How to check that an excursion is legal, island by island
You already know why it pays to go with an operator that plays by the rules. What's left is the practical part: how you check it yourself, before you pay, without relying on the word of whoever is selling it to you. And there's a little-known trick that works across the whole of the Canaries: the most famous natural spaces have official access rules, and a legal operator follows them to the letter. The one working off the books tries to dodge them, and that's exactly where they give themselves away.
This is the final piece in our series on legal excursions in the Canary Islands. A useful, pocket-sized wrap-up: first, how to verify the company; then, island by island, the access rules a professional actually meets.
The three documents you can ask for (and check)
A serious operator will show you three things without flinching. We flagged this in https://islas24.info/en/blog/how-to-spot-legal-excursions-canary-islands; here we bring it down to earth.
The registry number. Every active-tourism company is listed in the Canary Islands General Tourism Registry and has an identifying code. Ask for it before you book. And here's the good part: the Canary Islands Government publishes that registry openly. On the open-data portal (datos.canarias.es) there's a dataset, "Actividades de turismo activo inscritas en el Registro General Turístico de Canarias", that you can download as CSV, XLSX or JSON, updated daily. It's not a search box: it's a downloadable list where you cross-check the company's name and its code. If the operator isn't there, that's a bad sign.
The insurance. The rules require public liability insurance and accident insurance covering participants, rescue included. Ask whether the activity carries insurance; an operator in good standing confirms it without any fuss.
The guide's qualification. The official tourism guide (cultural visits and heritage) holds an accreditation from the Directorate-General and a licence card. For mountain or adventure activities, the instructor must hold the professional qualification required for that specific activity. You can ask to see the card or the certificate.
If you book a car transfer instead of a walking route, the paperwork is different (transport licence, not active-tourism registry). We break it down in https://islas24.info/en/blog/private-car-excursion-legal-canary-islands.
Island by island: the access rules that give the legal ones away
This is the most practical filter of them all. Many Canary natural spaces have access regulated by official rule. A legal operator books the slots, pays the fees and arranges the correct transport. The irregular one takes you "off the books" and, more and more often, won't even get you in.
Tenerife
Barranco de Masca. Since 2025 the trail is regulated: you have to book a slot on the official site (www.caminobarrancodemasca.com), show up half an hour before at the visitor centre for the check (booking, ID and gear), and use a mandatory transport (a TITSA charter bus from Santiago del Teide). Without that transport, there's no access to the descent. Mountain footwear is mandatory, there's a limited daily quota, the activity is not allowed for children under 8, and the mandatory accident insurance is included in the fee. The price for non-resident adults is 40,66 € (IGIC included), for trail entry only; the bus (TITSA, line 355 from Santiago del Teide) and the exit boat are paid separately (heavily reduced for Canary residents, refunded for Tenerife ones). And here's the logistical key: you are required to leave the ravine by sea towards Los Gigantes, and at the access control you must show both the trail booking and the boat or kayak ticket. An off-the-books organiser can't give you that closed package nor the proof the control requires. See also https://islas24.info/en/blog/masca-gorge-complete-hiking-guide.
Pico del Teide. To set foot on the summit via the Sendero nº 10 Telesforo Bravo (the stretch from La Rambleta, at the top of the cable car, to the crater) you need a mandatory advance booking from the National Park, personal and non-transferable, arranged on the official platform Tenerife ON (tenerifeon.es). And since 19 January 2026 there's also an eco-tax for non-residents in the 9:00–17:00 window: 15 € per person if you go up on your own, but only 10 € if you go with an authorised active-tourism company (which also handles the quota for you). Going without a permit can mean a fine of up to 600 €. It's probably the best example of why legal pays off: a guide in good standing saves you money and paperwork.
