Cueva del Hielo

Overview

Cueva del Hielo is a compact lava‑tube cave high on Teide’s flank (around 3,330 m) and a quirky stop if you’re hiking past the Altavista hut. It’s small but characterful: a collapsed section (a Canarian jameo) lets light into the tube, and the walls are etched with ridges from ancient lava flows.

Why it’s interesting

For centuries this was the island’s natural ice chest. From the mid‑1700s, locals harvested snow and ice here to cool food, make sweets, and for basic medical uses—stacking blocks with branches and pumice to slow melting. The cave even shows off the textbook features of a volcanic tube despite its modest size.

What you’ll see

• A roughly 48‑m‑long, slightly curved tube, up to 9 m high and 15 m wide at its broadest.
• The jameo (roof collapse) and interior lava‑flow marks—easy geology lessons in plain sight.
• A reliably cool microclimate; historically valued for snow/ice and fresh water.

Getting there

Most hikers start from the Montaña Blanca car park on TF‑21 (km 40.7) and head up toward Altavista; the spur to the cave is a short extra. Parking is limited and fills early—aim for before 10:00 or after 16:00. TITSA buses 342 and 348 run limited schedules into the park if you’d rather not compete for a spot.

On‑site realities

There are no restrooms or services at Montaña Blanca, along the path, or at the cave. Use facilities at El Portillo Visitor Center, the Parador, or the cable car base (only during operating hours) before you start. The approach is steep and at altitude—pace yourself and bring plenty of water, sun protection, and warm layers.

Safety notes

Teide’s lava tubes are protected and some are closed or guide‑only. Expect uneven footing and darkness inside any tube; bring a headlamp if you plan to peer beyond the jameo and wear sturdy shoes. If you’re continuing higher, remember the separate summit‑cone permit requirement.

Best time to visit

Early morning or late afternoon: easier parking, softer light in the jameo, and cooler temps. Avoid midday if you can; the ascent feels longer under strong sun, and parking is toughest. The cable car lot closes at night, so don’t rely on it for after‑hours access.
