Bambusal (the bamboo forest river)

A shaded river off Calle Uvita, reached by a short hike in past a stand of enormous bamboo. Free parking, no bathrooms, real shade, and a current strong enough to take a small child off their feet. The one place near here we bring a cooler and stay all day.

What to expect

You park near the bamboo — and it's the real thing, huge stands of it, which is how you know you're in the right place. From there it's about a ten-minute hike in to the river. It's easy enough that Papaw does it without help, and easy enough that Río walked it himself at three, which is not true of most river access on this coast.

What you get is shade, which after a morning at Whale's Tail or Ventanas is the whole point. The swimming area itself is open to the sky in places, but there's tree cover along the banks and you're never short of somewhere to get out of the sun. We don't put the kids in full-length rash guards here the way we do on the sandbar.

This is the place we treat as a full day rather than an outing. We bring coolers. We've cooked lunch on the rocks in the river. There's nothing to buy and nowhere to buy it, so whatever you want, you carry in — and out.

The current deserves respect. Río got away from me in shallow water once, wearing a life vest, and I had to run down the bank after him. He was never in danger of drowning and could most likely have stood up, but running through shallow water after a child moving faster than you can is a bad feeling and I don't want anyone to meet it unprepared.

Any river here can rise on rain you can't see. We check the weather in the mountains before we go, and if the water is brown and it's raining upstream, we skip it and do something else.

Who this works for

The whole-crew test · toddlers to grandparents
Toddlers (1–4)

We brought Mar here at 1 and it was fine, and Río walked the trail in himself at 3. Ten minutes on a path, shade at the end, and shallow water to sit in. Bring a life vest or floaties and stay within arm's reach — the current is the one thing to respect — but this is a place we'd bring a toddler without hesitating.

Kids (5–12)

Good swimming, shade, rocks to climb on, and a whole day's worth of river. Bring floaties if they need them and keep the current in mind — it moves faster than it looks.

Teens

Swimming, rocks, and a river that rewards being left alone in it. We haven't travelled here with teens ourselves, so this one is a read rather than a report.

Parents

This is the trip where you actually sit down. Shade, a cooler, rocks to spread out on, and no sun to manage. The only thing you're watching is the water.

Grandparents

The best grandparent option we've found on this coast. The hike in from the parking is short and easy — Papaw does it unaided — and once he's there he sits on the rocks or gets in the water. Shade the whole time. The catch is bathrooms: there are none at all, so plan the day around that before you bring someone who needs them.

In their words

Verbatim · recorded on site or at dinner that night

That's the river where I floated away

— Río, age 6

He says this every time it comes up. He was in a life vest, in shallow water, and the current carried him faster than I could walk. He remembers it as an adventure. I remember it differently.

— Mar, age 4

Nothing yet. She swims and she's happy here, but she hasn't made a memory of this place the way her brother has.

2026Río 6 · Mar 4

Unchanged, which is the point. We've come every year since 2023 and it is always the same river doing the same thing. Both kids swim it now. Río still tells anyone who'll listen about the time he floated away.

VERDICT: Same as it's been every year. That's the appeal.

Things we wish we'd known

  • There are no bathrooms. None. Our kids use the woods and we plan the day around it.
  • Free parking, no attendant, nothing to buy. Everything you want for the day comes in with you.
  • Check the weather in the mountains, not just overhead. Rivers here rise on rain falling somewhere you can't see. Brown water plus upstream rain means we go somewhere else.
  • The current is stronger than it looks. Río got away from me in shallow water in a life vest and I couldn't catch him on foot.
  • Bring floaties if your kids want them. There's real swimming here.
  • We don't bother with full-length rash guards here. The shade does the job.
  • Weekends and holidays get crowded. Weekdays are quiet.
  • Wear shoes that can go in and out of the water. Sturdy sandals like Tevas for adults, Crocs for the kids — you're on rock the whole time, wet and dry.
  • There are usually dogs here, mostly off-leash. Take that as a plus or a minus depending on your family. People have been respectful about it every time we've gone.
  • We've cooked on the rocks in the river. It's public land and we're not telling you to build a fire — if you don't already know how to do it safely and clean up completely, don't.

Nature School · Bamboo, and why the river is cold

Stand at the base of the bamboo and look up. Ask the kids why it's so much cooler here than at the beach, and where the water is coming from — it starts in the mountains you can see from the highway.

Conversation starter: "Where was this water yesterday?"

Nothing. Make it the day. Pack a picnic, eat lunch on the rocks, and don't plan anything after it. See the full Uvita guide.
