Lake Powell is a 186-mile reservoir on the Colorado River, straddling the Arizona–Utah border and created by Glen Canyon Dam in 1963. It is the second-largest artificial lake in the United States, and it exists because the US Bureau of Reclamation flooded Glen Canyon — a landscape many early conservationists argued was more beautiful than the Grand Canyon itself. That controversy is still live among river historians, but for today's visitor the lake is simply one of the most spectacular places in the Southwest. After a July 2025 visit to Wahweap Marina and the Alstrom Point overlook, this is the guide I wish I'd had the week before I drove up from Page.

What is Lake Powell?
Lake Powell is a reservoir — not a natural lake. It was created when the Glen Canyon Dam was completed in 1963, backing the Colorado River up through Glen Canyon and several tributary canyons to form a 186-mile body of water that straddles the Arizona–Utah border. At maximum elevation it reaches a depth of 583 feet, making it the deepest large reservoir in the American West. By surface area it ranks second in the United States behind Lake Mead, its sibling downstream.
The lake and its surrounding desert are managed by the National Park Service as part of Glen Canyon National Recreation Area, which charges a $30 per-vehicle entry fee covering seven days. Inside the recreation area sits Rainbow Bridge National Monument, a separate unit protecting one of the world's largest natural stone arches.
The dam itself is worth acknowledging honestly. Building it flooded Glen Canyon, a sinuous sandstone gorge that writers like Edward Abbey and photographers like Eliot Porter considered more beautiful than the Grand Canyon. The Bureau of Reclamation built the dam anyway — the Southwest needed water storage and hydropower — and the Glen Canyon we see today exists only in old photographs. Whether that trade-off was worth it is a question the region is still arguing about, especially as drought reshapes what the reservoir can and cannot be.
How do you visit Lake Powell?
Most day-trip visitors see Lake Powell from exactly one place: Wahweap Marina, 12 minutes north of Page. That is where the Rainbow Bridge boat tours leave from and where rental boats, jet-skis and sightseeing cruises are based. But there are four main access points across the recreation area, each suited to a different kind of trip:
| Marina | Distance from Page | Best for | Cost | Parking |
|---|---|---|---|---|
| Wahweap | 12 min N | Rainbow Bridge tours, rentals | $30 entry | Plenty |
| Antelope Point | 10 min E | Kayak rentals, quieter launch | $30 entry | Limited |
| Bullfrog (UT side) | ~3 hrs (drive around) | Houseboat pickup, fewer crowds | $30 entry | Large lot |
| Hite | Remote, N end | Backcountry — low water concerns | $30 entry | Few services |
Unless you are specifically heading up to the Utah side for a houseboat pickup, your default is Wahweap. Antelope Point is the local secret for kayakers who want to paddle into the lower canyons without the bigger marina bustle.
Is the Rainbow Bridge boat tour worth it?
It depends on what you want. Rainbow Bridge is a genuine world-class landmark — a 290-foot sandstone span that is the largest natural bridge on Earth, and boat-only to reach. The tour runs from Wahweap Marina, takes about 6 hours round trip, and costs roughly $140 per person through Lake Powell Resort & Marinas, the concessioner operating under NPS contract. The route threads up the main channel, through a narrow passage into Forbidding Canyon, and finishes with a short walk from the floating dock to the viewing area.
Is it worth it? Yes, if you want the iconic view and have a half-day to spend on the water. No, if you just want Lake Powell scenery— in that case Alstrom Point (see below) delivers a bigger view for free. The tour's weak point is the pacing: most of the six hours are cruising time, and the actual bridge stop is short. Travellers who dislike long boat rides should consider a shorter canyon cruise instead.
Rainbow Bridge Boat Tour — Wahweap Marina
The full-day 6-hour boat tour from Wahweap to Rainbow Bridge National Monument. Run by Lake Powell Resort & Marinas under NPS concessioner contract — there is no other commercial operator to compare.
Can you rent a houseboat on Lake Powell?
Yes — and it is the signature Lake Powell experience if you can swing the budget and the time. Houseboats come in sizes from 2-person weekenders to 12-person luxury models with slides and rooftop decks. Minimum rental is almost always 3 nights, and prices range from roughly $2,000 for a small boat over a long weekend to $12,000+ for a week on a large boat in peak summer. Fuel and bedding are usually included; food and towing craft are not.
Two main operators: Lake Powell Resorts & Marinas (Wahweap, on the Arizona side) and Bullfrog Marina(on the Utah side, remote but a better jumping-off point for the lake's middle reaches). You pilot the boat yourself after a mandatory orientation. That puts houseboating firmly in not-for-first-timers territory — budget the 3-night minimum and bring at least one person in your group who is comfortable with larger craft.
