Two windows — and how much of the day survives
The figures look harmless until you set them against the opening hours. Mirador del Río opens at 10:00 and the closure runs to 11:30: the first hour and a half of the visiting day falls inside the window, leaving the afternoon up to 17:00. At Castillo de San José it is the other way round — it opens at 11:00, the closure starts at 11:30, and afterwards five clear hours remain until 18:00, including for the MIAC, the contemporary art museum inside the fortress. What closes is the access, not the building: nowhere does it say either site will shut.
The hours are not arbitrary. Saturday's stage runs 115 kilometres from Club La Santa to Puerto del Carmen; one of the three hill time trials is precisely the climb to Mirador del Río, 8.5 kilometres at 3.6 per cent, and Castillo de San José is the “Guayo Rodríguez” regrouping point where the field is brought back together (Yaiza te Informa, 30 September; Objetivo Triatlón, 2 October 2026). Lancelot Digital speaks of “cortes puntuales y dinámicos de tráfico”: the times mark the frame, not a road shut for three and a half hours on end.
The ticket problem is not where you would expect it
CACT sells online-only, fixed-time tickets for two of its sites. The FAQ puts it like this: “En Montañas del Fuego y Cueva de los Verdes la entrada solo se puede comprar online y siempre con fecha y hora concretas.” Such a ticket is valid only for the day and hour chosen, and Cueva de los Verdes, according to the general terms, has no ticket office at all.
But neither of those two sites appears in the closure notice. The ones named are Mirador del Río and Castillo de San José, where you can also buy at the counter: miss your arrival there and you lose the journey, not the ticket. The sharp case is the reverse one. Montañas del Fuego (30.00 euros) and Cueva de los Verdes (17.00 euros) have immovable time slots and carry no warning at all — even though the route runs through Timanfaya according to Lancelot Digital. Whether there will be closures there, CACT does not say.
Exchange or refund: what the terms say
Nobody has answered outright what happens to a missed time slot, but the general rule is there in CACT's Condiciones Generales. There is no right of withdrawal for general admission tickets: CACT invokes the exception for leisure services with a set date in Royal Legislative Decree 1/2007. It follows that “CACT Lanzarote no admite cambios ni devoluciones una vez realizado el pago”. A second clause rules out refunds for delay, cancellation, strike or force majeure.
There is one door, and it is narrow: if CACT itself cancels a service or event, the buyer may choose between a new date, an equivalent alternative, or a 100 per cent refund — but “sujeto a la viabilidad y aprobación”, subject to operator EPEL-CACT's approval. Whether a closure CACT itself announced counts as such a cancellation is written nowhere; what is closed is the road, not the house. Anyone wanting to ask will find the address info@centrosturisticos.com in the FAQ. cita.news did not ask.
Sunday — and what was missing this morning
On Sunday 4 October everything shifts south: Tías from 08:00 to 09:30, Yaiza from 08:30 to 11:15 and from 11:15 to 12:15, Tinajo from 10:30 to 12:15 and from 11:50 to 13:15 (Club La Santa, 18 September 2026). Yaiza is the only municipality to have published street-level detail for 2026, in two sheets of Club La Santa's safety plan: the LZ-30 (La Geria–Uga) from 08:30 to 09:30; the LZ-702 (Uga–Maciot) from 08:45 to 09:45; the LZ-2 between Playa Blanca and Yaiza from 09:00 to 10:40; the Calles Montañas del Fuego, La Orilla and El Rincón from 09:30 to 10:45 — and, as the longest window, the LZ-67 between Yaiza and Mancha Blanca from 09:00 to 12:15.
The LZ-67 is the road by which Sunday's route heads for Timanfaya. Montañas del Fuego opens at 09:30 and sells only fixed-time tickets; there is no CACT notice for Sunday at all.
What is missing, as of 2 October 2026 at 08:12 UTC: a street-level list for Saturday. The detailed lists circulating online are last year's (Haría, 26 September 2025; Lancelot Digital, 3 October 2025); in both editions the Cabildo filled the gap only one to three days ahead. cabildodelanzarote.com and arrecife.es were unreachable for us: their TLS certificate chains are broken. Teguise, Tías and San Bartolomé had published nothing.
