Colorado Summer Birding Tour

7 Days

Colorado in Summer is a very pleasant place to go birding, and can be quite productive. The high mountain passes become drivable again without any snow, so certain difficult birds like White-tailed Ptarmigan and Brown-capped Rosy-Finch become more attainable. The scenery and weather is all quite nice, and can provide a relaxing escape for folks in the hotter parts of the country.

More details about this trip:

Birding is of course the primary purpose of this trip, and it is designed to pass through a large variety of habitats to see the maximum number of birds. The trip will include the eastern grasslands for longspurs, sparrows, and hawks, the Rocky Mountains for montane forest birds and high tundra specialties, and the western slope for owling, western birds, and the endemic Gunnison Sage-grouse.

Pricing: $1,990 USD, or £1,460 for 7 Days and 6 Nights


Group Size: Price is based on a group size of 8 participants.
