Access map
Put-in
Grizzly Creek Boat Ramp / I-70 Exit 121Use the documented Grizzly Creek Boat Ramp at I-70 Exit 121 and the City of Glenwood Springs Two Rivers concrete ramp only. The Grizzly Creek ramp is reached by stairs/boat-launch access; do not unload from a travel lane or substitute an unmarked bank.
Take-out
Two Rivers Park Colorado River boat rampGlenwood Canyon access can close for fire, debris-flow, construction, rockfall, traffic, or weather conditions. Check current CDOT/Forest Service notices and do not launch during a closure.

Access notes and hazards
Access caveats
- Use the documented Grizzly Creek Boat Ramp at I-70 Exit 121 and the City of Glenwood Springs Two Rivers concrete ramp only. The Grizzly Creek ramp is reached by stairs/boat-launch access; do not unload from a travel lane or substitute an unmarked bank.
- Glenwood Canyon access can close for fire, debris-flow, construction, rockfall, traffic, or weather conditions. Check current CDOT/Forest Service notices and do not launch during a closure.
- Two Rivers is a high-use city facility: follow current hours, ramp-parking limits, commercial-permit rules, and no-overnight-camping/parking restrictions. Stage the shuttle lawfully before entering the canyon.
- The 900–8,600 cfs band is planning guidance only. Keep the route unavailable when discharge is outside the band, rapidly changing, unavailable, or inconsistent with the canyon visual; stop at Two Rivers before the separate South Canyon reach.
Watch for
- USGS 09070500 below 900 cfs, above 8,600 cfs, rapidly rising, unavailable, or inconsistent with the local visual check
- Class II/III current, commercial rafts, cold water, strainers/sweepers, bridge and canyon hazards, debris, and limited recovery options
- CDOT/Forest Service/city closures, I-70 traffic, ramp parking and permit rules, and failure to exit at Two Rivers before the separate downstream route

NotesWhat to know before you go
These notes cover the access details, route quirks, and source caveats most likely to matter once you get there.
- Named public corridorGrizzly Creek to Two Rivers Park; approximately 5.9 miles; Class II+(III)
American Whitewater names the corridor, difficulty, length, direct 09070500 gauge association, and standard public endpoints. RiverBrain independently names the same run and current access context.
- Direct live gauge and flow gateUSGS 09070500; 900 cfs minimum and 8,600 cfs maximum planning bounds; 1,250–5,500 cfs preferred planning band
USGS provides continuous discharge and gage-height telemetry. American Whitewater publishes the 900–8,600 cfs reach correlation; Colorado whitewater flow evidence identifies lower, standard, and high preferred bands. These are conservative planning cues, not a runnable guarantee.
- Lawful endpoint accessCDOT/Forest Service Grizzly Creek Boat Ramp to City of Glenwood Springs Two Rivers Park ramp
Glenwood Springs documents both Grizzly Creek and Two Rivers as area boat ramps, while CDOT identifies the Grizzly Creek launch adjacent to the rest area. Use the exact named ramps and verify current closures and parking.
- Safety boundaryExperienced moving-water users; mandatory Two Rivers exit before South Canyon
American Whitewater rates the reach Class II+(III) and warns that higher water becomes pushier. Preserve commercial-traffic, cold-water, strainer/sweeper, debris, and canyon-closure warnings and do not continue into the separate Two Rivers-to-South-Canyon package.
- Camping and shuttle logisticsNo endpoint camping; separate lodging/campground required; I-70 shuttle
The named endpoints are a rest-area/boat-launch context and a city day-use ramp. No on-route camping is implied; stage a legal vehicle shuttle and use separate lawful lodging or camping.
- Duplicate separationDistinct Grizzly Creek-to-Two Rivers corridor above the existing Two Rivers-to-South-Canyon route
This route ends at Two Rivers and uses direct 09070500. The existing lower route begins at the same city endpoint but uses 09085100 and continues downstream to South Canyon; the shared boundary endpoint does not make the reaches duplicates.
