Monte Holiday Treehouses

Four ways to sleep among the treetops

Monte Holiday is a campsite in the Sierra Norte, in the municipality of Gargantilla del Lozoya, which as well as pitches and bungalows has wooden cabins raised on platforms beside the trees. They are 4 metres off the ground, and those built on the slope reach 7. From the terrace you see the upper Lozoya valley and the Sierra de Guadarrama.

They are not all the same, and it pays to choose carefully:

• Nest cabin without a toilet: 3 × 2 metres, a 110 cm mattress, light, a microwave and a heater. It is handed over without sheets or towels: bring a sleeping bag. It is for two.
• Family cabins with a toilet: 12 m², a 120 cm bed, bunks or trundle beds for the children, a microwave, a mini fridge and a heat pump. The toilet has a basin and WC, but no shower.
• Large cabin with shower: 18 m² and a 12 m² terrace, a 135 cm bed and three 80 cm beds. It is the only raised one that admits a dog.
• Panoramic cabin: full bathroom and air conditioning, for two adults and two children.

The maximum rate published for 2026 runs from €72 a night in the nest cabin to €296 in the large one with shower and in the panoramic. The actual price depends on the date, and the minimum number of nights changes with the calendar.

What the night up there is like

In winter the sierra freezes, and the difference between cabins is noticeable. Those with a toilet or bathroom have a heat pump; the nest cabin has only an electric heater, so bring a winter sleeping bag. If your cabin has no shower, the shared shower and toilet block is nearby, with hot water and heating 24 hours a day. At night, going down the steps to the bathroom is part of the plan.

With small children, the terraces have railings and the stairs have gates that close at the top and bottom; if your child is small and sleeps in a bunk, ask beforehand about the top bunk. The cabins are in a pedestrian area: you park in your space and walk the last stretch with your luggage.

Mobile coverage is weak and wifi only reaches reception and the restaurant properly. Do not expect to be able to work remotely.

What works in each season

The site is open all year, but the services are not. On weekdays in winter, the restaurant El Fogón de Guille and the children's entertainment close; they open Friday, Saturday and Sunday. The pool opens at weekends in June and every day during the school holidays. The farm, the rope course and the zip line are paid separately and booked on the website. Every morning you can order bread at reception.

Reception is open from 8:00 to 23:30, and at that time the car barrier closes (at midnight in the pool season). If you arrive later, the car stays outside and you walk in. The Alsa bus between Madrid and Rascafría stops at El Tomillar, about a 20-minute walk away.

By car, Rascafría is about 20 minutes away. From there you have the El Paular monastery and, going up to Cotos, the Laguna Grande de Peñalara.
