Olympia is a very bicycle-friendly town, as far as American towns go. Very few roads have a speed limit over 25 or 30 mph, and many arterial roads have bike lanes.
Chehalis Trail: This amazing bicycle trail runs through Lacey and the east side of Olympia and spans 22 miles from Woodard Bay to the Yelm to Tenino trail near Rainier. The trails make for an outstanding collection of cycling pathways covering the far South Sound, typically available all year-round and with minimal interference from car traffic.