Punta de Teno. Access by private car along the TF-445 road is restricted during the day: in summer you can't drive it from 9:00 to 20:00, and in winter from 10:00 to 19:00. During those hours you only get in by bus (TITSA line 369), taxi or bicycle. It's the very case that has stirred controversy: locals and visitors complain that access is limited to a paid bus or taxi in the middle of the day. The takeaway for the traveller is simple: a legal operator arranges the permitted transport; the irregular one tries to sneak in by car against the rule, risking a fine and being turned away.
Gran Canaria
Roque Nublo. Since 2025, access to the trail (S-70) via the Degollada de la Goleta requires a free advance booking in the busiest window (approx. 9:00 to 17:00), through reservasroquenublo.com, run by the Cabildo of Gran Canaria. But the real filter is the car: the Degollada de la Goleta car park is closed to the general public (only accessible parking spaces), so now you have to leave the vehicle in Tejeda or at the Cruz de los Llanos and go up on the shuttle bus (Global line 18). An illegal operator will try to "drop you off" quickly on the road to dodge the check; the legal one already has the booking and the transport sorted.
La Palma
Caldera de Taburiente. The park is open access for entering and leaving the same day, but there are regulated points. Access to the La Cumbrecita viewpoint is time-restricted (approx. 8:30 to 16:00) and requires a free slot-and-time booking. Camping also needs a free permit. Both are arranged through the National Parks central booking office.
On the coast, two useful warnings after the volcano: the beach at Puerto Naos has reopened under a strict gas-sensor system ("Alerta CO2"), and the access stairway to the spectacular Playa de Zamora Grande is sealed off due to rockfall risk. If an organiser promises to take you down to Zamora Grande, be wary: a legal guide never takes you into an area closed for safety.
La Gomera
Garajonay National Park. There's no entry barrier here and much of the network is free access or self-guided. But there are reserve zones and trails that do require authorisation, and staying overnight inside is prohibited. A guide who knows the park knows exactly which route can be done without a permit and which can't; that knowledge is part of what you're paying for.
Lanzarote and La Graciosa
In Lanzarote, the Cabildo's major centres (CACT: Timanfaya, Cueva de los Verdes) now require an online ticket with a time slot; at Timanfaya it's no longer sold at the ticket window. A guide with priority channels saves you the queue under the sun or missing out at the Montañas del Fuego.
On La Graciosa, the eighth island, there's no tarmac: you get around on foot, by bike or in the authorised 4x4 taxis, whose number is strictly limited (around fifteen licences). Booking a "4x4 safari" with someone who doesn't hold an official licence means fuelling pirate transport in a very fragile space. And remember the island's golden rule: every bit of waste you generate comes back with you on the boat to Lanzarote.
Fuerteventura and El Hierro
On these islands the pattern repeats across their protected spaces (nature parks, reserves, special protection zones): access more or less free in general, with specific uses and trails subject to authorisation from the Cabildo or the managing body. The golden rule doesn't change: if your excursion enters a protected space, ask the operator who arranges the permit. If the answer is "you don't need one" and it turns out you do, you already know who not to go with.
Did you know? The Canary Islands' active-tourism company registry is open data: anyone can download the up-to-date list (CSV, XLSX or JSON) from datos.canarias.es and check whether an operator is genuinely registered. Transparency works in your favour.
Did you know? On wild beaches like Cofete (Fuerteventura) or El Verodal (El Hierro), a professional guide explains the geology of the place, but never invites you to swim: the ocean here is treacherous because of strong rip currents, and a red flag flies much of the year. If your instructor doesn't warn you of the danger or encourages you to go in where there's a red flag, that's a sure sign they don't have the safety training the law requires.
One rule that works for everything
You don't need to memorise every rule on every island. All it takes is one reflex before booking: ask for the registry number, ask about the insurance, and ask who arranges the permit or transport for the place you're going to visit. A legal operator answers all three without hesitation, because all three are part of their job. The one who gets nervous about any of them is giving you the answer you need.
Choosing well takes nothing away from the experience: it secures it. And in the Canaries, more and more, doing it right is also the only thing that lets you in through the front door.
