Active Costa Rica: Waterways & Wildlife — Self-Launched

Fly into Juan Santamaría International Airport (SJO). Skip the private transfer and take an official airport taxi or Uber to your hostel in Barrio Amón or Barrio Escalante — 25-35 minutes, roughly £15-20 (there's no cheap public bus that beats the taxi for a late arrival). Check in, walk a couple of blocks for a casado or a plate of gallo pinto, and get an early night. Buy a Kolbi or Claro SIM at the airport arrivals hall (~£8 for a 30-day data package) — it's a lifesaver for booking shuttles on the road. Pre-load the Rome2Rio and Moovit apps.

🚌Airport taxi/Uber to central San José, ~£15-20

🛏Selina San José or Hotel Casa 69, private dorm or budget double (~£22-30)

• →Arrive San José
• →Buy local SIM card
• →Evening walk in Barrio Amón

Take the 6am or 9am direct bus from San José's Gran Terminal del Caribe to Cariari (~4 hrs, ~£5-6, book a day ahead at the terminal or via the Transportes Caribeños counter). From Cariari, a local bus or shared minibus runs to the La Pavona dock (~1.5 hrs, ~£4). At La Pavona you'll wait for the public boat, which shuttles passengers and cargo down the canals to Tortuguero village (~1.5 hrs, ~£5-7). Alternatively most lodges offer a combined shuttle + boat transfer from San José for ~£32-38 if you'd rather not juggle connections — worth it on this leg. Guesthouses in Tortuguero village sit right on the canal; dinner is a big plate of Caribbean rice and beans with fresh fish.

🚌San José–Cariari public bus (~£6) + Cariari–La Pavona minibus (~£4) + public boat to Tortuguero (~£6); combined lodge shuttle option ~£35

🛏Cabinas Tortuguero or Miss Junie's-style village guesthouse, double room (~£25-32)

• →Cross the Tortuguero canals by public boat
• →Sea Turtle Museum in the village
• →Tortuguero village stroll at dusk

Book a small-group canoe or panga tour the evening before — the 5:30 or 6am slot is far better for wildlife than the mid-morning one. Local guides in Tortuguero charge around £25-35 for 2-3 hours of canal cruising, and they'll find you howler monkeys, white-faced capuchins, caiman, basilisk lizards, sloths and dozens of the 300+ bird species logged here. In the nesting season (roughly late July to October, hatchlings from late August to November), green turtles come ashore at night — a licensed guide escort to the beach (~£22-28) is mandatory for turtle watching anywhere in the park. Afternoon: walk the easy Cerro Tortuguero or El Jaguar trail or just laze in a hammock by the water.

🚌On foot and by boat within the village and canals

• →Guided dawn canoe tour of Tortuguero waterways (~£30)

Retrace the canals by public boat to La Pavona, then bus to Cariari and on to Puerto Viejo de Sarapiquí — total travel time around 4-5 hours plus waiting, ~£12-15. Buses up here are the classic old-school chicken-bus style: cheap, friendly, slow. Base yourself near the river. In the evening, book a night walk at Tirimbina Biological Reserve (~£22-25 including the suspended bridge crossing) — a local biologist guide sweeps a torch over the forest and the eyeshine of frogs, kinkajous, insects and sleeping birds flickers back at you. It's one of the easiest and most rewarding night walks in the country.

🚌Public boat to La Pavona + local buses to Puerto Viejo de Sarapiquí (~£13 total)

🛏La Quinta de Sarapiquí-style lodge or Hacienda Río Sarapiquí cabinas (~£25-35)

• →Tirimbina Biological Reserve night walk with guide (~£24)

Take a morning tour of a working family pineapple farm near La Virgen de Sarapiquí (~£18-22 direct with the farm, including tasting) to see how smallholders grow the crop without synthetic pesticides. Then catch the afternoon bus or a shared shuttle onward to La Fortuna, at the foot of Arenal (bus via Ciudad Quesada ~3 hrs and ~£5, or a door-to-door shared shuttle ~£22). La Fortuna is backpacker central: hostels with volcano views, cheap sodas, and every tour under the sun. Spend the late afternoon walking the free trails around the town for your first look at Arenal's perfect cone, then dip into one of the riverside hot springs — several free spots (El Chollín, across the bridge) flow warm all year.

