Best things to do in San Juan, including free and rainy-day options

San Juan is one municipality with two faces: the Laiya coastline of grey-sand coves and resorts, and the inland barangays with rivers, springs and small falls. Most visitors come for the first and add the second on a wet or windy day. The specific sites, fees and boat operations below are not confirmed by an official source — treat every price and opening as check and confirm locally before you travel.

The Laiya coast is a string of resort fronts and small public access points rather than one long free beach. Sand is grey to tan and the water is calm in the dry season. Resorts charge a day-use fee if you are not staying; walk-in fees are usually lower on weekdays and higher on long weekends. Confirm the current fee at the gate.

Boat trips to a sandbar or a snorkelling stop are the standard outing, leaving in the morning and running a few hours. Fares are per boat, so a group pays less each. Bring your own mask if you have one. Trips do not run when the coast guard issues a gale or typhoon advisory, and that decision is not negotiable.

If you want a beach with no fee, ask at your accommodation which public access points are open and safe to swim from; access changes as resorts expand.

Away from the coast, San Juan's inland barangays have rivers, spring pools and small waterfalls fed by the slopes of the Banahaw area. These are the usual substitute on a wet or windy day: they run on rain, so they are fullest in the wet months and can thin out late in a dry spell. Access is usually by tricycle or a short walk, and some sites charge a small entrance or parking fee. Which sites are open changes between seasons — ask locally before setting out.

Facilities are simple: a few cottages, a changing area, sometimes a sari-sari store. Water levels can rise fast after heavy rain upstream, and flash floods are a real risk in narrow gorges. Do not enter a river or pool during or right after heavy rain, or if the water is brown and moving fast. Check with your accommodation or the barangay that the site is open and the water is safe that day.

You do not need a resort booking to fill a day. The town centre (Poblacion) has the public market, the parish church and the plaza, and the market is the cheapest place for fruit, rice meals and snacks. A walk along the coast road at sunset costs nothing.

Public transport here is jeepney and tricycle; a short hop is a few tens of pesos, which makes hopping between the market, the church and a public beach access point a cheap half day. Bring small notes and coins.

Rain in San Juan usually arrives as heavy afternoon or overnight showers rather than all-day drizzle, but typhoon-season systems can shut the sea for days. When boats are cancelled, switch to the town centre, a resort pool under cover, or an inland site — but only if local advice says water levels are safe. Rivers and falls are the wrong choice during or right after heavy rain, when flash floods are possible.

Build one flexible day into any trip between June and November. If a storm is forecast, do not plan a boat trip on your last morning; move it earlier so a cancellation does not cost you the whole trip.

San Juan is a mid-range domestic destination, but no official source confirms current fees, fares or room rates here. Treat every figure below as check and confirm at the gate, at the boat, or on the menu before you commit. Bring cash in small notes.

Book Laiya accommodation ahead for Holy Week, Christmas and long weekends; the coast fills up and walk-in rates rise. Weekdays are quieter and cheaper. Bring cash, since card acceptance is patchy outside bigger resorts and ATMs are limited.

Sun is strong even under cloud, so use reef-safe sunscreen and a rash guard. Mobile signal is decent near the coast and weaker inland; an eSIM set up before you leave Manila saves time.
