1-Introduction At the same time increasing the range of tourism options and more competitive in the tourism destinations, the idea used of brand destination to increase value is the many attention(Williams, Gil And Chara 2004; 149). To measure destination brand equity, attention to its constituent elements is necessary. So far, some of the ways to increase destination brand equity, such as creating a strong emotional attachment through destination loyalty and destination image is examined. But, the effect of enduring travel involvement, as the interest rate to  travel is a new ideas. Review of enduring travel involvement studies, has shown that it play a constructive role in developing destination brand equity(McIntyre, 1989; 596). Therefore, in this study, the rol of enduring travel involvement in the development of brand equity is examined. In this study, by reviewing relevant research literature, the travel enjoyment, the importance of travel and tourist self-expression as three constituent elements on enduring travel involvement is intended. Then, the impact of enduring travel involvement on the destination brand awareness, destination brand image, destination brand quality and  destination brand loyalty as factors influencing the development of destination brand equity,  is studied.  2- Theoretical bases 2-1- Enduring travel involvement: Enduring travel involvement is a person’s baseline involvement, which is the default state reflecting the amount of interest, arousal, or emotional attach- ment one has with travel. It occurs even when the action of travel is not operative or one is not planning a trip or visiting a destination. Such interest in travel may arise from an individual’s perception that travel meets important values and goals. Endur- ing travel involvement is the value that one prescribes to the pleasure of travel. 2-2- Travel enjoyment: This measure is conceptualized as the acknowledged significance of an activity (in this case an adventure tourism activity) and the pleasure derived from participation in that activity. This enjoyment dimension was created using items related to importance of participation and enjoyment (Beckman, 2013). 2-4- Travel Importance: The third dimension of enduring involvement. If the activity is important to the consumer, then the consumer will be more involved with the activity and it will place a greater meaning to that adventure consumer. According to Mittal (1989), importance is a primary factor for an enduring and lasting involvement (Beckman, 2013). 2-5- Destination brand awareness:  Destination brand awareness is consumer's ability to recognize or recall a brand specific destination that create destination image in the minds of potential tourists (Koneknik and Gartner, 2007). 2-6- Destination brand image: Destination brand image is defined by Woodward (2000) as, "Brand perceptions of the brand that reflected in the consumer's mind by brand associated markers (Imani khoshkhoo and Aubi Yazdi, 1389). 2-7- Destination brand loyalty: Destination brand loyalty is a situation that indicates how likely a customer is to bring another brand, especially when that brand is no change in price or other aspects of product creation is stopped (Iranzadeh et al, 1391). 2-8- Destination brand quality: Perceived quality of the brand, is the consumer's perception of the overall quality or superiority of a product or service than other products or services (Imani khoshkhoo and Aubi Yazdi, 1389). 3- Discussion In this paper, after examined conceptual model by using smart pls software, it became apparent conceptual model is a good fit. Then hypotheses were examined. Results indicate that all hypotheses were confirmed. The result of examined hypotheses study showed in down table.   result t-v The path coefficient hypotheses confirm 2/115 0/275 Travel enjoyment has a positive and direct impact on Enduring travel involvement. confirm 5/236 0/445 Travel Importance has a positive and direct impact on Enduring travel involvement. confirm 2/526 0/268 Self-Expression has a positive and direct impact on Enduring travel involvement. confirm 4/289 0/455 Enduring travel involvement has a positive and direct impact on destination brand awareness confirm 2/859 0/338 Enduring travel involvement has a positive and direct impact on destination brand Image. confirm 4/011 0/437 Enduring travel involvement has a positive and direct impact on destination brand quality. confirm 3/56 0/270 Destination brand awareness has a positive and direct impact on destination brand loyalty. confirm 2/723 0/330 Destination brand image has a positive and direct impact on destination brand loyalty. confirm 2/320 0/231 Destination brand quality has a positive and direct impact on destination brand loyalty. confirm 8/011 0/654 Destination brand loyalty has a positive and direct impact on destination brand equity.   4– Conclusion The target study is exploring the relationship between enduring travel involvement and destination brand equity. To check the hypotheses used of structural Equation modeling and smart pls softwar. A structural equation model showed the conceptual model is a good fit.  Also, it was found that all the hypotheses of the study were approved. Examined hypotheses study showed that Isfahan enduring travel involvement is clouding travel enjoyment, self-Expression and travel Importance as three factors affecting of it. This factors whit the path coefficients 0/275, 0/445 and 0/268 have a positive  and direct impact on Enduring travel involvement. The path coefficients showed that travel Importance is greatest impact on enduring travel involvement. Examined hypotheses study showed that enduring travel involvement as interest to tourist travel tourisn destination by influence on destination brand awareness (the path coefficients=0/455), destination brand Image (the path coefficients=0/338) and destination brand quality (the path coefficients=0/437) has a positive and direct impact on destination brand loyalty. Also result of study showed the destination brand loyalty (the path coefficients=0/654) has a positive and direct impact on destination brand equity. Than we can say that tourists whit greatly interest to tourim destination (Isfahan city in this study), have most awareness and best image and of destination brand . Also tourists whit greatly interest to tourim destination have most loyalty to destination brand and of this way it increas the destination  brand equity. 5– Suggestions 1) create an enjoyable experience for tourists. 2) Increase importance of travel to destination for tourists. 3) reduce the risk of perceptual tourists and increase their self-expression. 5) improve the tourism destination promotions system. 6) Create flexible city tourist attractions.
