Demand drivers
Most guests drive up for a short stay rather than fly in for a week. That is why the weekend and holiday swing the Sheriff describes is so pronounced, and why minimum stays, holiday rules and gap nights need deliberate handling rather than a default setting.
Snow is the draw and the obstacle in the same weekend. County guidance calls a road passable under eight inches of snow and open to travel with a properly equipped vehicle carrying chains on all drive wheels; open means one plow pass and clear means two. Caltrans publishes current highway conditions. A guest who cannot picture the arrival does not book.
Lake Gregory is a County regional park in Crestline with 2.3 miles of trails, a summer swim beach and inflatable waterpark, year-round non-powered boating and fishing, and a dog park. Lake Arrowhead is private, and the Association says membership is required for boating access. One is a public booking story; the other is an address-by-address question.
Lake Arrowhead Village promotes regional activity including the tour boat, Heaps Peak Arboretum and SkyPark. Alongside it there is a quieter demand for a wooded cabin with nothing scheduled, which is often what a Twin Peaks or Blue Jay home is really selling.
The operating year
Planning context from County and destination sources. Not a demand forecast and not a monthly revenue allocation.
The guest: a snow weekend, often booked on short notice against a forecast.
The work: a named plow responsibility, chain and route guidance, freeze protection, a warm arrival and a lit path. County rules require parking areas to stay clear of obstructions including excessive snow, and a snow-removal contact posted inside the unit.
The guest: quieter shoulder stays and early Village days.
The work: the thaw review. Drainage, decks, roof debris, access surfaces, heating and moisture control, before the exterior photographs are used again.
The guest: families escaping the heat below, with Lake Gregory's beach season as the anchor and the lake open 10 a.m. to 5 p.m.
The work: outdoor space, shade, pet handling, and turnover capacity through the busiest stretch.
The guest: colour, quiet and cabin gatherings.
The work: the fire-aware reset. County standards require the exterior to be free of pine needle and leaf litter on the ground or roof, weeds over four inches, dead trees and shrubs and unstacked wood.
Booking-window questions
These are questions, not answers. The answers are property-specific and belong in the Owner Portal, not on a public page.
Stay mix
This is what the County regulates. A permit is required to advertise and rent a home for 30 consecutive calendar days or less in the unincorporated mountain and desert regions, the approved occupancy is a ceiling that advertisements may not exceed, and the County permit number has to appear in listings on hosting platforms. Nearly all weekend and holiday demand here sits in this bracket.
Longer stays fall outside the County's short-term rental definition, which changes the permit and tax picture rather than removing it. They also change what the home needs: connectivity, laundry, a workspace and a kitchen that can cook properly. Confirm the treatment for your own situation, and check the private documents, which often speak to minimum stays directly.

Keep researching
There are two, and they are shaped differently. Winter demand follows snow and arrives late against a changing forecast. Summer demand follows Lake Gregory's beach season and the drive up out of the heat. Both concentrate on weekends and holidays, which is consistent with the Sheriff's description of a resident population of nearly 36,000 swelling past 85,000 on weekends and holidays.
Because a regional figure would be wrong for most homes. Results depend on the address, the access, the permitted occupancy and your own dates. Property-specific numbers are handled in the Owner Portal.
Both, in the same weekend. It creates the reason to come and it creates the reason to cancel. County snow guidance separates a passable road from an open or clear one and says passable travel may need chains on all drive wheels, so a clear arrival plan is part of the product.
Lake Gregory is a San Bernardino County regional park, so its recreation can be described as public visitor information rather than a property right. Lake Arrowhead is private and the Association says membership is required for boating access, which is a separate, address-specific question.
