Best Hikes/Hiking Tour Recommendations- Glacier and Yellowstone

Hi, I’m planning a camping trip to Glacier and Yellowstone and am curious if anyone has recommendations for hikes or hiking tours while we are out there. We hike pretty often near the DC area but may not be used to the conditions out there.

Also I’ve heard that it’s nice to have a guide when hiking for safety and you get to see the best sights, so we are interested in tours as well.

Having lived in the DC area, I assure you hiking conditions are far different in the Rockies. Not sure of your guides, but limit your hike times to mid July through August as weather conditions change really fast.