🚌Public bus Sarapiquí–La Fortuna (~£5) or shared shuttle (~£22)

🛏Arenal Backpackers Resort or Selina La Fortuna, dorm or private (~£18-28)

• →Family pineapple farm tour (~£20)
• →Free riverside hot springs at El Chollín
• →Volcano-view sunset walk

Book a half-day Costa Rican cooking class with a local family project (~£35-45) — you'll pick vegetables and herbs from the garden, learn to shape tortillas by hand and cook over a wood fire, and eat what you make. Combine it with a morning visit to an organic farm that produces honey and preserves. If you'd rather keep it cheap, La Fortuna's municipal market and the produce stalls are a great self-catering alternative for making your own casado, and the town's soda restaurants serve a full set lunch for £6-8.

🚌Local taxi or walk to the class location (~£5 return)

🛏Same La Fortuna hostel or budget hotel (~£18-28)

• →Costa Rican farm-to-table cooking class (~£40)

Enter Arenal Volcano National Park independently — the entrance fee is around £15 and the Los Miradores and Coladas trails are well marked, walking through secondary rainforest and across lava fields from the 1968 and 1992 eruptions. The viewpoint over Lake Arenal is the money shot. Get there early (the park opens 8am) before the clouds roll in. Afternoon options: the La Fortuna Waterfall (~£15 entry, 500 steps down to a spectacular swimming hole), the Arenal 1968 lava fields trail, or a canopy tour / hanging bridges / Lake Arenal kayak. Book any of these the day before through GetYourGuide or the hostel desk.

🚌Local bus or taxi to the national park entrance (~£6 return)

🛏Same La Fortuna hostel or budget hotel (~£18-28)

• →Arenal Volcano National Park self-guided hike, Los Miradores + Coladas trails (~£15 entry)
• →Optional La Fortuna Waterfall (~£15) or canopy tour (~£45)
• →Optional Lake Arenal kayak or stand-up paddle (~£35)

The classic backpacker route to Monteverde is the jeep-boat-jeep: a minibus from La Fortuna to the Lake Arenal dam, a 30-minute fast boat across the lake, then a shared minibus up into the Tilarán mountains to Santa Elena. Book through any La Fortuna hostel or agency the day before for ~£25-30, with pickup at your lodging and roughly 3.5-4 hours door to door. Monteverde's cloud forest sits at 1,400m so it's noticeably cooler — pack a fleece and a rain shell. Afternoon: wander Santa Elena town, sort out park tickets, and eat at one of the local sodas.

🚌Jeep-boat-jeep shared transfer La Fortuna–Monteverde (~£27)

🛏Pension Santa Elena or Monteverde Backpackers, dorm or private (~£18-28)

• →Lake Arenal boat crossing
• →Santa Elena town orientation

Make a full adventure day at Selvatura Park (or the equivalent Original Canopy Tour / Monteverde Extremo set-up). Book direct or via GetYourGuide: the hanging bridges walkway system through the canopy runs ~£30, the butterfly garden ~£12, and the zip-line course — a long series of cables strung through the cloud forest, finishing with a Tarzan swing — runs ~£45-55. If you only do one thing in Monteverde, most travellers say the zip-line is it. Alternatively, the Curi-Cancha Reserve and Monteverde Cloud Forest Reserve both have superb, quieter trails (~£18 entry) where you might catch a resplendent quetzal.

🚌Shuttle to Selvatura Park included with most bookings, or taxi (~£6)

🛏Same Santa Elena hostel or lodge (~£18-28)

• →Selvatura canopy hanging bridges walk (~£30)

Take a shared shuttle or public bus combination down to the Rincón de la Vieja area in Guanacaste (Guanacaste dry forest — you'll notice the climate change completely). The straightforward option is a shared shuttle from Santa Elena to Liberia or Curubandé (~£25-30, 3-4 hrs); from Liberia, a taxi to a lodge near the park gate runs ~£15-20. Lodges here tend to be a bit out of town, so stock up on supplies in Liberia. Afternoon: relax by the pool or walk to a nearby waterfall for a swim.

