When Is the Snow Gone from Trails in Rocky Mountain National Park?

One of the most common questions we get from spring and early summer hikers is: “When do the trails open?”. Technically, the trails in Rocky Mountain National Park are open year-round—but snow conditions play a huge role in whether they're comfortably hikeable. While some lower-elevation routes melt out by mid-spring, many popular trails at higher elevations stay snow-covered well into summer.

Here’s a general guide to when trails become snow-free:

• Lower elevations (below 8,500 ft):
  Trails like Lily Lake, Moraine Park, and Cub Lake often melt out by late March through April.

• Mid elevations (8,500–10,500 ft):
  Trails such as Bear Lake, The Pool, or Bierstadt Lake may be clear by late May into June, but watch for lingering drifts and mud.

• High elevations (above 10,500 ft):
  Think Sky Pond, Flattop Mountain, and Chasm Lake. These are typically snow-covered until late June or July, and may require snow travel gear well into summer.

A few quick tips for hiking during snowmelt season:

• Always check trail conditions on the official RMNP trail page before heading out.

• Bring microspikes or traction gear for icy mornings.

• Start early—melting snow creates slushy, muddy trail conditions in the afternoon.

• Don’t assume “summer gear” applies yet—spring hiking can still feel like winter above tree line.

Every year is a little different depending on snowfall, wind patterns, and sun exposure. If you’re unsure whether your favorite trail is ready, reach out—we’re always happy to share recent conditions from our guided trips.
