Direct answer
Lake Titicaca straddles Peru and Bolivia; prepare for high altitude, border/visa rules for each country, variable weather, and a focus on indigenous Aymara/Quechua cultures. Plan logistics (island visits, boats, permits) ahead and respect local customs.
Visa & entry requirements
- Peru: Many nationalities get 90-day tourist stay or visa-free entry; check Peru’s consulate/immigration for updates.
- Bolivia: Several nationalities get visa-free entry for 30–90 days; some need e-visas or consular visas. Check current requirements before travel.
- Border crossings: There are official crossings between Peruvian and Bolivian shores (e.g., Puno–Copacabana). Always carry passport, entry stamps, and be aware some boat routes require immigration checks. Avoid unofficial crossings.
Best time to visit
- Dry season (May–October): Sunny days, cold nights, clearer skies—best for trekking, boat trips, and photography.
- Shoulder/green season (April, November): Fewer crowds, some rain, landscape greener.
- Wet season (December–March): Frequent rain, rougher lake conditions, some services reduced.
Altitude & health
- Lake level ~3,812 m (12,507 ft). Respect altitude: allow 1–2 days to acclimatize in Puno, Copacabana, or similar.
- Symptoms: headache, shortness of breath, nausea. Rest, hydrate, avoid alcohol, eat light meals. Consider acetazolamide (Diamox) if prescribed by a doctor.
- Medical resources: Limited in small towns and islands—carry basic meds, travel insurance with medical evacuation is strongly recommended.
Safety tips
- Weather & water: Winds can pick up quickly—choose licensed boats, life jackets, and confirm weather before trips.
- Personal safety: Lake towns are generally safe but use normal precautions—avoid poorly lit streets at night, watch belongings in markets and on buses.
- Scams: Pre-book reputable tour operators for islands (Uros, Taquile/Amantani) and ask about included meals, homestay fees, and return times.
Local customs & etiquette
- Language: Spanish, Aymara and Quechua widely spoken. Learn basic greetings (e.g., "hola", "sumaq kawsay"/local phrases) and carry a phrasebook or offline translator.
- Dress & respect: Ask before photographing people—many communities are used to tourists but expect politeness. Remove hat and greet elders; share small gifts if staying overnight (sweets, school supplies) but ask hosts what’s appropriate.
- Homestays: Follow host rules (mealtimes, fire/wood use), bring modest clothing for temples/churches.
Currency & money
- Peru: Peruvian sol (PEN); Bolivia: Boliviano (BOB). Major towns accept cards (Puno, Copacabana) but islands and small vendors often cash-only.
- ATMs: Available in larger towns; bring enough cash for island fees, tips, and small purchases. Currency exchange services available in border towns and airports.
Transportation & getting around
- Airports: Juliaca (near Puno) and El Alto/La Paz (for Bolivian side) are common arrival points. From Juliaca, bus or taxi to Puno (~45–60 min).
- By road: Buses connect Puno and Copacabana; journeys can be long—use reputable companies and keep valuables secure.
- Boats: Organized tours and public ferries run to Uros, Taquile, Amantani, and Bolivian islands (e.g., Isla del Sol). Confirm schedules, boat safety standards, and return times.
Must-know practical tips
- Clothing: Layered clothing, warm jacket, hat, gloves for cold nights; sun protection (high UV) — strong sunscreen, sunglasses, hat.
- Water & food: Tap water generally not recommended; drink bottled or boiled water. Try local dishes (trout, quinoa, cuy in some areas) but choose busy, well-reviewed spots to avoid stomach issues.
- Packing: Portable charger, copies of passport/permits, small first-aid kit, altitude medication if applicable, good walking shoes.
- Cultural experiences: Book a homestay on Taquile or Amantani in advance to experience local life. Visit Uros reed islands early morning for calmer conditions and fewer crowds.
- Photography: Sunrise and sunset are spectacular. Ask before photographing locals and offer a small tip if people pose.
Final local insights
- Respect the environment: Do not leave trash on islands; many communities have fragile ecosystems.
- Tipping: Modest tips for guides, boat operators, and homestay hosts are appreciated but not mandatory—ask what’s customary locally.
- Expect slow pace: Island life is relaxed; schedules can change due to weather—build flexibility into your itinerary.
Enjoyment tip: Take extra time to acclimatize and stay a few days—this improves comfort and lets you experience the lake’s culture, landscapes, and sky fully.
