Rio GrandeTalley to Solis
Remote Mariscal Canyon route through the shortest Big Bend Rio Grande canyon, from Talley to Solis. NPS names the public access plan, 10-mile route, Class II-III character, permit requirements, and high-clearance road constraints, while American Whitewater ties the run to the Rio Grande Village USGS gauge.

Permits, camping and season
Access and shuttle
Launch at Talley and finish at Solis for the remote Mariscal Canyon run. Use the Rio Grande Village USGS gauge with a conservative 200 cfs floor and NPS 300 cfs day-float cue, then make a same-day call on permits, River Road access, low-water dragging, Rock Pile, Tight Squeeze, heat, and storms.
Access map
Put-in
Talley River AccessAmerican Whitewater coordinates are access anchors, not guaranteed wetted-edge launch points. Follow NPS signs, current road and bank conditions, and ranger guidance on arrival.
Take-out
Solis River AccessNPS says high-clearance vehicles are usually required for both Mariscal access locations and the river road is rarely passable to passenger cars. Loose sand near the Talley road end is specifically called out.
Road shuttle
Stage Solis first and scout the take-out from the road so it is recognizable from the river, then drive the high-clearance River Road approach to Talley. NPS says Panther Junction-to-Talley can take two to two and a half hours and road conditions should be checked before final plans.
Additional access notes
- The route is currently below the 200 cfs conservative floor. Low water can mean dragging, longer exposure, harder lining choices, and more consequential boulder moves in the canyon.
- Solis is the common take-out, but NPS warns not to overshoot it because the next access is far downstream. Scout the take-out before launching.
- The route is border-adjacent and remote. Use only lawful U.S.-side access, respect international/private-land limits, and carry reliable emergency communication and enough treated water capacity.
More route and safety guidance
- American Whitewater identifies Rock Pile and Tight Squeeze as the named rapid features, with the route often treated as a multi-day trip because of the shuttle rather than mileage alone.
- NPS requires a backcountry river permit before launching, Type I/III/V PFDs in Mariscal, spare equipment, overnight waste/fire-pan systems when camping, and camps placed above the high-water mark and out of arroyos.

NotesPublished evidence and verification notes
These notes cover the access details, route quirks, and source caveats most likely to matter once you get there.
- Official route shapeTalley to Solis, about 10 mi
NPS identifies Mariscal Canyon as the shortest Big Bend canyon at 10 miles, with Talley as the put-in and Solis as the common take-out; American Whitewater lists the same reach at 10.2 miles.
- Public access coordinates28.98320, -103.18400 to 29.04430, -103.10600
American Whitewater publishes the put-in and take-out access anchors for Mariscal Canyon; NPS confirms Talley and Solis as the normal access locations and warns that high-clearance vehicles are usually required.
- Gauge check during route review · 2026-08-10USGS 08375300 at 30.4 cfs / 2.32 ft
This reading was saved when we checked the guide. It is not today’s water level. Check the current gauge and local conditions before paddling.
- Threshold posture200 cfs floor; 300-1000 cfs preferred open-boat window; 2000 cfs high-water caution
American Whitewater gives Mariscal a lowest recommended flow of 200 cfs; NPS says Mariscal can be floated in a day above 300 cfs and open boats should use caution above 1000 cfs. NPS river regulations add high-water equipment cautions at 2000 cfs for Mariscal and other canyon sections.
- Camping and permitsNPS backcountry permit required; overnight-capable with restricted zones
NPS requires a backcountry use permit before watercraft is placed on the Rio Grande in Big Bend and restricts camping near vehicle-accessible river-road sites unless separately permitted; overnight plans must use legal river camps above the high-water mark.
- SafetyRemote roads, Rock Pile, Tight Squeeze, heat, sudden rises
NPS warns about rough River Road access and remote logistics; American Whitewater identifies Rock Pile and Tight Squeeze as the main named Class II features, and NPS river regulations require self-sufficient safety gear and rapid scouting.
