Flow / best time to visit (official)

Reached via Old Fall River Road, a one-way unpaved road normally open only from roughly early July through early October depending on snowpack; closed to vehicles the rest of the year (per NPS road-status announcements).

Our take

Chasm Falls is a roadside waterfall in Rocky Mountain National Park, accessible via the Old Fall River Road—a one-way unpaved scenic road that operates only July through early October depending on snowpack. Visitors can park at pullouts and view the falls from short walks.

The exact height and standard round-trip distance are not documented by NPS, but the falls are easily visible from the road. An entrance fee is required; verify current road status before planning a visit, as opening dates shift with winter conditions.

Best visited July through September when Old Fall River Road is reliably open and alpine conditions are most stable.

NPS Old Fall River Road page and 2026 NPS news releases confirm the road (and roadside access to Chasm Falls) was open for the 2026 season as of this check. Round-trip distance varies with where visitors park (as little as ~0.2 mi from the closest pullout) and isn't standardized by NPS, so left null; height also not documented by NPS. Checked Sept 2026.
