Colorado Elk Mule Deer Pronghorn Bear

Unit 75 (Vallecito)

Colorado Hunting Guide — Elk, Mule Deer, Pronghorn, Bear

Unit 75 sits in the southwest corner of Colorado, against the New Mexico line, in La Plata and San Juan Counties. It covers about 646 square miles of steep San Juan Mountains country, from low ground along the Animas and Los Pinos drainages up past 13,000 feet in the Needle Mountains. CPW publishes no per-unit elk breakdown here. What decides this hunt is access: big country, few roads, and a lot of vertical.

Elk Hunting in Unit 75

Unit 75 sits in the southwest corner of Colorado, against the New Mexico line, in La Plata and San Juan Counties. It covers about 646 square miles of steep San Juan Mountains country, from low ground along the Animas and Los Pinos drainages up past 13,000 feet in the Needle Mountains. CPW publishes no per-unit elk breakdown here. What decides this hunt is access: big country, few roads, and a lot of vertical.

Where to Find Elk in Unit 75: High Basins, Lower Shoulders and the Boundary Roads

CPW's unit material for 75 gives a boundary description and nothing more. It has no narrative on where the elk winter, calve or rut. We won't pretend otherwise. What follows comes from the boundary, the terrain and the elevations, so treat it as a map read and not a promise of animals.

The frame: Animas River to the Continental Divide

The unit is bounded on the west by the Animas River and on the south by New Mexico. Its northern and eastern edge follows a county line, the Continental Divide, and the Los Pinos River–Florida River divide. It then drops along La Plata CR 240 (the Pine River–Florida River Road), the Bayfield–Vallecito Road and the Los Pinos River. That's roughly 646 square miles in herd unit E-31. The rivers and roads on that line are how you get in. They aren't where we'd start looking for elk.

Needle Mountains and Grenadier Range: the high country

The interior is the highest ground in the unit. Windom Peak (13,979 ft), Sunlight Peak (13,965), Pigeon Peak (13,912), Vestal Peak (13,815) and Jones Mountain (13,812) all sit on public land, and the Needle Mountains top out at 14,008. Those summits are glassing landmarks, not places to hunt. Elk use the basins and benches below them, and the early-season ones are the ones to study on a topo. The gentler ground comes lower: Hazelton Mountain (12,476 ft), Peak Fourteen (12,550) and Lime Mesa (12,101). Overlook Point (12,993) is a cliff, so use it as a vantage and don't count on it for feed.

Lime Mesa and the lower shoulders

Lime Mesa is the one named landform in the unit that reads like a mesa. It's flatter and lower than the peaks around it, and it's in La Plata County on public ground. If you want to test a bench-and-timber pattern before committing to a long pack-in, start there. Later in the season, expect animals to slide down toward the unit's low edge, which runs from about 6,500 feet. We'd study the drainages feeding the Los Pinos and Animas for that move.

What to skip

  • Anything above roughly 13,000 feet. It's rock and snow, and nobody's going to find a herd there when the weather turns.
  • Ground right along the Bayfield–Vallecito Road and the lower Los Pinos. Check ownership before you plan around it, because unit-edge corridors tend to be mixed.
  • Long walks on a guess. With no agency map of where the elk are, scout first.

Unit 75 terrain and land status

Named features inside the unit

Glass from: Mount Eolus (14,016 ft), Windom Peak (13,979 ft), Vestal Peak (13,815 ft), Jones Mountain (13,812 ft)

Holding ground: Trimble Pass (12,877 ft), Cinnamon Pass (12,630 ft), Stony Pass (12,593 ft), Bayfield Lions Club Shooting Range SWA, Pastorius Reservoir 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

All manners of take14%
Archery10%
Muzzleloader9%
Rifle15%

CPW's 2023 harvest estimates put elk success in unit 75 at 14% — 207 animals taken by 1,469 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, 29 taken by 280 hunters
  • Muzzleloader — 9% success, 7 taken by 78 hunters
  • Rifle — 15% success, 172 taken by 1,111 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.

CPW's 2026 draw recap for elk in unit 75, by hunt code, with resident and nonresident kept apart because the two draw from different licence pools:

  • EM075O1A — Archery, 1st Season, Bull Only, nonresident: 628 applicants for 185 licences, 29.5% drawn, no preference points needed
  • EM075O1R — Rifle, 1st Season, Bull Only, resident: 430 applicants for 162 licences, 37.7% drawn, no preference points needed
  • EM075O1R — Rifle, 1st Season, Bull Only, nonresident: 390 applicants for 135 licences, 34.6% drawn, no preference points needed
  • EM075O1A — Archery, 1st Season, Bull Only, resident: 386 applicants for 143 licences, 37% drawn, no 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 22 further code-and-residency combinations in the recap for this unit. Figures checked against CPW's own statistics pages on 2026-06-09.
