Unit 33 (Glenwood Springs)
Colorado Hunting Guide — Elk, Mule Deer, Moose
Unit 33 sits in Garfield and Rio Blanco counties on the western slope, framed by Colo. 13 on the west, Canyon Creek on the east and the Colorado River on the south. It runs about 416 square miles, from river bottom near 5,700 feet to ridges above 10,000. CPW publishes no per-unit elk breakdown, so we're working from terrain and access. Confirm public-land boundaries on a current map before you commit.
Build your own PDF hunt guide for Unit 33
Answer a few questions about your tag, your season and your rig, and the Field Intelligence Report builds a print-ready Colorado Unit 33 guide around your hunt: three ranked spots with morning, afternoon and evening plays, a day-by-day plan, topo maps with every pin numbered, a camp and access plan, the legal and retrieval rules for this unit, shot discipline, a meat-care and pack-out plan, and a pre-trip checklist. Every coordinate sits on land recorded as public.
Free accounts get one report a year with the top spot unlocked. ProHunt Pro includes unlimited reports, all three spots, the full camp plan, and GPX/KML downloads for onX and Google Earth. Prefer to see one first? Open the builder and pick any unit.
Elk Hunting in Unit 33
Unit 33 sits in Garfield and Rio Blanco counties on the western slope, framed by Colo. 13 on the west, Canyon Creek on the east and the Colorado River on the south. It runs about 416 square miles, from river bottom near 5,700 feet to ridges above 10,000. CPW publishes no per-unit elk breakdown, so we're working from terrain and access. Confirm public-land boundaries on a current map before you commit.
Elk Country Between Colo. 13, Canyon Creek and the Colorado River
CPW's own unit material gives this unit a boundary and nothing more. It's bounded on the north by the White River–Colorado River divide, on the east by Canyon Creek, on the south by the Colorado River and on the west by Colo. 13. It lists Garfield and Rio Blanco counties and puts the unit at about 416 square miles, in elk herd area E-6. There's no narrative about where the elk are. Those boundary features frame the unit and tell you where the roads come in. They don't tell you where elk stand, and we won't pretend they do.
Read the ownership before you plan
Our ownership read for this unit came back as all private or other, with no public share we'd trust. Yet the named summits, parks and gulches inside it carry public-land flags. Those two things don't agree. Pull a current land-status map and trace public ground yourself before you pick a camp. Nobody's told us how much of the unit is open to you, and you don't want to find out on opening morning.
Parks and benches: Triangle, Seaman and Lake
For holding country, start with the high flats. Triangle Park (9,466 ft), Seaman Park (9,298) and Lake Park (9,260) are the strongest-looking bench country on our terrain read. They sit on the same upper shelf as Coulter Mesa (9,289) and Clark Ridge (9,743). Open ground backed by timber is where we'd look first early in the season. Long Park (8,278) is the lower version of the same idea, and it's the step down when snow or pressure pushes animals off the top.
The gulches: Tangle, Irish, Hoover and Trappers
Below the parks, a run of gulches drops toward the river: Tangle Gulch (8,565), Irish Gulch (8,498), Hoover Gulch (8,427), Trappers Gulch (8,189), Garden Gulch (7,844), Bear Gulch (7,807) and Stump Gulch (7,720). These are the late-season and weather-push candidates. Elk drift down toward the lower, warmer ground once the high parks get cold. Skip the river-bottom end of the unit, near 5,700 feet. The mean elevation is about 7,800, and the useful country sits well above the bottom.
Getting there
Colo. 13 is paved and runs 7.3 miles along the west line. CO 325 is paved for another 4.3. CR 252 is graded gravel for about 10 miles and fine for a 2WD rig with a small trailer. The real backcountry roads are high-clearance: FR 601.1 (11.2 miles), FR 245.1 (7.3) and FR 211.1 (5.7). Silt, New Castle, Rifle and Glenwood Springs are the nearest towns for fuel and supplies.
Two high points, Spring Hill and Clinetop Mesa, top our list of glassing summits. They sit at or past the unit's high edge, so check the line before you plan around them.
Unit 33 terrain and land status
Measured from the unit boundary, not from the agency write-up
The lay of it
- 5,714–10,626 ft on a terrain sample , averaging 7,792 ft ; peaks can run higher. That spread means you can hunt two seasons in one day — plan clothing for both ends.
- 415.6 sq mi inside the boundary.
Who owns the ground
- National Forest — 60%
- BLM — 15%
- State Trust — 8%
- Private / Other — 17%
Roughly 83% is public. Carry a land-status layer anyway — these are area percentages, not a map of where the boundaries fall.
Water on the ground
- 493 tanks
- 8,554 stream segments
- 12 lakes
Counts from mapping data, so this is how many exist, not how many hold water in a dry year. Sitting water only pays where you find fresh tracks.
Named features inside the unit
Glass from: Spring Hill (11,113 ft), Clinetop Mesa (10,670 ft), Clark Ridge (9,743 ft), Coulter Mesa (9,289 ft)
Holding ground: Triangle Park (9,466 ft), Lake Park (9,260 ft), Tangle Gulch (8,565 ft), West Rifle Creek SWA, Wheeler SWA
Every one of these was tested against the unit polygon before it went on the map. They are starting points, not agency recommendations.

Elk Success Rates
CPW's 2023 harvest estimates put elk success in unit 33 at 11% — 249 animals taken by 2,351 hunters. That is a lot of hunters in one unit, and the percentage is what it looks like after all of them have been through it.
- Archery — 10% success, 42 taken by 438 hunters
- Muzzleloader — 16% success, 14 taken by 90 hunters
- Rifle — 11% success, 193 taken by 1,823 hunters
These are the agency's own printed figures for this unit, not a modelled estimate and not a state average. They describe one season, so check CPW's current harvest estimates before you read a trend into them.

Open in Draw Odds EngineCPW's 2026 draw recap for elk in unit 33, by hunt code, with resident and nonresident kept apart because the two draw from different licence pools:
- EE033O1A — Archery, 1st Season, Either Sex, nonresident: 994 applicants for 160 licences, 16.1% drawn, 3 preference points needed
- EE033O1A — Archery, 1st Season, Either Sex, resident: 784 applicants for 451 licences, 57.5% drawn, no preference points needed
- EE033O1M — Muzzleloader, 1st Season, Either Sex, resident: 251 applicants for 65 licences, 25.9% drawn, no preference points needed
- EE033O1M — Muzzleloader, 1st Season, Either Sex, nonresident: 162 applicants for 25 licences, 15.4% drawn, 6 preference points needed
Colorado runs a pure preference-point draw, so the point figure above is the requirement the agency published for that code in that year, not a forecast for the next one. There are 14 further code-and-residency combinations in the recap for this unit. Figures checked against CPW's own statistics pages on 2026-06-09.
