incredible bike trip. Not difficult to ride at all (except for the sandy patches). This trail is not meant for road or hybrid bikes - bring your mountain bike - and lots of water!
The views are stunning and the restored trestles are amazing. Lots of great old train tunnels too! A great one day or two ride if you want to stay overnight in Naramata or Penticton.
The Myra Canyon from the East Parking Lot to the Parking Lot at June Springs Forest Service Road is about a 13KM ride or walk (non-motorized only). From June Springs FSR to Naramata, the ride is approx. 50 - 60km. We didn't know for sure. Motorized vehicles can access this section, so beware!
If you want to ride one way, you'll need a driver to drop you off, or use the shuttle service available from Penticton.
