Rocky Mountain National Park
Packing Checklist
Trailheads here start higher than most parks top out — 8,000 feet, 9,500 feet — and a three-mile hike often ends above tree line at 11,000. This impacts every gear decision you make. You'll get dehydrated faster than normal and the UV is stronger than normal. The 30-degree quilt that's perfect in July at most parks might not cut it for alpine nights. The rain shell that's optional in most parks is what keeps you alive when an afternoon storm finds you on tundra.
There is beautiful flowing water in the park. But you'll need to treat your water, even when it looks crystal clear. Be off the summits and out of the open tundra by noon from June through August; lightning in this park is dangerous, and you don't want to be caught out in it. Even outside of that window check the forecast and talk to a ranger before your trip. From April 1 through October 31 you need a hard-sided bear canister for any overnight. And don't only rely on your phone for navigation. You won't have service most of the time. A paper map and a compass are the backup that matters when batteries die or electronics get wet.

Trailheads here start at 8,000–9,500 feet. Climbs are sustained and you'll sweat more than the temperature suggests. I'd take ventilation over extra pockets every time.

Gregory Citro 30L
A pack designed with cooling and hydration built in.
Osprey Tempest 20 Womens Daypack
Versatile daypack with back panel ventilation and a 20L capacity. Fits smaller torso lengths.
Layer for a 40-degree morning and a 70-degree afternoon. Merino midweights handle that swing without smelling at the end of the trip.

InReach is the call here. Solo hikers especially benefit. Coverage drops the moment you leave the main corridors. Cold drains battery, so I keep electronics close to body in winter.
Power Bank

In-reach mini 3
Lightweight SOS satellite communicator uses the global Iridium satellite network so you can stay connected without cell coverage
Forerunner GPS Watch
Perfect if you love to track your hikes.
A first aid kit, a bivvy, and a whistle is the minimum I carry here. An afternoon storm above tree line can turn a two-hour hike into a five-hour problem.

SOL Emergency Bivvy
Heat-reflective emergency shelter that packs smaller than a soda can. Sub-4 oz insurance policy.
Fox 40 Emergency Whistle

Bars and a real meal-replacement work well at altitude when your appetite drops. Pack some fun tasty treats in case you don't feel hungry. I bring more calories than I think I'll want and usually finish them.
Clif Bar Variety Pack
Oat-based energy bars with 10-12g of protein each. Once you get tired of them try a different brand.

Sun protection and altitude come first. UV at 11,000 feet is no joke, even on overcast days, and snow reflection in winter doubles it. Reapply sunscreen more than you think you need to.
Nitecore Headlamp
Lightweight rechargeable headlamp.

Ventilated hat with maximum sun protection UPF 50+

Leukotape Blister Prevention
The blister tape thru-hikers swear by. Sticks through sweat and miles and prevents hot spots from becoming blisters.
Streams and lakes are everywhere, but every drop has to be treated, even when it looks crystal clear. Altitude pulls fluid out of you fast, I add electrolytes most days.

Premium taste-free, leak-proof reservoir with fast flow rate
SmartWater 1L Bottle

You don't need a sleep system for a dayhike, but an emergency blanket weighs almost nothing and matters when an afternoon storm pins you down above tree line.

Designed with insulation in mind, mylar emergency blanket can reflect over 90% of body heat, effectively preventing heat loss and ensuring your comfort and protection even in the harshest conditions.
Trekking poles take real load off your knees on a 3,000-foot climb, and that's a normal day here. Dry bags earn their weight every shoulder-season storm.
