The spiny toad, spiny common toad, or giant toad (Bufo spinosus) is a species of toad native to the Iberian Peninsula, southern France, extreme northwestern Italy, and North Africa (Morocco, Algeria, and Tunisia), with an isolated population in Jersey in the Channel Islands. For much of the 20th century, it was considered either a synonym or a subspecies of common toad Bufo bufo, but it is now classified as a separate species.
Adult males measure 58.6–112 mm (2.3–4.4 in) and adult females 65–180 mm (2.6–7.1 in) in snout–vent length. These toads feed on a number of invertebrates from earthworms to insects and woodlice. Wikipedia →

Possible
About 20% of wildlife watchers report a Giant Toad sighting in Sierra Nevada National Park on a given day, based on 14 verified sightings from GBIF citizen-science data from 2019 to 2026. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
March–April and June–August
In those months about 30% of wildlife watchers report a Giant Toad in Sierra Nevada National Park on a given day, against under 5% in September to February, the lowest months.
Between 9 pm and midnight
Across all the parks we cover, that three-hour window holds the most Giant Toad sightings with a recorded time, and about 7 in 10 of them come between 6 pm and 6 am: it is seen both by day and at night.
8th of 9
Of the 9 parks where we can rate Giant Toad sightings, Sierra Nevada National Park ranks 8th at about 20%. The best odds are in Picos de Europa National Park (Spain, about 50%), Cévennes National Park (France, about 50%) and Pyrénées National Park (France, about 50%). All parks ranked.
GBIF citizen-science records
It is estimated from how often the Giant Toad is recorded against all the amphibians logged in Sierra Nevada National Park (14 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