🚌Shared shuttle Monteverde–Rincón/Liberia (~£28) + local taxi (~£18)

🛏Hacienda Guachipelín or Buena Vista del Rincón-style lodge, budget room (~£30-38)

• →Scenic drive through Guanacaste
• →Afternoon swim at a local waterfall
• →Optional evening hot springs

Pay the ~£15 park entrance and hike the Las Pailas loop independently — about 3km through dry tropical forest past roaring fumaroles, bubbling mud pots (Las Pailas means 'the cauldrons'), and steaming vents at the base of the volcano. Toucans, spider monkeys, coatis and white-tailed deer are all regularly spotted. In the afternoon, book one of the adventure add-ons that made Rincón famous: canyon canopy zip-line, river tubing down the Colorado River, or a horse ride to the Oropéndola waterfall (~£35-55 each, book at your lodge). Finish the day in the hot springs and volcanic mud baths (~£20-25).

Travel to the Guanacaste Pacific coast — the classic finish to this route is the sheltered sandy bay at Playa Carrillo or the laid-back surf town of Sámara, both shaded by coconut palms with calm swimming water. From Liberia take a public bus to Sámara (~2 hrs, ~£4) and then a local bus or taxi to Carrillo, or a shared shuttle door-to-door (~£20). Check into a beach hostel or cabina and spend the afternoon doing nothing much: swim, watch the fishing boats come in, and find a cheap marisquería for grilled fish.

🚌Public bus Liberia–Sámara (~£4) + local bus or taxi to Carrillo (~£4) or shared shuttle (~£20)

🛏Sámara or Carrillo beach hostel/cabina, double (~£28-38)

• →Afternoon on the beach
• →Swim in the sheltered bay
• →Sunset from the headland at Carrillo

Book a small-group dolphin-watching and snorkelling boat trip direct with a Sámara or Carrillo operator (~£40-50 for 3-4 hours, including snorkel gear and often fruit and drinks). A morning departure has calmer water and better dolphin sightings — spinner dolphins, and sometimes humpbacks in season (Dec-April). The afternoon is yours: rent a kayak or stand-up paddle board (~£12/hour), take a surf lesson in Sámara (~£35 for a group lesson, one of the best beginner breaks in Costa Rica), or just stay put on the sand.

🚌Walk or short taxi to the boat departure point (~£4)

🛏Same beach hostel or cabina (~£28-38)

• →Dolphin-watching and snorkelling boat trip (~£45)
• →Optional surf lesson in Sámara (~£35)

Join an early mangrove kayak or boat tour (~£35-45) through the estuary — a completely different ecosystem to everything else on this trip, with herons, kingfishers, crocodiles basking on the banks and howler monkeys overhead. Guides are local and usually freelance; ask at your hostel or book through Klook/GetYourGuide. Spend the rest of the day beachside, then have a final dinner of fresh ceviche or a whole grilled snapper as a proper send-off. Pack tonight if you're on an early bus tomorrow.

🚌On foot and by boat locally

🛏Same beach hostel or cabina (~£28-38)

• →Mangrove kayak or boat wildlife tour (~£40)

Take a morning public bus or shared shuttle from Sámara back to San José (~4-5 hrs; bus ~£9 with Transportes Delio Morales, shared shuttle ~£35-40 door-to-door). If you have an afternoon or evening flight from SJO, a shuttle is worth the splurge to avoid missed connections — the public bus drops at the San José terminal and you'd then need a taxi to the airport (~£12-15). If you have a few hours spare in the capital, duck into the Museo Nacional or the Mercado Central for a final gallo pinto before heading home.

🚌Public bus Sámara–San José (~£9) or shared shuttle to SJO (~£38)
