Rocky Mountain National Park covers 265,848 acres (415 sq mi) of Colorado's Front Range, climbing from 7,600ft to 14,259ft at the summit of Longs Peak, with 77 named peaks above 12,000ft. The busy east side is reached through Estes Park (about a 95-minute drive northwest of Denver); the quieter west side sits at Grand Lake. Four campgrounds take RVs, but Moraine Park is the headline rig: freshly rehabbed, it now offers 49 electric sites (20/30/50-amp) in Loops B and C, takes rigs to 40ft, has a dump station, and is the only campground open in winter. On top of a site reservation, day visitors need a 2026 timed-entry permit for the Bear Lake Road corridor (through Oct 19) or the rest of the park (through Oct 13).
The notes below are PickRV's editorial record. Only the figures in the strip at the top of the page, each with its link and date, were re-read on the park's own pages.
Rocky Mountain National Park concentrates more than 60 peaks above 12,000 feet, alpine tundra, and the Continental Divide into a single Colorado high-country corridor. Trail Ridge Road climbs to 12,183 feet — the highest continuous paved road in any U.S. national park — and connects the busier Estes Park side with the quieter Grand Lake entrance.
Late June through mid-September keeps Trail Ridge Road open end-to-end; September brings clearer light and elk-bugling season in Moraine Park and Horseshoe Park.
Moraine Park and Glacier Basin accept RVs up to about 40 ft and 35 ft respectively; Timber Creek accepts up to about 30 ft. None of the park campgrounds have hookups, and a timed-entry reservation is required for most summer arrivals.
What the official site doesn't tell you
NPS.gov long said 'no hookups in any RMNP campground,' but that's now outdated for the headline RV site: after the 2025 utility rehab, Moraine Park reopened with 49 ELECTRIC sites (20/30/50-amp) in Loops B and C — the only powered sites in the park. There's still no water or sewer hookup anywhere, so arrive with full fresh tanks and plan to use the dump stations at Moraine Park or Glacier Basin. Second trap: a campground reservation is NOT your entry permit. In 2026 you also need a timed-entry permit — Bear Lake Road corridor through Oct 19, rest of park through Oct 13 — released monthly starting May 1 and gone within minutes. Third: do not point a 40-footer or any towed rig up Old Fall River Road — it's 9.4 miles of one-way gravel that bans vehicles over 25ft and all trailers. Drive your tow vehicle instead. Fourth: Trail Ridge Road is your only east-west crossing and it's closed mid-October to late May, so a west-side Timber Creek booking can mean a multi-hour detour in shoulder season.

Boondock alternative within 20-40 min — free dispersed sites with no hookups/water; check current USFS fire restrictions and stay limits before relying on it
Arapaho & Roosevelt National Forests dispersed camping outside the park — e.g. along the Peak to Peak Highway (CO-7/72) south of Estes Park
Full season: Moraine Park Campground: year-round (summer reservation-only; winter ~Oct 20 onward first-come). Glacier Basin, Aspenglen, Timber Creek: roughly late May through early-to-mid September
Limited access: Trail Ridge Road open late May to mid-October only (closes to through travel for winter); Old Fall River Road usually opens early July and closes for the season in October
Known closures:
Hidden — not on the official map
Timber Creek Campground (west / Grand Lake side)
Far quieter than the Estes side and easier to book; 30ft max, dry camping — but remember Trail Ridge Road closes in winter, leaving a long detour back east
Peak to Peak Highway dispersed camping (USFS)
Free Arapaho-Roosevelt NF dispersed sites along CO-7/72 south of Estes Park — basecamp the big rig free, then drive a toad into the park

Per-state legal callout · CO
Standard Class R license covers motorhomes under 26,001 lbs
Colorado's ordinary Class R license is defined as any motor vehicle with a GVWR of less than 26,001 lbs as a single unit or in combination (15 or fewer passengers, no hazmat) — so it covers personal-use motorhomes and typical trailer combos. A single vehicle of 26,001+ lbs GVWR requires a Class B CDL; a combination over 26,000 lbs GCWR towing 10,000+ lbs requires a Class A CDL.

Operators 18+; ages 14-17 need a safety certificate; ANS stamp to launch
In Colorado anyone operating a motorboat or personal watercraft must be at least 18, and 14- to 17-year-olds may operate one only after completing and passing a state-approved boating safety course and carrying the certificate. Operators over 17 need no course, though CPW strongly encourages one. Every motorized or trailered boat and sailboat also needs an Aquatic Nuisance Species stamp and a certified ANS inspection before it launches.

Colorado OHV permit $26.25/yr — same price for residents and visitors
Any OHV used on Colorado public land needs a CPW registration or permit for the April 1 to March 31 year. Residents and non-residents both pay $26.25, which includes a $1.25 Search and Rescue surcharge, and the fee cannot be prorated for a partial year. Helmets are required for operators and passengers under 18 on public OHV trails.

0.08% BAC per se; 5 ng THC creates only a permissible inference
Colorado charges DUI per se at a BAC of 0.08 or more, measured at the time of driving or within two hours of it. There is no equivalent per-se charge for drugs: 5 ng/mL or more of active delta-9 THC in whole blood only allows a court to infer that the driver was under the influence, and the driver can rebut that inference. Cannabis is legal for adults 21 and over, but driving impaired is still prosecuted as DUI.
