Lake Arrowhead Waterfalls
The classic Lake Arrowhead waterfall is at Heart Rock — a seasonal waterfall next to the heart-shaped pothole, best in spring and after rain or snowmelt (it slows to a trickle or dries up by late summer). The other real water is along Deep Creek, which has cascades and pools on the way to the hot springs. Both are short-to-serious hikes covered on this site. Expect modest seasonal falls rather than year-round cataracts.
Getting there
Get directions →Heart Rock: the classic seasonal waterfall
The waterfall most people mean by 'Lake Arrowhead waterfall' is on the Heart Rock Trail near Crestline — a small seasonal falls right beside the famous heart-shaped pothole carved into the granite. It's a short, family-friendly hike (about 1.5–2 miles round-trip), which is why it's the go-to.
The catch is timing: the waterfall is seasonal. It flows best in spring and after winter storms or snowmelt; by mid-to-late summer it often slows to a trickle or dries up entirely, even though the heart-shaped rock is worth the walk year-round. If the waterfall specifically is your goal, go in spring or within a few days of significant rain or snowmelt.
Deep Creek: cascades and pools
For more water, Deep Creek is the other option — a year-round creek with cascades, small falls, and pools, most famous for the hot springs at the end. This is a serious hike, though: roughly 5 miles round-trip with a hot, exposed climb out, and it's a designated Wild Trout stream with its own rules. It's not a casual waterfall stroll like Heart Rock. Read the full Deep Creek guide — including the safety and access realities — before planning it.
What to expect (and bigger falls nearby)
The immediate Lake Arrowhead area is mountain-lake and forest country, not a waterfall destination. Heart Rock's falls are modest and seasonal, and Deep Creek's water is a bonus on a hard hike, not a roadside attraction. If you're after big, reliable waterfalls, the San Bernardino Mountains and nearby ranges have larger ones (Big Falls near Forest Falls is the region's tallest year-round waterfall, well east of here) — but those are separate trips. Around Lake Arrowhead, plan the waterfall visit for spring and pair it with the Village and a swim lake.
Before you go
A few practical notes: many San Bernardino National Forest trailheads require an Adventure Pass ($5/day or $30/year) or an America the Beautiful pass — each trail page notes whether you need one. Heart Rock's small trailhead fills early on weekends. Wear real shoes (rock near falling water is slick), keep kids close at the pothole and pools, and check trail conditions after big storms, when water is highest but crossings can be dangerous.

When is the best time to see the Heart Rock waterfall?
Spring, and within a few days of significant rain or snowmelt. The waterfall is seasonal — it often slows to a trickle or dries up by mid-to-late summer, though the heart-shaped rock itself is worth the hike year-round.
How do you get to the Heart Rock waterfall?

Is there a waterfall you can hike to near Lake Arrowhead year-round?
Deep Creek runs year-round with cascades and pools, but reaching it is a hard ~5-mile round-trip hike with a hot, exposed climb out — not a casual waterfall walk. For an easy option, Heart Rock is better, just seasonal.