Where is the best FREE viewpoint of Lake Powell?
Alstrom Point. This is the single most worthwhile tip in this guide. Alstrom Point is a red-rock plateau on the Utah side of the lake that gives you a 360-degree viewof Lake Powell's middle reaches — islands, side-canyons, the main channel snaking toward the dam — from several hundred feet above the waterline. It is free. There are no tours. There are no crowds. In July 2025 I saw two other vehicles in the four hours I spent up there.
The catch: the access is a 12-mile dirt road off Highway 89 that requires high clearance (ideally 4WD). Standard rental sedans do not make it. The road is not signposted, the turn-off is easy to miss, and after rain it can be impassable. GPS coordinates for the overlook are approximately 37.0589, -111.3647. Drop a pin before you leave town — cell service disappears shortly after you turn off the highway.
Go at sunrise or in the last hour of light. Bring water, because there is none up there and you cannot get help quickly if something goes wrong. If you do not have a suitable vehicle, Horseshoe Bend and the Glen Canyon Dam overlook are the realistic free alternatives — both are paved and a short drive from Page.
How does drought affect Lake Powell?
Severely, and it matters for your trip planning. Lake Powell's water level dropped dramatically between 2020 and 2024 during the most prolonged Southwest drought on record. The practical consequences for visitors:
- Boat ramps close and reopen unpredictably as the water line shifts. Some ramps that were active in 2019 are no longer usable.
- Some marinas operate at reduced capacity, particularly on the north end near Hite.
- Rainbow Bridge access can change. At very low water, the float-dock walk to the bridge becomes longer — in extreme lows, tour operators have suspended routes entirely.
- Houseboat navigation channels shift year to year; rental operators brief you on current hazards at orientation.
Before booking anything that costs more than ~$100, check two sources: the National Park Service page at nps.gov/glca for current conditions and closures, and the US Bureau of Reclamation daily water-level data for Lake Powell. Water-level data is not a trivia point here — it is the single variable that determines whether your $140-per-person Rainbow Bridge tour actually runs.
When is the best time to visit Lake Powell?
Lake Powell is a warm-water lake, and the window when the water is pleasant for swimming is late April through mid-October. The sweet spot for most visitors is September: the water is still warm from a summer of heating, the crowds have thinned after Labor Day, and the daytime air temperature is no longer the brutal 40 °C+ of July.
- April – May: Water still cool but air temperatures mild. Good for boat tours, marginal for swimming.
- June – August: Peak season, peak prices, peak heat. Houseboat rentals book out 6+ months ahead for July.
- July – September: Monsoon thunderstorms can disrupt boat tours and make some side-canyon access unsafe. Afternoon cancellations happen.
- September – October: Best balance of warm water, lower crowds and stable weather.
- November – March: Quiet. Many marinas reduce hours or services; some tours do not run at all. Good for overlooks (Alstrom Point, Glen Canyon Dam overlook) but not for getting on the water.
Frequently asked questions
How do you get to Rainbow Bridge?
By boat only. Most visitors take the 6-hour Rainbow Bridge tour from Wahweap Marina; private boaters can also make the trip. There is no practical land access — the area sits on Navajo Nation land that is managed as a sacred site, and the surrounding topography is impassable without a multi-day backcountry hike.
Is swimming allowed at Lake Powell?
Yes, in most areas of Glen Canyon National Recreation Area. Swimming directly at the base of Glen Canyon Dam is prohibited, and a few marina-adjacent zones are no-swim for boat safety. Elsewhere — beaches, side canyons, houseboat anchorages — the water is open for swimming.
Do you need a boating license for a houseboat rental?
No licence is required. Rental companies provide a mandatory orientation covering piloting, docking, generator use, and waste disposal before you leave the marina. That said, piloting a 50+ foot houseboat in open water is not a task for absolute beginners — come with a plan and at least one confident driver in your group.
What's the difference between Lake Powell and Lake Mead?
Both are reservoirs on the Colorado River. Lake Mead (formed by Hoover Dam) is larger by surface area and sits closer to Las Vegas. Lake Powell (formed by Glen Canyon Dam) is deeper, more remote, and contains Rainbow Bridge National Monument. Powell is generally considered more scenic; Mead is more accessible.
Is Lake Powell running out of water?
Not immediately, but water levels have dropped significantly between 2020 and 2024 due to prolonged drought across the Southwest. Boat ramps have closed and reopened, some marinas have operated at reduced capacity, and access to Rainbow Bridge has changed repeatedly. Check current levels on NPS.gov/glca and the Bureau of Reclamation before booking any water-dependent tour that costs more than $100.
