May 27, 2026, River Bend Road

Gorgeous remote road and best access route to Riverbend Regional Park that does not pass through Great Falls NP. Be aware, in May 2026 there is resurfacing underway so half the road is rough-surfaced and uneven. Slow speed and caution recommended.

There isn't a ton of traffic on this mostly straightaway road, but there also isn't a shoulder to bike on — so stay alert for vehicles.
