Hiking over the Continental Divide via the Boulder Grand Pass is the most physically challenging and rewarding backpacking trip Wildland Trekking offers in Rocky Mountain National Park. This point to point trek starts near Estes Park and ends in Grand Lake, featuring a bit of everything. Dramatic waterfalls, isolated alpine lakes, plentiful wildlife, and significant off-trail hiking in seldom visited areas. Crossing the Continental Divide on day three will be the highpoint of the trip, literally. This is an excellent tour choice for individuals willing to put in the extra effort to escape the crowds.

On trips in June, snow is a slight possibility, and the rest of the summer rain is always a possibility on your trip. To be fully prepared, please follow the recommended clothing list closely (this list comes as part of your trip packet when you register). See below for average summer temperatures:
